Abstract: The second electronic device displays a first window and a second window. The first window includes first content projected by the first electronic device onto the second electronic device. The second window includes second content. The second electronic device sends received information about a first operation and the second content to the first electronic device, where the first operation is used to drag the second content from the second window to the first window. In response to the received information about the first operation and the second content, the first electronic device sends projection data including the first content and the second content to the second electronic device. In response to the received projection data, the second electronic device updates content in the first window to the first content and the second content.

Abstract: An object drag method includes a first terminal that displays an object on a display of the first terminal. The first terminal receives a drag operation from a user. The drag operation initiates a drag for the object. The first terminal displays, on the display of the first terminal in response to the drag operation, an animation in which the object moves with the drag operation. The first terminal sends drag data to a second terminal after determining that a drag intent of the user is a cross-device drag. The drag data enables the second terminal to display the object on a display of the second terminal.

Abstract: A first terminal displays a projection interface on a display of the first terminal, where content of the projection interface is a mirror of content of a first interface displayed on a display of a second terminal. The first terminal receives a first operation input, using an input device of the first terminal, to move a first cursor on the display of the first terminal. When the first cursor moves to the content of the projection interface, a cursor style of the first cursor is changed, or a display manner of the content is changed.
