End animation event android

Question

I have a fadeout animation in a view (which is inside a fragment), and everytime the animation happens, after it finishes the view redraws itself again. I found a work around doing view.SetVisibility(View.GONE) . But it doesn't wait for the animation to finish. I would like to execute this setVisibility code only after the animation has finished. What is the best way to do that?

Answer 1

Functionally the same as the accepted answer but in a much more concise way:

                           /* Add/Remove any animation parameter */
theView.animate().alpha(0).setDuration(2000).withEndAction(new Runnable() {
    @Override
        public void run() {
            theView.setVisibility(View.GONE);
        }
    });

Enjoy :)

You can add Animation listener to your animation object like

anim.setAnimationListener(new Animation.AnimationListener(){
    @Override
    public void onAnimationStart(Animation arg0) {
    }           
    @Override
    public void onAnimationRepeat(Animation arg0) {
    }           
    @Override
    public void onAnimationEnd(Animation arg0) {
    }
});

You can also achieve this using Animation.setFillAfter

Answer 4

Simply take your animation object and add animation listener to it. Here is the example code :

rotateAnimation.setAnimationListener(new AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationRepeat(Animation animation) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                // TODO Auto-generated method stub

**// WRITE HERE WHATEVER YOU WANT ON THE COMPLETION OF THE ANIMATION**


            }
        });

Example for Kotlin

var fadeOutImage = findViewById<ImageView>(R.id.fade_out_Image)
    val fadeOutAnimation = R.anim.fade_out_animation
    val animation = AnimationUtils.loadAnimation(this, fadeOutAnimation)
    fadeOutImage.startAnimation(animation)

    animation.setAnimationListener(object : Animation.AnimationListener {
        override fun onAnimationStart(p0: Animation?) {
//                not implemented
        }

        override fun onAnimationRepeat(p0: Animation?) {
//                not implemented
        }

        override fun onAnimationEnd(p0: Animation?) {
            fadeOutImage.visibility = View.INVISIBLE
        }
    })
