首先，定义一个rotate的animation：

?在code里面，实例化一个freshThrad去画animation。点击stop的时候，call freshThrad.interrupt();将此时wait的freshThrad唤醒，调用imagview的clearAnimation方法，停止动画。
package com.animation.test;import android.app.Activity;import android.graphics.drawable.AnimationDrawable;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.view.animation.RotateAnimation;import android.view.animation.Animation.AnimationListener;import android.widget.Button;import android.widget.ImageView;public class AnimationTest extends Activity implements OnClickListener{private ImageView icon;    private Animation animation;    private Button btStop;    private Button btStart;    private boolean runFlag = true;    private MyThread freshThrad;    private final static int START_ANIMATION = 100;    private final static int STOP_ANIMATION = 101;    Handler mHandler = new Handler(){@Overridepublic void handleMessage(Message msg) {// TODO Auto-generated method stubsuper.handleMessage(msg);switch(msg.what){case STOP_ANIMATION:icon.clearAnimation();break;case START_ANIMATION:icon.startAnimation(animation);break;}}        };    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        icon = (ImageView)findViewById(R.id.icon);    btStop = (Button) findViewById(R.id.stop);    btStart = (Button) findViewById(R.id.start);        btStop.setOnClickListener(this);        btStart.setOnClickListener(this);        showAnimation();        icon.setOnClickListener(this);    }@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch(v.getId()){case R.id.icon:        icon.startAnimation(animation);break;case R.id.stop:freshThrad.interrupt();break;case R.id.start:showAnimation();break;}}private void showAnimation(){       animation = AnimationUtils.loadAnimation(this, R.anim.rotate_animation);       animation.setAnimationListener(new AnimationListener(){@Overridepublic void onAnimationEnd(Animation animation) {// TODO Auto-generated method stubicon.startAnimation(animation);}@Overridepublic void onAnimationRepeat(Animation animation) {// TODO Auto-generated method stub}@Overridepublic void onAnimationStart(Animation animation) {// TODO Auto-generated method stub}                });       freshThrad = new MyThread();       freshThrad.start();}class MyThread extends Thread {@Overridepublic synchronized void run() {// TODO Auto-generated method stubMessage msg1 = new Message();msg1.what = START_ANIMATION;mHandler.sendMessage(msg1);try {this.wait();} catch (InterruptedException e) {// TODO Auto-generated catch blockLog.d("debug", "stop therad");Message msg2 = new Message();msg2.what = STOP_ANIMATION;mHandler.sendMessage(msg2);e.printStackTrace();}}}}
?电击start之后，重新起thread开始动画。
