1. A screen projection method, comprising:
displaying, by an electronic device, M application interfaces on a display of the electronic device, wherein M is an integer greater than 1;
receiving a first selection operation, and determining N application interfaces based on the first selection operation, wherein the first selection operation is performed on the electronic device to determine the N application interfaces selected from the M application interfaces, and N is a positive integer less than or equal to M; and
sending first data to an external display device in response to the first selection operation, wherein the first data is used by the external display device to display the N application interfaces, and wherein the first data comprises respective image data streams of the N application interfaces, and is used by the external display device to display the N application interfaces in N display windows in a one-to-one correspondence; and before the sending, by the electronic device, of the first data to the external display device, the method further comprises:
obtaining, by the electronic device, the respective image data streams of the N application interfaces.
