In some embodiments, the Android system is divided into four layers, which are, from top to bottom, the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer. The application layer can consist of a series of application packages.

As shown in Figure 2, combined with the description of the embodiment of the present application, the application package may include application programs such as lock screen and settings, wherein the lock screen application may control the display size and position of the interface elements on the wallpaper on the interface of the electronic device Coordinates and display effects, etc.

The application framework layer provides an application programming interface (a application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include window managers, content providers, view systems, phone managers, resource managers, notification managers, and so on.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc. In this application, the window manager may participate in the process of displaying the interface elements of the lock screen wallpaper on the display screen.

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build lock screen apps. A display interface can consist of one or more views. For example, the display of wallpaper on the display interface, or the display interface including dynamic interface elements on the wallpaper, may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide communication functions of the electronic device 100 . For example, the management of call status (including connected, hung up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to inform the user that the download is complete, message reminders, etc. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, or a notification is made by sounding, vibrating, or flashing an indicator light.

Android runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: surface manager (surface manager), media library (media libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc. 2D graphics engine is a drawing engine for 2D drawing.

In this application, the surface manager, the three-dimensional graphics processing library, etc. may participate in the display process of the interface elements of the electronic device, and the specific display process will not be repeated here.

The kernel layer is the layer between hardware and software. The kernel layer includes at least display drivers, sensor drivers, etc.

For ease of understanding, the following embodiments of the present application take the electronic device with the structure shown in FIG. 1 and FIG. 2 as an example, and describe the method for displaying the lock screen wallpaper provided by the embodiment of the present application in detail in combination with the drawings and application scenarios.

In the state of turning on the screen, the user can slide the screen to switch the wallpaper image displayed on the screen, and the switching process of the wallpaper image can correspond to the display process of different interface elements. A possible display process of the interface element is to move in a preset direction. Specifically, taking the wallpaper picture of a player playing football as an example, the football in the wallpaper picture is used as a dynamic interface element, and the football moves in a preset direction when the user slides the screen.

FIG. 3 is a schematic flowchart of a method for displaying a lock screen wallpaper provided by an embodiment of the present application. As shown in Fig. 3, the method may include S310, S320, S330 and S340.

It can be understood that, although the various steps of the method are presented in a specific order in the embodiments of the present application, the order of the steps can be changed in different embodiments. Alternatively, in some embodiments, one or more steps shown sequentially in this specification may be performed concurrently. Alternatively, in some embodiments, only part of the steps in FIG. 3 may be performed, for example, only S310 may be performed, or only S320 and S330 may be performed.

S310. The cloud server periodically sends lock screen wallpaper information to the electronic device. Correspondingly, the electronic device periodically receives the lock screen wallpaper information.

As an example, the cloud server may be a cloud server providing a lock screen wallpaper service.

For example, the cloud server can update the lock screen wallpaper information to the electronic device every day or every week.

S320. The electronic device sends request information to the cloud server, where the request information is used to request lock screen wallpaper information. Correspondingly, the cloud server receives the request information of the lock screen wallpaper information.

For example, after receiving an instruction input by the user requesting to update the lock screen wallpaper information, the electronic device sends request information for the lock screen wallpaper information to the cloud server.

S330. The cloud server sends lock screen wallpaper information to the electronic device based on the request information of the electronic device. Correspondingly, the electronic device receives the lock screen wallpaper information.

The lock screen wallpaper information in this embodiment may include at least one of the first parameter, the second parameter and the third parameter.

Wherein, the first parameter may include data information of one or more lock screen wallpapers, and the lock screen wallpapers may also be called lock screen wallpapers. As an example, the lock screen wallpaper may contain landscape images, human figure images, and the like.

The second parameter may include data information of one or more image elements corresponding to each lock screen wallpaper in at least one lock screen wallpaper. As an example, an image element may include any one or more elements in an image. For example, image elements may include footballs, satellites, cars, people, and so on.

As an example, when the first parameter (that is, the aforementioned first information) indicates N lock screen wallpapers, among the N lock screen wallpapers, M lock screen wallpapers may have corresponding image elements, that is, the second parameter (that is, the aforementioned second information) may indicate that the N An image element corresponding to each of the M lock screen wallpapers among the lock screen wallpapers, wherein each lock screen wallpaper may correspond to one or more image elements, and M is a positive integer less than or equal to N.

In this embodiment, a lock screen wallpaper with corresponding image elements may be called a dynamic wallpaper, and a lock screen wallpaper without corresponding image elements may be called a static wallpaper. The image element corresponding to the lock screen wallpaper means that when the lock screen wallpaper is displayed on the electronic device, the image element is superimposed and displayed.

The third parameter (ie, the aforementioned third information) may include a trajectory parameter of the image element. For example, the third parameter may include one or more positions of the image element in the corresponding lock screen wallpaper, or one or more display angles of the image element when the image element is superimposed on the corresponding lock screen wallpaper.

Optionally, the third parameter may indicate the location of the image element through a ratio. For example, the third parameter may include the following information: (positions in the x-axis direction: 0.1, 0.3, 0.8, 1.0), (positions in the y-axis direction: 0.5, 0.55, 0.55, 0.5). Among them, the combination of the first value 0.1 in the x-axis direction and the first value 0.5 in the y-axis direction can indicate that the image element is located at the following position on the image: with the lower left corner of the image as the origin, 10% of the image in the x-axis direction One place, one-half place on the y-axis direction, other ratios and so on.

Among them, an example of the x-axis direction is to take the lower left corner of the mobile phone screen facing the user as the origin, and move to the right along the short screen; an example of the y-axis direction is the lower left corner of the mobile phone screen facing the user As the origin, along the upward direction of the long screen.

Optionally, the third parameter may indicate the rotation angle of the image element through an absolute angle, or may indicate the rotation angle of the image element through a ratio. For example, the third parameter may include the following information: (rotation angle in the Z-axis direction: 0, 108, 252, 360). As another example, the third parameter may include the following information: (rotation angle in the Z-axis direction: 0, 0.3, 0.7, 1.0), then 0.3 indicates that the rotation angle of the image element is three-tenths of 360 degrees, that is, 108 degrees, and others ratio and so on.

An example of the z-axis direction is a direction along the screen to the user with the lower left corner of the mobile phone screen facing the user as the origin.

S340. The electronic device displays a user interface based on the user instruction and the lock screen wallpaper information.

In this application, after the electronic device receives the lock screen wallpaper information, it can record the lock screen wallpaper information; and after receiving the user's operation instruction in the lock screen state, it can display the corresponding lock screen wallpaper information based on the user's operation instruction. user interface.

As an example, a user's sliding operation with a sliding range is detected, and the display parameters corresponding to the sliding range are generated according to the sliding operation and the aforementioned second and third parameters, and the display parameters are used to draw the lock displayed in the user interface. screen wallpaper.

Taking the electronic device as a mobile phone as an example, an implementation manner of displaying a user interface based on a user's operation instruction and lock screen wallpaper information is introduced below.

As shown in FIG. 4 , FIG. 4 is a schematic diagram of a graphical user interface (graphical user interface, GUI) provided by an embodiment of the present application when the mobile phone is in a locked screen state. As shown in (a) of FIG. 4 , the mobile phone is in the lock screen mode, and its user interface 401 may be a black screen interface.

When the mobile phone detects the unlocking instruction, the mobile phone responds to the unlocking instruction and draws the lock screen wallpaper based on the received lock screen wallpaper information. For example, when the user's finger touches the screen, that is, when the mobile phone detects that there is a trigger instruction on the screen, the mobile phone responds to the trigger instruction and draws the lock screen wallpaper based on the received lock screen wallpaper information.

In some possible implementation manners, in response to the unlocking instruction, the mobile phone may first determine whether the target lock screen wallpaper is a static wallpaper or a dynamic wallpaper based on the lock screen wallpaper information. If it is a static wallpaper, the static wallpaper can be drawn directly based on the first parameter in the lock screen wallpaper information; if it is a dynamic wallpaper, it can be drawn based on the first parameter, the second parameter and the third parameter in the lock screen wallpaper information dynamic wallpaper.

In this embodiment, the target lock screen wallpaper includes the lock screen wallpaper to be displayed currently. Optionally, the target lock screen wallpaper may also include one or more lock screen wallpapers before the lock screen wallpaper to be displayed, and/or, one or more lock screen wallpapers after the lock screen wallpaper to be displayed.

For example, the first parameter indicates N lock screen wallpapers. When the mobile phone detects that there is a trigger command on the screen, it can draw S target lock screen wallpapers. A positive integer less than or equal to N. As an example, S is equal to 3 or equal to 5.

For example, the lock screen wallpaper information contains the data information of 1 series 2 related lock screen wallpapers, and the first lock screen wallpaper among the 12 lock screen wallpapers will be displayed after the mobile phone is unlocked, then the mobile phone can draw the 12th, 1st and 12th lock screen wallpapers. 2 lock screen wallpapers.

When judging whether the target lock screen wallpaper is a static wallpaper or a dynamic wallpaper based on the lock screen wallpaper information, as an example, the mobile phone may determine whether the lock screen wallpaper information includes the second parameter and/or the third parameter to determine whether it is a static wallpaper or a dynamic wallpaper. If it contains the second parameter and/or the third parameter, it is a dynamic wallpaper; if neither the second parameter nor the third parameter is contained, it is a static wallpaper.

When determining whether the target lock screen wallpaper is a static wallpaper or a dynamic wallpaper based on the lock screen wallpaper information, as another example, the mobile phone determines whether the information in the second parameter and/or the third parameter in the lock screen wallpaper information is empty. If the information in the second parameter and/or the third parameter is not empty, it is a dynamic wallpaper; if the information in the second parameter and the third parameter are both empty, it is a static wallpaper.

If it is a static wallpaper, the static wallpaper is drawn according to the first parameter, and the drawn static wallpaper can be stored in the buffer memory of the mobile phone display.

If it is a dynamic wallpaper, as the first example, the static wallpaper can be drawn according to the first parameter, and the image element can be drawn according to the second parameter, and then the image element and the static wallpaper can be superimposed (or synthesized) to obtain a dynamic wallpaper, and the The drawn dynamic wallpaper is stored in the cache memory of the mobile phone display.

If it is a dynamic wallpaper, as the second example, draw a static wallpaper according to the first parameter, and then draw image elements on the basis of the static wallpaper based on the second parameter, so as to obtain a dynamic wallpaper, and store the dynamic wallpaper to the cache of the mobile phone display middle.

In this embodiment, the lock screen wallpaper is drawn in advance before the screen is turned on, which can avoid the problem of slow response speed of wallpaper drawing caused by the real-time computing resources of the mobile phone being occupied by other applications, improve the smoothness of lock screen wallpaper switching, and further improve user experience. use experience.

After drawing the lock screen wallpaper on the mobile phone, turn on the screen and display the lock screen wallpaper. A user interface of the lock screen wallpaper displayed on the mobile phone is shown in the display interface 402 in (b) of FIG. 4 .

At this time, the display interface of the mobile phone screen is switched from the interface 401 in (a) to the interface 402 in (b). As an example, the interface 402 includes an image element 41 and an image element 42. The image element 41 is an image element contained in a static wallpaper, and the image element 42 is an image element that can move as the user touches the position.

When the user's finger operates on the screen, that is, when the mobile phone detects that there is a moving trigger instruction on the screen, the image elements can be displayed in corresponding changes according to the user's operation. FIG. 5 is a schematic diagram of a graphical user interface (graphical user interface, GUI) in a lock screen wallpaper display process provided by an embodiment of the present application. One of the changing processes of image elements is as shown in Fig. 5 (a) where the display interface 501 is transformed into the display interface 502 in (b).

As an example, the mobile phone responds to the user's sliding range, and the display interface of the mobile phone screen is converted from the interface 501 in (a) in Figure 5 (which may correspond to the interface 401 in (a) in Figure 4 ) to the one in (b) An interface 502, wherein the interface 501 includes an image element 52, the interface 502 includes an image element 53, and the image element 53 is an image element obtained by moving and rotating the image element 52.

Optionally, when the user's finger leaves the screen of the mobile phone or slides in the opposite direction of the aforementioned sliding direction, the interface on the mobile phone can be restored from interface 502 to interface 501 .

When the mobile phone displays the interface shown in (b) in Figure 5, if the user's finger continues to slide to the right on the mobile phone screen, that is, if the mobile phone detects that there is a continuous movement trigger command on the screen, the mobile phone screen can be displayed as shown in Figure 5 (c) shows the interface 503 . The interface 503 includes an image element 54 , and the image element 54 is an image element obtained by moving and rotating the image element 53 .

When the mobile phone displays the interface shown in (c) in Figure 5, if the user's finger slides to the right again on the mobile phone screen, that is, if the mobile phone detects that there is a continuous movement trigger command on the screen, the mobile phone screen can be displayed as shown in Figure 5 Figure (d) shows interface 504 . The interface 504 includes an image element 55 , and the image element 55 is an image element obtained by moving and rotating the image element 54 .

In the following, the image element indicated by the second parameter in the lock screen wallpaper information is football, and the third parameter contains the following content as an example: (position in the x-axis direction: 0.1, 0.3, 0.8, 1.0), (position in the y-axis direction: 0.5 , 0.55, 0.55, 0.5), (rotation angle in the z-axis direction: 0, 0.3, 0.7, 1.0) as an example, introduce the mobile phone to redraw image elements based on the screen size and sliding parameters generated by user operations to display the position of the image elements The implementation of the moving live wallpaper.

In this example, based on the four positions configured in the lock screen wallpaper information and the four angles corresponding to these four positions, the mobile phone can evenly select four amplitude values within the maximum slidable range of the target. These four amplitude values One-to-one correspondence with these four positions and four angles.

For example, a sliding range of 0 corresponds to the first position and first angle, that is, the initial position and initial rotation angle of the image element when the user's finger does not slide; the sliding range of the user's finger is one-third of the maximum sliding range of the target , the image element corresponds to the second position and the second rotation angle; when the sliding range of the user's finger is two-thirds of the maximum sliding range of the target, the image element corresponds to the third position and the third rotation angle; the user's When the sliding range of the finger is the maximum sliding range of the target, the image element corresponds to the fourth position and the fourth rotation angle.

Wherein, the target maximum slidable range refers to the maximum slidable range that does not cause the phone screen to be unlocked and does not cause the lock screen wallpaper to be switched. For example, if the user's sliding range in the sliding direction exceeds half (or 0.5) of the screen size of the mobile phone in the sliding direction, the mobile phone lock screen wallpaper will switch to the next page, and the target maximum sliding service is Corresponds to half the screen size in the direction of the swipe.

For example, as shown in FIG. 5 , the mobile phone detects the touch of the user's finger and lights up the screen, as shown in figure (a), where the screen displays an interface 501 including image elements 52 . At this time, since the sliding range of the user's mobile phone is zero, the position of the image element 52 in the short screen direction (equivalent to the x-axis direction) is 0.1 of the screen width; the position in the long screen direction (equivalent to the y-axis direction) is It is 0.5 of the screen width; the rotation angle of the image element toward the user (equivalent to the rotation angle of the z-axis toward the user) is 0 degrees.

Swipe the user's finger from the left edge of the screen to the right as shown in Figure (b). As an example, when the sliding range is one-third of the target maximum sliding range (that is, half the width of the mobile phone), the mobile phone is based on the first The three parameters can determine the position of the image element as the second position, and the rotation angle as the second rotation angle.

That is to say, the position of the image element in the direction of the short screen of the mobile phone is 0.3 of the width of the mobile phone screen, the position of the image element in the direction of the long screen of the mobile phone is 0.55 of the length of the mobile phone screen, and the rotation angle is 360*0.3 degrees. The mobile phone can redraw the image element on the mobile phone screen based on the position and rotation angle. An example of the drawn image element is shown as the image element 53 in (b) of Figure 5. The image element 53 is equivalent to moving the image element 52 from the initial position to the second position, and moving the image element 52 towards the outside of the screen. The orientation is rotated 108 degrees.

The user continues to slide the finger to the right to the position shown in (c). As an example, when the sliding range is two-thirds of the target maximum sliding range (that is, one-half of the mobile phone width), the mobile phone can determine based on the third parameter The position of the image element is a third position, and the rotation angle is a third rotation angle.

That is to say, the position of the image element in the direction of the short screen of the mobile phone is 0.8 of the width of the mobile phone screen, the position of the image element in the direction of the long screen of the mobile phone is 0.55 of the length of the mobile phone screen, and the rotation angle is 360*0.7 degrees. The mobile phone can redraw the image element on the mobile phone screen based on the position and rotation angle. An example of the drawn image element is shown as the image element 54 in (c) of Figure 5. The image element 54 is equivalent to moving the image element 52 from the initial position to the third position, and moving the image element 52 towards the outside of the screen. The orientation is rotated by 252 degrees.

The user continues to slide the finger to the right to the position shown in (d). As an example, when the sliding range is the target maximum sliding range (that is, half the width of the mobile phone), the mobile phone can determine the position of the image element based on the third parameter as In the fourth position, the rotation angle is the fourth rotation angle.

That is to say, the position of the image element in the direction of the short screen of the mobile phone is the edge of the mobile phone screen, the position of the image element in the direction of the long screen of the mobile phone is 0.5 of the length of the mobile phone screen, and the rotation angle is 360 degrees. The mobile phone can redraw the image element on the mobile phone screen based on the position and rotation angle. An example of the drawn image element is shown as the image element 55 in (d) of Figure 5. The image element 55 is equivalent to moving the image element 52 from the initial position to the third position, and moving the image element 52 towards the outside of the screen. The orientation is rotated 360 degrees (or not).

The above-mentioned embodiment introduces real-time redrawing of the moved and rotated image elements based on the sliding range of the user's finger. It can be understood that this is only an example, and this embodiment of the present application does not limit the drawing timing of the moved and rotated image elements. For example, after the mobile phone receives the lock screen wallpaper information, or after the user enters an instruction to light up the screen, image elements with different positions and different rotation angles can be drawn in advance based on the second parameter and the third parameter, and then when the user slides When the amplitude reaches a specific ratio, the lock screen graphics are displayed directly based on the drawn image elements.

It can be understood that the mobile phone may also be configured with the following information: the rule that the moving trajectory of the image element between any two adjacent positions indicated by the third parameter should satisfy. For example, between any two adjacent positions indicated by the third parameter, the image element may move along a straight line, or may move along a Bezier curve. Wherein, if moving along the Bezier curve, the smoothness of the moving track of the image element can be improved, thereby improving the display effect.

The information configured in the mobile phone may be delivered by the cloud server, or may be pre-configured in the mobile phone.

In the case where the mobile phone is configured with the above moving rules, when the sliding range of the user's finger is between the aforementioned two adjacent sliding ranges with uniform values, the mobile phone evenly takes M sliding ranges between the two adjacent sliding ranges, And based on this rule, M positions corresponding to the M sliding ranges are added between the two positions corresponding to the two adjacent sliding ranges, and even the two rotation angles corresponding to the two adjacent sliding ranges can be Add M rotation angles corresponding to the M sliding ranges one-to-one, and M is a positive integer. In this way, when the sliding range of the user's finger is equal to any sliding range in the M sliding ranges, the mobile phone can also draw the image element corresponding to the arbitrary sliding range in a similar manner as described above, and display the corresponding user interface. The position of the image element is the position corresponding to the arbitrary sliding range, and the rotation angle of the image element corresponding to the arbitrary sliding range is the rotation angle corresponding to the arbitrary sliding range.

This method of adding image elements corresponding to positions and rotation angles for more sliding ranges can improve the display effect of image elements.

Taking the rule that the image element moves along the Bezier curve between any two adjacent positions indicated by the second parameter as an example, the mobile phone can add M positions, and use a Bezier curve to smooth the M positions, try to make the M positions and any two adjacent positions form a Bezier curve.

As an example, after the Bezier curve smoothing process is performed on the position of the image element following the variation of the sliding range of the user's finger, an example of the moving track of the image element is shown as a dotted line in FIG. 6 . It can be clearly seen from Fig. 6 that the moving trajectory is more realistic.

In this embodiment, it can be understood that adjusting the position of the image element and the rotation angle in the z-axis direction with the change of the sliding range of the user's finger is only one way of improving the lock screen wallpaper and user interactivity in this embodiment. For example, as long as the screen is locked, the display effect of one or more image elements in the user interface displayed on the screen can change with the change of the finger sliding range, which should fall within the scope of protection of this embodiment. For example, the mobile phone can adjust the size, transparency, color, rotation angle in other directions, and so on of image elements as the user's finger slides.

Taking the image element in FIG. 5 as an example, FIG. 7 shows an example diagram of adjusting the size of the image element, the rotation angle in other directions, and the transparency according to the change of the sliding range of the user's finger.

As an example, the dynamic image element football can change as shown in (a) in FIG. 7 , the size of the football image element changes from 1 to n, and n is less than 1. When the size of the football image element is 1, the size of the element may be the maximum size, and the size of the football image element decreases gradually during the display process. When the size of the football image element is n, the size of the element may be the minimum size and be the final displayed standard size. It should be understood that the final displayed standard size is the size of the element seen by the user before the interface map is switched or restored to the original state. For example, it may be the size of the image element 55 on the interface diagram as shown in (d) of FIG. 5 .

Or, as an example, the football image element can have a changing effect as shown in (b) of FIG. 7 , the size of the image element gradually changes from 1 to n, and n is greater than 1. When the size of the football image element is 1, the size of the element may be the minimum size, and the size of the football image element gradually increases during the display process. When the size of the football image element is n, the size of the element can be the maximum size, which is the final displayed standard size. It should be understood that the final displayed standard size is the size of the element seen by the user before the interface map is switched or restored to the original state, which is not limited in this embodiment of the present application.

Or, as an example, the soccer image element can change as shown in (c) in FIG. When the size of the football image element is 1, the size of the element can be a standard size. During the display process, the size of the football image element is gradually reduced to be smaller than the final displayed standard size, and then gradually increased until the element size is 1, which becomes the final standard size, which is not limited in this embodiment of the application.

Optionally, it corresponds to the changing state of the rotation angle of the soccer ball during the display process of the dynamic image elements 52 to 55 in (a) to (d) of FIG. 5 .

As an example, the football image element can have a change effect as shown in (d) of FIG. 7 , and the angle of the image element is gradually rotated from 0° to 360°. When the rotation angle of the football image element is 360°, the angle of the element may be a standard angle size, and during the display process, the rotation angle of the football image element gradually rotates to the final displayed standard angle size. It should be understood that the final displayed standard angle size is the element angle seen by the user before the interface map is switched or when the original state is restored. For example, it may be the angular size of the image element 55 on the interface diagram as shown in (d) of FIG. 5 .

It can be understood that the rotation angle of the dynamic image element is not limited to the two-dimensional graphics in this embodiment, and it is also applicable to the situation when the dynamic image element is a three-dimensional graphics, and details will not be repeated here.

Optionally, it corresponds to the changing state of the transparency of the soccer ball during the display process of the dynamic image elements 52 to 55 in (a) to (d) of FIG. 5 . As an example, the football image element can have a change effect as shown in (e) of FIG. 7 , the transparency of the football image element gradually changes from 1 to n, and n is less than 1. When the transparency changes to n, the element's transparency size can be a standard transparency size, and during the display process, the transparency size of the football image element gradually changes to the final displayed standard transparency size. It should be understood that the finally displayed transparency is the transparency of the element seen by the user before the interface map is switched or when the original state is restored.

Optionally, it corresponds to the changing state of the football position during the display process of the dynamic image elements 52 to 55 in (a) to (d) of FIG. 5 . As an example, in combination with the size change process from (a) to (c) in FIG. 7 , as the football image element is displayed to the final displayed standard size, the position gradually moves to the preset position. For example, the image element 52 on the interface diagram as shown in (a) in FIG. 5 may move to the position of the image element 55 on the interface diagram as shown in (d) along with the size change process.

As another example, in combination with the change process of the rotation angle in (d) of FIG. 7 , as the football image element is displayed to the final displayed standard angle, the position gradually moves to the preset position. For example, it may be that the image element 52 on the interface diagram shown in (a) of FIG. 5 moves to the position of the image element 55 on the interface diagram shown in (d) along with the change process of the rotation angle.

As yet another example, in combination with the transparency change process in (e) of FIG. 7 , as the football image element is displayed to the final displayed standard transparency, the position also gradually moves to a preset position. For example, the image element 52 on the interface diagram as shown in (a) in FIG. 5 may move to the position of the image element 55 on the interface diagram as shown in (d) along with the transparency change process.

Optionally, it corresponds to the changing state of the blurring degree of the soccer ball during the display process of the dynamic image elements 52 to 55 in (a) to (d) of FIG. 5 . During the display process of the football element, the blur degree of the element gradually increases until it is completely blurred, which is the final displayed blur degree of the image element. It should be understood that the blurring degree of image elements can be realized by blurring algorithms, such as Gaussian blurring algorithm, mean value blurring algorithm, etc. The application does not limit the type of blurring control algorithm. For dynamic image elements, the pixels occupied on the display interface are 100×100, and for different blurring degrees, some pixels can be extracted from the 100×100 pixels for blurring processing. As an example, when the blur degree is 1, 5000 pixels are extracted from 100×100 pixels for blur processing; when the shepherd degree is 0.5, 1000 pixels are extracted from 100×100 pixels for blur processing, and the blur degree is 0 100×100 pixels are normally displayed, which is not limited in this embodiment of the present application.

Optionally, the mobile phone may obtain the sliding speed of the user's finger before leaving the screen when sliding, and display the dynamic image elements according to different display processes according to the sliding speed of the finger, so as to present animation effects. It should be understood that the different display processes of the dynamic image elements here can refer to the relevant introduction in the aforementioned Figure 7, and the dynamic image elements can change according to their own size, rotation angle, transparency, position and blur degree, etc. display, or the dynamic image element prolongs or shortens the duration of its own display to the final form according to the speed before the finger leaves the screen, etc., which will not be repeated here.

As an example, when the user slides the finger before leaving the screen at a speed of 10 pixels per millisecond (pixel/millisecond, px/ms), the size of the dynamic image element itself changes, the rotation angle changes, the change of different transparency, different The change of position and the change of blur degree are completed within 100ms to present the final effect, and it is determined whether to switch the interface map or enter the desktop according to the ratio of the finger displacement distance in the screen sliding direction to the screen size in that direction. When the speed of the user's finger before leaving the screen is 50px/ms when the user slides, the change of the size of the dynamic image element itself, the change of the rotation angle, the change of different transparency, the change of different positions and the change of blur degree are completed within 50ms. Present the final effect, and determine whether to switch the interface map or enter the desktop according to the proportion of the finger's displacement distance in the screen sliding direction to the screen size in this direction, which is not limited in the embodiment of the present application.

The faster the user slides his finger on the display screen, the shorter the interval between dynamic image elements changes. In other words, the faster the user slides his finger, the shorter the overall time for the dynamic image element to move to the final position to form the final interface image to complete the animation.

As an example, when the horizontal angle between the sliding track of the user and the short side of the mobile phone is 40°, the changes in the size of the dynamic image element itself, the change of the rotation angle, the change of different transparency, the change of different positions and the degree of blur The changes are completed within 100ms, and the final effect is presented. According to the ratio of the finger displacement distance in the screen sliding direction to the screen size in this direction, it is determined whether to switch the interface map or enter the desktop. When the horizontal angle between the sliding track of the user and the short side of the mobile phone is 30°, changes in the size, rotation angle, transparency, position, and blur degree of dynamic image elements are Complete within 50ms, present the final effect, and determine whether to switch the interface map or enter the desktop according to the proportion of the finger's displacement distance in the screen sliding direction to the screen size in this direction, which is not limited in this embodiment of the application.

As an example, as shown in Figure 8, when the user's finger continues to slide from the middle position of the screen in Figure (a) to the right as shown in Figure (b), that is, when the mobile phone detects that the trigger instruction on the screen exceeds the preset threshold, The display interface of the mobile phone screen is switched from the interface diagram 801 in (a) to the interface diagram 802 in (b). Wherein, the preset threshold value of the trigger command may be that the mobile phone detects that the displacement distance of the user's sliding accounted for half of the screen size parameter in the sliding direction; for example, when the short side size parameter of the mobile phone screen is ten centimeters, the user's finger When the displacement distance of sliding parallel to the short side of the screen exceeds five centimeters, the mobile phone detects the trigger command and performs the operation of switching the lock screen wallpaper.

Wherein, the static image element 81 and the dynamic image element 82 in the interface diagram 801 are covered or replaced by the image element 83, thereby generating the lock screen wallpaper shown in the interface diagram 802 in (b).

Optionally, the image element 83 may have been drawn and stored in the cache of the display, or when the mobile phone detects that there is a trigger instruction for switching the lock screen wallpaper on the screen, the image element 83 is drawn in real time to finally generate an interface The lock screen wallpaper shown in 802 is not limited here.

Optionally, the image element 83 in the interface diagram 802 can be a static element or a dynamic element; when the image element 83 is a dynamic element, when the mobile phone detects that there is a trigger instruction of the aforementioned image element on the screen, according to the dynamic rule Corresponding drawing is performed on the image element 83 to realize the dynamic display of the lock screen wallpaper.

It can be understood that the sliding to the right shown in the embodiment of the present application is only an example, and the present application does not limit the specific sliding direction or displacement distance.

As another example, when the mobile phone is in the unlocked state, when the user's finger continues to slide to the right on the screen beyond the preset ratio, that is, when the mobile phone detects that there is a trigger instruction for switching the lock screen wallpaper on the screen, the mobile phone screen displays an interface You can switch to the phone desktop.

Figure 9 is a schematic diagram of a graphical user interface (graphical user interface, GUI) in the display process of interface elements provided by the embodiment of the present application. In the interface 901 including the static interface element 91 and the dynamic interface element 92, when the user continues to slide the finger to the right for more than the preset range or time, that is, when the mobile phone detects that there is a lock screen wallpaper switching trigger command on the screen, the mobile phone screen switches to (b) The desktop shown in the interface 902 in the figure.

Optionally, the desktop of the aforementioned mobile phone in this application may be the main interface containing application icons, or it may be the interface operated by the user when the screen was turned on last time, for example, the user was using a video application when the screen was turned on last time, the interface diagram Staying on the interface of the video application, when the phone is in the unlocked state, when the user's finger continues to slide to the right on the screen beyond the preset ratio, that is, when the phone detects that there is a trigger instruction for switching the lock screen wallpaper on the screen, the phone screen The display interface can be switched to the interface of the aforementioned video application program. At this time, the interface diagram can include the background, icons, controls, menus, and playing videos of the video application, which are not limited in this embodiment of the present application.
