A split-screen processing method comprising: displaying, by a terminal device, a first interface comprising a preset icon and a first application, wherein the preset icon is displayed above the first application in a floating manner; and displaying, by the terminal device, a first application list when detecting an input first user operation on the preset icon; dividing, by the terminal device, a screen of the terminal device into two or more subscreens when detecting an input second user operation on a second application in the first application list; and displaying, by the terminal device, the first application and the second application on a first subscreen and a second subscreen respectively, wherein the first subscreen and the second subscreen are comprised in the two or more subscreens; characterized in that when the input second user operation is an operation of touching and holding the second application in the first application list and sliding the second application to the left, the screen of the terminal is divided into a left subscreen and a right subscreen, the first subscreen being one subscreen among the left subscreen and the right subscreen and the second subscreen being the other subscreen among the left subscreen and the right subscreen, or when the input second user operation is an operation of touching and holding the second application in the first application list and sliding the second application upwards, the screen of the terminal is divided into an upper subscreen and a lower subscreen, the first subscreen being one subscreen among the upper subscreen and the lower subscreen and the second subscreen being the other subscreen among the upper subscreen and the lower subscreen. displaying, by a terminal device, a first interface comprising a preset icon and a first application, wherein the preset icon is displayed above the first application in a floating manner; and displaying, by the terminal device, a first application list when detecting an input first user operation on the preset icon; dividing, by the terminal device, a screen of the terminal device into two or more subscreens when detecting an input second user operation on a second application in the first application list; and displaying, by the terminal device, the first application and the second application on a first subscreen and a second subscreen respectively, wherein the first subscreen and the second subscreen are comprised in the two or more subscreens; characterized in that when the input second user operation is an operation of touching and holding the second application in the first application list and sliding the second application to the left, the screen of the terminal is divided into a left subscreen and a right subscreen, the first subscreen being one subscreen among the left subscreen and the right subscreen and the second subscreen being the other subscreen among the left subscreen and the right subscreen, or when the input second user operation is an operation of touching and holding the second application in the first application list and sliding the second application upwards, the screen of the terminal is divided into an upper subscreen and a lower subscreen, the first subscreen being one subscreen among the upper subscreen and the lower subscreen and the second subscreen being the other subscreen among the upper subscreen and the lower subscreen.
