如何使用android fresco从动画webp中获取所有位图？

implementation 'com.facebook.fresco:fresco:2.5.0'

<com.facebook.drawee.view.SimpleDraweeView
    android:id="@+id/image_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

SimpleDraweeView imageView = findViewById(R.id.image_view);
Uri uri = Uri.parse("http://example.com/animation.webp");

ImageRequest request = ImageRequestBuilder.newBuilderWithSource(uri)
    .setAutoPlayAnimations(true) // 允许动画播放
    .build();

DraweeController controller = Fresco.newDraweeControllerBuilder()
    .setImageRequest(request)
    .setOldController(imageView.getController())
    .build();
imageView.setController(controller);
