Electronic device, method for viewing desktop thereof, and computer-readable medium

Abstract

An electronic device, a method for viewing a desktop thereof, and a computer-readable medium are provided. One of n continuous areas of the desktop and a navigation bar are displayed in a touch screen of the electronic device. The navigation bar includes an indicator and n indexes, wherein the n indexes are respectively corresponding to the n areas, and the indicator points to the index corresponding to the area currently displayed in the touch screen. When a sliding operation applied to the indicator is detected on the navigation bar, the desktop and the indicator are moved according to the sliding operation. When the sliding operation terminates, an index closest to the indicator is selected from the n indexes as a target index. Finally, the indicator is controlled to point to the target index, and a target area corresponding to the target index is displayed in the touch screen.
