在Android中停止ObjectAnimators的AnimatorSet [英] Stop AnimatorSet of ObjectAnimators in Android

问题描述

我试图在单击按钮时停止 ImageView 的动画。我正在使用的动画是一个 AnimatorSet ，它由5个 ObjectAnimators 组成。问题是我无法弄清楚当单击按钮 btn.clearAnimation（）时，如何停止并从 ImageView 清除此动画？

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.

谢谢您的帮助。

推荐答案

您应该可以调用 animatorSet.cancel（）来取消动画。下面是一个在动画播放5秒后取消动画的示例：

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);
    }
}
