An electronic device includes a display screen and at least one button. The display screen is a foldable screen. In a process in which a user uses the electronic device, a function that needs to be responded to by a button on the electronic device may be adaptively adjusted based on a physical form of the foldable screen of the electronic device, so that a button function that conforms to a using habit of the user can still be provided when the foldable screen of the electronic device is in a different physical form.
