Problems solved by technology

[0004] A maximum of 9 small application icons can be displayed in the folder icon at a time, but the size of the folder icon is the same as that of the normal application icon, which leads to the fact that within the range of the size of the folder icon, the size of each application contained in the folder Small icons will look small, and users will not be able to clearly identify them, so this is not a good way to present content

Embodiment Construction

[0019] In the first step, draw the logic based on the existing folder icon ( figure 1 ), get the icons of all applications in the folder (more than 9, only select the first 9), perform certain scaling and arrangement, and then draw in the folder icon, the display effect is the existing "Nine Palaces" style;

[0020] The second step, on this basis, set the timer function. Use the timer interface provided by Android to implement the timer function, which is used to add 1 to the loop variable regularly (for example, every 1 second or every 2 seconds). Since the onAttachedToWindow() function is a symbolic function for the completion of view loading, it is used as an opportunity to start the timer, and the onDetachedFrowWindow() function is a symbolic function for the completion of view removal, so it is used as an opportunity to close the timer;

[0021] The third step is to select the icon of the i-th sub-application in the folder (1=< i <=n, n is the number of sub-applications ...

Abstract

The invention belongs to the technical field of application software and specifically relates to an Android-based method for file icon display. The method provided by the invention comprises two aspects that existing file icon drawing logics is changed; and a set of independent timed drawing functions is introduced. According to the invention, based on an existing "Sudoku" presentation mode, a large application icon is drawn additionally on the upper layer of a file icon, wherein the icon is one of the application icons contained in a file; icons of all the applications contained in the file are amplified and displayed cyclically; and all the applications in the file can be shown to a user clearly and visually. In this way, the problem in existing schemes that icons in files cannot be seen clearly can be avoided. According to the invention, timed switching of the application icons in the file can be achieved, wherein timed switching and amplified display are conducted according to an arrangement sequence of sub-applications.

Description

technical field [0001] The invention belongs to the technical field of application software, and in particular relates to a folder icon display method. Background technique [0002] Android is currently one of the most popular operating systems for mobile terminals, and various applications (Apps) installed by users are displayed on the system desktop. As we all know, as the number of installed applications increases, it will be inconvenient to search for an application page by page. Therefore, the Android system organizes the display of application icons to a certain extent, that is, the folder function: for example, a user can put multiple applications that he thinks has a certain relationship in the same folder, and then the user searches for a specific file folder, you can quickly locate an application you want to use, which facilitates the user's daily operations. [0003] Currently, the content presentation mode of the desktop folder of the Android system is: at most...
