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);
}
}
