End animation event android

I have a fadeout animation in a view (which is inside a fragment), and everytime the animation happens, after it finishes the vi开发者_如何学JAVAew 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?


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


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
        }
    })
