Android多线程之控制animation走走停停

首先，定义一个rotate的animation：
Xml代码 
<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"> 
<rotate  
        android:interpolator="@android:anim/accelerate_decelerate_interpolator" 
        android:fromDegrees="0"  
        android:toDegrees="+360"          
        android:pivotX="50%"  
        android:pivotY="50%"      
        android:duration="3000" />   
</set> 
 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，跳用imagview的clearAnimation方法，停止动画。
Java代码 
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(){ 
 
        @Override 
        public void handleMessage(Message msg) { 
            // TODO Auto-generated method stub 
            super.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); 
    } 
    @Override 
    public void onClick(View v) { 
        // TODO Auto-generated method stub 
        switch(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(){ 
         
                @Override 
                public void onAnimationEnd(Animation animation) { 
                    // TODO Auto-generated method stub 
 
                icon.startAnimation(animation);                  
 
                } 
 
                @Override 
                public void onAnimationRepeat(Animation animation) { 
                    // TODO Auto-generated method stub 
                     
                } 
 
                @Override 
                public void onAnimationStart(Animation animation) { 
                    // TODO Auto-generated method stub 
 
                } 
                 
            }); 
           freshThrad = new MyThread(); 
           freshThrad.start(); 
    } 
     
    class MyThread extends Thread { 
        @Override 
        public synchronized void run() { 
            // TODO Auto-generated method stub               
            Message msg1 = new Message(); 
            msg1.what = START_ANIMATION; 
            mHandler.sendMessage(msg1); 
                 
            try { 
                this.wait(); 
            } catch (InterruptedException e) { 
                // TODO Auto-generated catch block 
     
                Log.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。
