Android에서 AnimationDrawable로 끝나는 애니메이션을 반대로

Question

Android에서 AnimationDrawable을 반전하는 방법.

내 앱을 최적화하려면 애니메이션이 끝날 때 되돌리기를 원합니다. 나는 애니메이션이 5 개 새로운 이미지를로드하는 것이 아니라 방향을 변경하고자하지만 난 그렇게하는 방법을 발견하지

AnimationDrawable animation = new AnimationDrawable(); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball1), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball2), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball3), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball4), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball5), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball6), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball5), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball4), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball3), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball2), 100); 
    animation.addFrame(getResources().getDrawable(R.drawable.ball1), 100); 
    animation.setOneShot(false); 

    ImageView imageAnim = (ImageView) findViewById(R.id.image_view1); 
    imageAnim.setBackgroundDrawable(animation); 

    animation.start();

여기 내 코드입니다.

public class ReverseInterpolator implements Interpolator { 
    @Override 
    public float getInterpolation(float paramFloat) { 
    return Math.abs(paramFloat -1f); 
    } 
} 


animation.setInterpolator(new ReverseInterpolator());
