display, by the second electronic device, a fourth interface, when the second electronic device entering a screen-locked state, wherein the fourth interface is a screen-locked interface;
stop, by the first electronic device, display of the third interface;
display, by the first electronic device, a fifth interface after stopping display of the third interface;
send, by the first electronic device, data of the fifth interface to the second electronic device; and
display, by the second electronic device, a sixth interface, wherein the sixth interface and the fifth interface are the same.
2. The system of claim 1 , wherein the second electronic device is further configured to:
receive a screen locking instruction from the first electronic device; and
enter the screen-locked state based on the screen locking instruction.
3. The system of claim 2 , wherein the first electronic device is further configured to:
send a screen locking instruction to the second electronic device causing the second electronic device to enter the screen-locked state in response to the screen locking instruction.
4. The system of claim 2 , wherein the screen locking instruction includes screen-locked interface data, and wherein the screen-locked interface data is used to instruct the second electronic device to display the screen-locked interface corresponding to the screen-locked interface data.
5. The system of claim 1 , wherein the system is further configured to cause the second electronic device to enter the screen-locked state automatically without user operation on the second electronic device.
6. The system of claim 1 , wherein the system is further configured to:
display, by the first electronic device, a fifth interface after the first electronic device stops displaying the third interface;
send, by the first electronic device, data of the fifth interface to the second electronic device; and
display, by the second electronic device, a sixth interface, wherein the fifth interface and the sixth interface are the same.
7. The system of claim 6 , wherein the fifth interface is an interface of the first application.
8. The system of claim 1 , wherein the first interface is an interface of a first application, and wherein the third interface is an interface of a second application.
9. The system of claim 1 , wherein the third interface compromises at least one of: a notification message, a character, a picture, a video, or a program icon.
10. A method, comprising:
establishing, by a first electronic device, a coupling to a second electronic device for screen projection;
displaying, by the first electronic device, a first interface;
sending, by the first electronic device, data of the first interface to the second electronic device;
displaying, by the second electronic device, a second interface, wherein the second interface and the first interface are the same;
displaying, by the first electronic device, a third interface after stopping display of the first interface; and
displaying, by the second electronic device, a fourth interface, when the second electronic device enters a screen-locked state, wherein the fourth interface is a screen-locked interface.
11. The method of claim 10 , further comprising:
receiving, by the second electronic device, a screen locking instruction from the first electronic device; and
entering, by the second electronic device, the screen-locked state based on the screen locking instruction.
12. The method of claim 11 , further comprising:
sending a screen locking instruction to the second electronic device causing the second electronic device to enter the screen-locked state in response to the screen locking instruction.
13. The method of claim 11 , wherein the screen locking instruction includes screen-locked interface data, and wherein the screen-locked interface data is used to instruct the second electronic device to display the screen-locked interface corresponding to the screen-locked interface data.
14. The method of claim 10 , wherein the second electronic device enters the screen-locked state automatically without user operation on the second electronic device.
15. The method of claim 10 , wherein the method further comprises:
displaying, by the first electronic device, a fifth interface after the first electronic stops displaying the third interface;
sending, by the first electronic device, data of the fifth interface to the second electronic device; and
displaying, by the second electronic device, a sixth interface, wherein the fifth interface and the sixth interface are the same.
16. The method of claim 15 , wherein the first interface is an interface of a first application, and the third interface is an interface of a second application.
17. The method of claim 10 , wherein the fifth interface is an interface of the first application.
18. The method of claim 10 , wherein the third interface compromises at least one of; a notification message, a character, a picture, a video or a program icon.
19. A first electronic device, comprising:
a processor; and
a memory coupled to the processor and configured to store programming instructions that, when executed by the processor, cause the first electronic device to:
establish a coupling to a second electronic device;
display a first interface;
send data of the first interface to the second electronic device;
display a third interface after stopping display of the first interface; and
send a screen locking instruction to the second electronic device causing the second electronic device to enter a screen-locked state in response to the screen locking instruction.
20. The first electronic device of claim 19 , wherein the first electronic device is configured to:
display a fifth interface after the first electronic stops displaying the third interface; and
