Reverting animation done with AnimatorSet

Question

I am creating an animation with AnimatorSet and when it ends I would like to leave the View where it was.

The code is something like this:

mLastAnimation = new AnimatorSet();
mLastAnimation.playTogether(
  ObjectAnimator.ofFloat(mImageView, "scaleX", 1.5f, 1f),
  ObjectAnimator.ofFloat(mImageView, "translationY", 40f, 0f));
mLastAnimation.setDuration(3000);
mLastAnimation.addListener(this);
mLastAnimation.start();

// The Activity implements the AnimatorListener interface
  @Override
  public void onAnimationEnd(Animator animator) {
    // Undo the animation changes to the view.
  }

EDIT:

I am using the new animation API so setFillAfter() will not work here.

Answer 1

If you are using nineoldandroids there is a function called reverse. You can set the duration to be 0 and call reverse to reverse the animation.

Answer 2

You have to set the properties of the View back to its original values.

For example if you translateY 40 pixels forward, you need to translateY 40 pixels backwards. This is because the actual properties of the View have changed during property animation, not just the way it is rendered.

Answer 3

While using ObjectAnimator you can simply set

android:repeatMode="reverse"

Answer 4

You can use this:

ObjectAnimator scaleX = ObjectAnimator.ofFloat(mImageView, "scaleX", 1.5f, 1f);
// here is the important part!
scaleX.setRepeatMode(ValueAnimator.REVERSE);
scaleX.setRepeatCount(1);
ObjectAnimator transl = ObjectAnimator.ofFloat(mImageView, "translationY", 40f, 0f));
// here is the important part!
transl.setRepeatMode(ValueAnimator.REVERSE);
transl.setRepeatCount(1);

mLastAnimation = new AnimatorSet();
mLastAnimation.playTogether(scaleX, transl);
// the rest is the same...
