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

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) {
    }
});

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 :)

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**


            }
        });

You can also achieve this using Animation.setFillAfter
