android:GIF动画循环完成监听器 [英] android : GIF animation cycle complete Listener

问题描述

我有一张 GIF 图像，想在启动画面中加载.我遇到了几个像 android-gif-drawable 这样的库 和 Glide

I have one GIF image and want to load in Splash Screen. I came across few libraries like android-gif-drawable and Glide

有什么办法可以让我听完一个动画周期吗?我的意思是一旦动画周期完成(整个动画完成，不重复)我想要一个监听器，动画完成，并为我们提供一些回调.有点像:

Is there any way I can listen for one animation cycle complete ? I mean once animation cycle is complete(whole animation is completed, without repeating) I want a listener, that Animation is complete, and provides us with some callback. Somewhat like:

SomeLibrary.load("GIF")
.into(imageview)
.repeat(false)
.setOnAnimationCompleteListener(new OnAnimationCompleteListener(){
    public void onAnimationComplete(){
        // Animation is completed. Do whatever you want to do..
    }
});

我使用过这两个库，但正在寻找我上面提到的功能.

I have worked with both libraries But looking for a feature as I mentioned above.

推荐答案

对于 Glide V4，我发现这是最好的答案.https://github.com/bumptech/glide/pull/3438

For Glide V4 I've found this to be the best answer. https://github.com/bumptech/glide/pull/3438

Glide.with(this).asGif().load(/*your gif url*/).listener(new RequestListener<GifDrawable>() {
    @Override
    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<GifDrawable> target, boolean isFirstResource) {
        return false;
    }

    @Override
    public boolean onResourceReady(GifDrawable resource, Object model, Target<GifDrawable> target, DataSource dataSource, boolean isFirstResource) {
        resource.setLoopCount(1);
        resource.registerAnimationCallback(new Animatable2Compat.AnimationCallback() {
            @Override
            public void onAnimationEnd(Drawable drawable) {
                //do whatever after specified number of loops complete
            }
        });
        return false;
    }
}).into(imageView);
