Abstract

The invention discloses a picture loading method of an Android system, which is used for loading a picture in a three-level caching mode, and comprises the following steps of: S1, judging whether thepicture is cached or not, and if so, directly reading and loading the picture from a cache; s2, creating a thread pool; s3, storing the data to a memory and a local; s4, searching whether the currentpicture is cached or not in a memory, and directly loading and displaying the picture if the current picture is cached; if the current picture is not cached exists, executing the next step; s5, locally searching whether the current picture is cached or not, if so, storing the picture into a memory for caching, and loading and displaying the picture; if not, executing the next step; and S6, downloading the picture from the network, then storing the picture locally, storing the picture in a memory cache, and then loading and displaying the picture. Through a three-level caching mode, the pictureloading efficiency is improved, the server pressure is reduced, and the downloading flow is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a picture loading method of an Android system. Background technique [0002] In current mobile devices, such as smartphones based on the Android system, an APP has a very high usage rate for image loading. Sometimes dozens of images need to be loaded on a page, and the reuse rate for images is also very high. High, for example: user's avatar, product picture, etc. In a list page, the reuse rate of pictures is also very high. When we slide the screen, the number of pictures will continue to increase, and the pictures that are removed from the screen are usually processed. At this time, the garbage collector will also think that you no longer hold references to these pictures, and thus perform GC (garbage collection) operations on these pictures. If in order to make the program run quickly and load pictures on the interface quickly, we need to consider that after some pict...
