Stop AnimatorSet of ObjectAnimators in Android

Question

Im trying to stop the animation of an ImageView when a button is clicked. The animation I am using is an AnimatorSet consisting of 5 ObjectAnimators... The problem is that I can't figure how to stop and clear this animation from the ImageView when the button is clicked as btn.clearAnimation() obviously doesn't work.

Thank you for your help.

You should be able to call animatorSet.cancel() to cancel the animation. Here's an example that cancels the animation 5 seconds after it starts:

package com.example.myapp2;

import android.animation.Animator;
import android.animation.AnimatorSet;
import android.animation.ObjectAnimator;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.List;

public class MyActivity extends Activity {
    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TextView tv = (TextView) findViewById(R.id.hello_world);

        List<Animator> animations = new ArrayList<Animator>();

        animations.add(ObjectAnimator.ofInt(tv, "left", 100, 1000).setDuration(10000));
        animations.add(ObjectAnimator.ofFloat(tv, "textSize", 10, 50).setDuration(10000));

        final AnimatorSet animatorSet = new AnimatorSet();
        animatorSet.playTogether(animations);
        animatorSet.start();

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                animatorSet.cancel();
            }
        }, 5000);
    }
}

If you had AnimatorSet listeners added, make sure you remove the listeners before cancel.

animatorSet.removeAllListeners();
animatorSet.end();
animatorSet.cancel();

Thats actually a really important fact. – Eydie

There is no need for end() as cancel will call it automatically. There would be a difference if you removed the listeners after the cancel as you will receive onAnimationCancel first and afterwards onAnimationEnd – Pregnancy
