Problems solved by technology

[0005] Since image processing has the characteristics of large amount of data and a large amount of calculation, if it is processed directly under the main thread, it is easy to get stuck, especially on the Android platform, the access of SD card (SecureDigitalMemoryCard, secure digital card) is relatively slow. In the case of a large number of pictures, there may even be ANR (Application Not Responding, the application is not responding) phenomenon, so the smoothness of picture thumbnail display is relatively low

Abstract

The invention provides a picture thumbnail display method. The method comprises the following steps that a first thread starts a second thread and a third thread; a second thread terminal scans picture files to obtain a picture file list to be displayed, and transmits the picture file list to the first thread; the first thread requests to load a picture thumbnail from the third thread according to the picture file list to be displayed; the third thread acquires thumbnail data which correspond to each picture file to be displayed, and returns the thumbnail data to the first thread; the first thread displays a thumbnail which corresponds to the picture file to be displayed through a picture display control according to the thumbnail data. Through implementation of the picture thumbnail display method, asynchronous loading processing can be performed on picture thumbnails, the lagging phenomenon is avoided, and the display smoothness of the picture thumbnails can be enhanced. Moreover, the invention further provides a picture thumbnail display device.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for displaying picture thumbnails. Background technique [0002] In existing operating system platforms, especially mobile device operating system platforms, the system platform often needs to display picture thumbnails because users browse files or visit webpages. [0003] In the prior art, displaying picture thumbnails is often done by combining view display controls to complete the loading, decoding and displaying of picture thumbnails in the main thread. For example, in the Android (Android, a free and open source operating system based on Linux) platform, by combining the GridView (grid view) control or the ListView (list view) control, the thumbnails are loaded on the main thread, decode and display. [0004] The inventor found in the research that there are at least the following technical problems in the prior art: [0005] Since image processing ...
