Abstract:
1. A method for providing folder item information based on a touch operation, wherein the method comprises: determining first position coordinates of touch points on a display screen when an input event of touch zooming interaction occurs, and second position coordinates of the touch points on the display screen after the input event of touch zooming interaction occurs, wherein the input event of touch zooming interaction includes at least three touch points on the display screen; calculating, an area of a first polygon formed by the first position coordinates of the touch points, and an area of a second polygon formed by the second position coordinates of the touch points; calculating, a ratio of the area of the first polygon to the area of the second polygon, or a difference between the area of the first polygon and the area of the second polygon; determining, according to the ratio of the area of the first polygon to the area of the second polygon or the difference between the area of the first polygon and the area of the second polygon, a changed display status type of folder items in a window; acquiring corresponding data sources and layout definition files according to the changed display status type; and displaying the folder items according to acquired data sources and the layout definition files.
