animation - Is it possible to make the background of an android app into a animated background like a gif? -

-

i don't mean make gif background background moves. in advance. appreciated.

android not support gifs. workaround, android offers animation list/animationdrawable. need convert gif individual frames [.png files].

original gif image

this gif can broken down frames:

gif frames in gimp

save them frame01.png, frame02.png, , on, , create animation-list xml file, say, progress_animation.xml

<animation-list android:id="@+id/selected" android:oneshot="false"> <item android:drawable="@drawable/frame01" android:duration="50" /> <item android:drawable="@drawable/frame02" android:duration="50" /> <item android:drawable="@drawable/frame03" android:duration="50" /> .... <item android:drawable="@drawable/framen" android:duration="50" />

to begin animation, need cast image animationdrawable, , call start() on it

animationdrawable progressanimation = (animationdrawable) yourimageview.getbackground(); progressanimation.start();
  • other way:

android provides class android.graphics.movie. class capable of decoding , playing inputstreams. approach, ca create class gifmovieview , let inherit view:

public class gifmovieview extends view
