Example 1
Fig. 1 shows a block diagram of a window cross-screen device based on an android system in an embodiment of the invention.
Referring to fig. 1, the present embodiment provides a window cross-screen device based on an android system, which is used for implementing a cross-screen operation in a vehicle-mounted entertainment system, where window cross-screen refers to moving an application program of one display screen 110 of the vehicle-mounted entertainment system onto a display window of another display screen 110 by dragging the display window of the display screen 110. The window cross-screen device is based on an installation system and specifically comprises at least two display screens 110, and in view of the fact that more display screens 110 are available in the current vehicle-mounted entertainment system, the window cross-screen device in the embodiment can move and display application programs on different target display screens from the interfaces of the current display screens 110, so that the display screens 110 in the embodiment are not limited to two, the number of the display screens 110 can be adjusted according to automobile requirements, and the application programs can be defined to be moved to the corresponding target display screens in a matching relation mode.
In a specific arrangement, the display screen 110 in this embodiment includes a processor 120 and a cross-screen control 130, where the processor 120 is configured to complete data processing during a cross-screen period of the window cross-screen device, and receive an input instruction of a user, for example, drag an application program on a current display screen by a touch manner, and after receiving the touch information, the processor 120 determines whether a cross-screen condition is met, so as to control the cross-screen control 130 to perform a corresponding operation.
The cross-screen control 130 includes at least an encapsulation module 131, a drag detection module 132, a target selection module 133, and a drag control module 134. In terms of functions, the packaging module 131 is mainly used for packaging the interface layout of the application program on the display screen 110, in the packaging process, the application program in the display screen 110 only needs to use the packaging module 131 in the cross-screen control 130 to perform interface layout, after packaging is completed, all operations are packaged by the subsequent cross-screen control 130, other requirements on the interface of the application program are avoided, and the application program can be normally used as a common packaging layout control and does not need to perform operations in other aspects.
The drag detection module 132 is mainly configured to identify external drag input, determine whether to make the packaged application enter a state capable of dragging across screens according to the drag input, for example, the processor 120 identifies the drag input through the drag detection module 132, and if the drag input operation determines that the drag input operation meets the condition of across screens, then enter a subsequent operation across screens. In particular, the drag detection module 132 determines whether the drag state is currently required to be entered, and the drag state is realized as "long-press" by default, and of course, the determination condition may be adjusted accordingly according to the user setting, for example, a specific gesture is defined, and gesture determination is performed by the gesture detection monitor, so as to realize other gesture state detection, such as double-click, sliding, and the like. When the cross-screen control 130 is set in an initial state or a default state, the application program is not draggable, and the user must enter a draggable state to move the sub-interface along with the dragging action of the user.
During the cross-screen operation, the processor 120 primarily utilizes the target selection module 133 to associate the target display screen with the current display screen and determine the drag direction. For example, if there are four display screens 110, the positions of the target display screens are defined in the up, down, left and right directions, the target screen is determined according to the dragging direction of the user, and the cross-screen operation of the application program interface is performed on the target screen. Since the screen installation positions will be different in different projects, the embodiment is not limited to specific settings, and can define the target display screens respectively represented by the top, bottom, left and right of the current screen and the information of the display screen 110 according to the requirements, so as to determine the target screen with the dragging direction and the moving direction and the position of the application program interface in the process of performing the cross-screen operation.
During the screen crossing period, the processor 120 controls the screen crossing action through the drag control module 134, specifically, after determining that the target display screen is good, the drag control module 134 determines, according to the drag information of the user, the interface drawing, the moving animation and the screen crossing state callback of the screen during the screen crossing. Specifically, during the screen crossing period, the normal interface drawing flow is adopted for drawing on the original screen, the screen capturing of the hidden part on the current display screen is obtained by drawing on the target screen through the dragging control module 134, a display window is created after the feedback information of the target screen is obtained, and then the screen capturing content is displayed on the target screen.
Preferably, the cross-screen control 130 further includes a screenshot control module, where the generation of the screenshot content can be obtained by the screenshot control module, and when the user starts dragging, the screenshot control module updates the position of the application program interface according to the position of the finger of the user, and when the interface has exceeded the current display screen, the exceeding part needs to be displayed on the target screen. For example, if the user drags to the right, the exceeding part is displayed on the corresponding target screen on the right side, and the exceeding part on the right side is intercepted by the screenshot control module and then displayed on the target screen.
To ensure that the target screen display and the display effect of the original screen appear as a seamless whole, the display position of the updated screen capture window on the target screen needs to be calculated according to the x, y coordinates of the encapsulation module 131 on the source screen. For this purpose, the cross-screen control 130 preferably further includes a coordinate conversion module for monitoring a touch position change of the current user, converting the current touch coordinate into an offset to the start touch position, and outputting the offset to the encapsulation module 131 and the drag control module 134.
In this embodiment, in a complete cross-screen operation process, after the window cross-screen device encapsulates the application program on the current display screen through the cross-screen control 130, the processor 120 displays the application program on the current display screen on the target display screen in a cross-screen manner according to the drag input of the user in the cross-screen direction of the target display screen.
The method has the advantages that the application programs in the vehicle-mounted display screen based on the android system are subjected to interface encapsulation through the original cross-screen control 130, and the cross-screen sliding of the vehicle-mounted entertainment system with a plurality of physical/virtual screens can be realized through the cross-screen control 130, so that the function of dragging one interface from one screen to another screen on the android system is realized, the requirements of UI cross-screen sliding and display are met, and the problem that the current vehicle-mounted display screen based on the android system cannot be subjected to cross-screen display is solved.
Preferably, the object selection module 133 is capable of associating a current display screen with a plurality of object display screens and implementing cross-screen display of different object display screens through different dragging directions. The drag directions include one or more of up, down, left, and right directions of the current display screen.

202. And acquiring and monitoring the triggering condition of the interface cross-screen dragging input of the application program.
In the use process of the display screen, the processor acquires the input of a user, wherein the input comprises but is not limited to touch input, voice input and action gesture input, the cross-screen control identifies whether the input confirms the dragging cross-screen action, in the identification, the cross-screen operation is in a settable state, if the current cross-screen operation is in a closed state, the identification action is not performed, if the cross-screen operation is in an open state, the input is judged, and whether the user performs the dragging cross-screen action is confirmed.
203. And after triggering the cross-screen dragging condition, determining a target display screen according to the dragging direction.
After confirming the initiation of the cross-screen action, the processor confirms a target display screen with the input information, wherein the target display screen is the equipment to be displayed after the application program crosses the screen. In this embodiment, the determination is determined according to a dragging direction of the user to the application program, for example, if the user drags the sub-interface from left to right to move and submerge in the edge of the current display screen, and in definition, the action corresponds to the direction as the display screen of the first target, then in the process of the cross-screen operation, the application program interface of the current display screen is moved to the display screen of the first target.
204. During the screen crossing period, a screenshot exceeding the current display screen interface is created through the dragging control module and displayed on the target screen, and after the dragging is completed, data callback is carried out, and the interface of the application program is redrawn on the target screen.

Referring to fig. 5, in this embodiment, the step of creating, by the drag control module, a screenshot exceeding the current display screen interface to be displayed on the target screen includes:
401. and acquiring information of the target screen, and drawing a screenshot of a display picture exceeding the current display screen interface in the dragging process in real time through a dragging control module.
402. The screenshot is displayed on the target screen.
Preferably, the screenshot action principle is that a bitmap is created, then the screenshot content of the sub-interface is filled in the bitmap object to return, and then the bitmap object is copied into the target display screen.
Preferably, the cross-screen dragging comprises two screen display modes of manual dragging and automatic moving, wherein the manual dragging is used for adjusting the movement of a screen of an application program interface between a current display screen and a target display screen in real time according to user dragging input; the automatic moving display mode switches the action of the picture of the application program interface between the current display screen and the target display screen through moving the animation. The manual dragging judges the position deviation delta x1 between the current position and the position of the user when the touch starts by monitoring the touch position information of the user on the display screen, and then invokes a program and sets the offset on the interface to realize the effect that the application program moves along with the movement of the finger touch position. In the automatic screen-crossing process, if the user does not drag slowly but moves the application from the original screen to the target screen quickly, a screen-crossing animation needs to be automatically played, and an animation display function needs to be adopted to realize animation display of the interface of the target and the original two display screens.
Referring to fig. 6, redrawing an interface forming the application on a target screen includes:
501. when the application program is completely invisible on the current display screen, ending the cross-screen operation;
502. sending a program callback to the application program, and hiding an application program picture of the current display screen;
503. drawing a new application program interface on the target display screen, hiding the screenshot on the target display screen and displaying the new application program interface.
When the user continues dragging, the application program interface is completely invisible on the source display screen, the cross-screen operation is finished, and the screenshot of the window on the target screen is completely displayed on the target screen at the moment, and the cross-screen operation is finished. At this time, the processor informs the application program of the state of the end of the cross-screen through the callback function, and after receiving the callback of the end of the cross-screen, the processor can perform corresponding processing.
