Abstract

A screen mirroring display method implemented by a first electronic device, where the method includes displaying a first display interface, receiving a screen mirroring instruction for projecting the first display interface onto a second electronic device, determining a first target control in the first display interface in response to the screen mirroring instruction, and sending a first message to the second electronic device, where the first message includes a drawing instruction of the first target control to prompt the second electronic device to draw a first screen mirroring interface according to the drawing instruction, where the first screen mirroring interface includes the first target control.

First claim

What is claimed is:

1. A method implemented by a first electronic device, wherein the method comprises:
displaying a first display interface;
receiving, from a user, a screen mirroring instruction for projecting the first display interface onto a second electronic device;
obtaining based on a type of the second electronic device, a configuration file corresponding to the first display interface,
determining, in response to the screen mirroring instruction and based on the configuration file, a first target control in the first display interface; and
sending a first message to the second electronic device,
wherein the first message comprises a first drawing instruction of the first target control to prompt the second electronic device to draw a first screen mirroring interface according to the first drawing instruction, and
wherein the first screen mirroring interface comprises the first target control.

2. The method of claim 1 , wherein the configuration file records the first target control on which screen mirroring needs to be performed in the first display interface.

3. The method of claim 2 , wherein the configuration file records an identifier or a display location of the first target control, and wherein the method further comprises determining, the first target control based on the identifier or the display location.

4. The method of claim 1 , wherein after determining the first target control, the method further comprises:
obtaining first view information for drawing the first display interface, wherein the first view information comprises a first layer order of first target controls in the first display interface; and
determining second view information based on the first view information, wherein the second view information comprises a second layer order of second target controls in the first screen mirroring interface, and wherein the first message further comprises the second view information, to prompt the second electronic device to draw the first screen mirroring interface based on the second view information and the first drawing instruction.

5. The method of claim 4 , further comprising splitting and recombining the first target controls in the first view information to obtain the second view information, wherein the first layer order and the second layer order are the same.

6. The method of claim 4 , wherein the configuration file further records display locations of the second target controls, and wherein the method further comprises:
splitting the first target controls from the first view information; and
recombining the first target controls based on the display locations to obtain the second view information.

7. The method of claim 1 , wherein the first message further comprises a drawing resource of the first target control, and wherein the drawing resource configured for drawing a user interface of the first target control when executing the first drawing instruction.

8. The method of claim 1 , wherein after displaying the first display interface, the method further comprises:
receiving, from the user, a second screen mirroring instruction for projecting the first display interface onto a third electronic device;
determining, in response to the second screen mirroring instruction, a second target control in the first display interface; and
sending a second message to the third electronic device, wherein the second message comprises a second drawing instruction of the second target control; or
sending the first message to the third electronic device, wherein the first message further comprises the second drawing instruction.

9. An electronic device, comprising:
a touchscreen;
a processor coupled to the touchscreen;
a memory coupled to the touchscreen and the processor and configured to store instructions, wherein when executed by the processor the instructions cause the electronic device to:
display a first display interface;
receive, from a user, a screen mirroring instruction for projecting the first display interface onto a second electronic device;
obtain, based on a type of the second electronic device, a configuration file corresponding to the first display interface;
determine, in response to the screen mirroring instruction and based on the configuration file, a first target control in the first display interface; and
send a first message to the second electronic device,
wherein the first message comprises a drawing instruction of the first target control to prompt the second electronic device to draw a first screen mirroring interface according to the drawing instruction, and
wherein the first screen mirroring interface comprises the first target control.

10. The electronic device of claim 9 , wherein the configuration file records the first target control on which screen mirroring needs to be performed in the first display interface.

11. The electronic device of claim 10 , wherein the configuration file records an identifier or a display location of the first target control, and wherein when executed by the processor, the instructions further cause the electronic device to determine the first target control based on the identifier or the display location.

12. The electronic device of claim 9 , wherein when executed by the processor, the instructions further cause the electronic device to:
obtain first view information for drawing the first display interface, wherein the first view information comprises a first layer order of first target controls in the first display interface; and
determine a second view information based on the first view information, wherein the second view information comprises a second layer order of second target controls in the first screen mirroring interface, and wherein the first message further comprises the second view information to prompt the second electronic device to draw the first screen mirroring interface based on the second view information and the drawing instruction.

13. The electronic device according to claim 12 , wherein when executed by the processor, the instructions further cause the electronic device to split and recombine the first target controls in the first view information to obtain the second view information, wherein the first layer order and the second layer order are the same.

14. The electronic device of claim 12 , wherein the configuration file further records display locations of the second target controls in the first screen mirroring interface, and wherein when executed by the processor, the instructions further cause the electronic device to:
split the first target controls from the first view information; and
recombine the first target controls based on the display locations to obtain the second view information.

15. The electronic device of claim 9 , wherein the first message further comprises a drawing resource of the first target control, and wherein the drawing resource is used by the second electronic device to draw a user interface of the first target control when the second electronic device executes the drawing instruction.

16. The electronic device according to claim 9 , wherein when executed by the processor, the instructions further cause the electronic device to:
receive, from the user, a second screen mirroring instruction for projecting the first display interface onto a third electronic device;
determine in response to the second screen mirroring instruction a second target control in the first display interface; and
send a second message to the third electronic device, wherein the second message comprises a second drawing instruction of the second
