More powerful and excellent open source framework: Android image loading and caching: Android Glide usage

Using Android Glide, you need to first download the Android Glide Library, Android Glide on GitHub on the project homepage:

Https://github.com/bumptech/glide.

The actual project use only needs to go to Glide's releases page to download the jar package and import it into the local libs to use directly. Glide's releases page address: https://github.com/bumptech/glide/releases, find the latest JAR package on this page, download it and put it in the Libs of your project, such as Glide Jar Package for 3.6.0 library: Https://github.com/bumptech/glide/releases/download/v3.6.0/glide-3.6.0.jar

The next step is to use it in your own project, and now give a concrete example of how to use it (load the image over the network and show it in ImageView):

Copy the downloaded jar file here:
