在Android中停止ObjectAnimators的AnimatorSet

Question

我试图停止ImageView点击按钮时的动画.我正在使用的动画是AnimatorSet由5组成ObjectAnimators...问题是我无法想象如何从ImageView点击按钮时停止和清除此动画,因为btn.clearAnimation()显然不起作用.

谢谢您的帮助.

Answer 1

如果AnimatorSet添加了侦听器,请确保在取消之前删除侦听器.

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

Answer 2

你应该可以打电话animatorSet.cancel()取消动画.这是一个在动画启动后5秒取消动画的示例:

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);
    }
}
