Display GIF animation (Frame Animation playback)

It is not convenient to display GIF images on Android. Although some controls can be implemented, the effect is not very good. It is safe to use frame animation for processing.
① Define animation-list in XML:
<? XML version = "1.0" encoding = "UTF-8"?>
<Animation-list xmlns: Android = "http://schemas.android.com/apk/res/android" Android: oneshot = "false">

<Item Android: drawable = "@ drawable/F_1" Android: Duration = "30"/>
<Item Android: drawable = "@ drawable/F_2" Android: Duration = "30"/>
<Item Android: drawable = "@ drawable/F_3" Android: Duration = "30"/>
<Item Android: drawable = "@ drawable/F_4" Android: Duration = "30"/>
</Animation-List>
② Define the imageview in the XML layout and specify its SRC or background attribute as "@ anim/loading"
③ In Java code:
Imageview = (imageview) findviewbyid (R. Id. Frame );
Animationdrawable drawable = (animationdrawable) imageview. getdrawable ();
// When using the background attribute
// Animationdrawable drawable = (animationdrawable) imageview. getbackground ();
Drawable. setoneshot (false); // Replay
④ Called in Java code:
Drawable. Start () or drawable. Stop () to play and stop an animation.
