Fresco: How to set loopcount for AnimatedImage after v1.4.0?

Ideally, your GIF would be properly formatted and have the loop count set to N.

Otherwise, you can create a modifying backend, something like this:

public class LoopCountModifyingBackend extends AnimationBackendDelegate {

  private int mLoopCount;

  public LoopCountModifyingBackend(
      @Nullable AnimationBackend animationBackend,
      int loopCount) {
    super(animationBackend);
    mLoopCount = loopCount;
  }

  @Override
  public int getLoopCount() {
    return mLoopCount;
  }
}

and then set it to your animated drawable:

final DraweeController controller = Fresco.newDraweeControllerBuilder()
    .setAutoPlayAnimations(true)
    .setUri(uri)
    .setControllerListener(new BaseControllerListener<ImageInfo>() {
      @Override
      public void onFinalImageSet(
          String id,
          @Nullable ImageInfo imageInfo,
          @Nullable Animatable animatable) {
        if (animatable instanceof AnimatedDrawable2) {
          AnimatedDrawable2 animatedDrawable = (AnimatedDrawable2) animatable;
          animatedDrawable.setAnimationBackend(new LoopCountModifyingBackend(animatedDrawable.getAnimationBackend(), 3));
        }
      }
    })
    .build();
simpleDraweeView.setController(controller);

You can also create a custom DrawableFactory that does this directly and then pass it when the image is rendered via PipelineDraweeController.

Thanks.

now for fresco 2.0.0+ ,how to do this?

works very well!
