How to reset view to original state after using animators to animates its some properties?

I am using animators (ObjectAnimator) to animate few properties (scale, rotate) of a view.

Target view is animating properly when ObjectAnimators are set to it.

But there is an added requirement to get view to the original position (reset) after a while.

I tried to cancel() the animator but it only cancels the animation and doesn't reset the view.

Possible solution : creating another animator that does just opposite of the initial animator.

Is there any other way to reset it ?

Both ObjectAnimator.cancel() and ObjectAnimator.end() don't cancel the effects the animation had on the animated object, but rather just cancel its execution at the point in which the methods were called (see ValueAnimator's documentation for more details).

Now, I can think of three main ways to accomplish what you wanted:

  1. Put a listener on the ObjectAnimator, and when OnAnimationEnd/OnAnimationCancel is called, manully reset the properties of the view.
  2. If the properties of the view you want to reset are those given to it in the XML file, you can re-inflate it. For more details, check out this answer.
  3. Use the ObjectAnimator.reverse() method to reverse the execution of the animation, effectively reseting the properties of the view. Preferably, you would want to call start the reverse when the animation ends, so you'd probably need to put a listener on the animator and check when OnAnimationEnd with the animtor to reverse is called.

I had the Same problem with my views . so I came over this problem with this trick . So We assume we have a view that applying an animate after clicking on it .


          viewLayout.arrow_back.setOnClickListener {arrow ->
            arrow.animate().rotationXBy(50F) // this is a just simple anim not so usefull
                .start()
            arrow.isEnabled = false
        }

I hope it'll Help someone .

I met the same problem, because I animate the view use ViewPropertyAnimator, addView() and removeView() again and again for not creating new view, but a view can be shown once, when you remove the view, you call addview() again, it is no show, but you see the property visibility is visible and animationListener also be called. it is strange.

See the solution I came up with as I had a similar issue with animations inside views in a recycler view, so I had to find a way to reset them:

Trying to reset values from Property Animator to be used in recycler view

Good news in Android O these will be better supported

Do you mean stop a running animation? If so, call clearAnimation() to remove animations from the views that you called startAnimation(); If what you mean is to reset the view to its original appearance after the animation is over, always setFillAfter(false); to the animations.
