Android Display Network GIF pictures

This feature is derived from the ability to add a display GIF to the app.

Android comes with controls that do not support GIF images, many of which support GIF images by extending imageview or view, but after android4.0, you need to turn off hardware acceleration for use and memory overflow issues.

Two open source packages were found on the Internet to display GIF images

Android-gif-drawable view controls that support GIF display

Project Address: https://github.com/koral--/android-gif-drawable

With JNI implementation, the compiler generates so library directly after the XML definition view, it is said that the performance is better, can also be better to avoid memory memory overflow problem.

To add an Android studio project using:

Build.gradle file dependencies Add content:

dependencies {

Compile ' pl.droidsonroids.gif:android-gif-drawable:1.1.+ '/* * Add GIF Control Library Reference */

}

Xutils

Project Address: Https://github.com/wyouflf/xUtils

Contains a lot of useful Android tools, the main use it to download files
