Android 震动示例--心跳效果

正在开发第二个游戏，计时就要结束的时候，为了营造紧张的气氛，会利用手机自身的震动模拟心跳效果，其实这个心跳效果做起来真的非常的简单。所以直接上代码了（注意模拟器是模拟不了震动的，得真机测试哦）：
程序效果：

 package com.ray.test;  
   
 import android.app.Activity;  
 import android.os.Bundle;  
 import android.os.Vibrator;  
 import android.view.MotionEvent;  
   
 public class TestViberation extends Activity {  
     Vibrator vibrator;  
     /** Called when the activity is first created. */  
     @Override  
     public void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  
     }  
    
     @Override  
     protected void onStop() {  
         if(null!=vibrator){  
             vibrator.cancel();  
         }  
         super.onStop();  
     }  
   
     @Override  
     public boolean onTouchEvent(MotionEvent event) {  
   
         if(event.getAction() == MotionEvent.ACTION_DOWN){  
              vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);  
              long[] pattern = {800, 50, 400, 30}; // OFF/ON/OFF/ON...  
              vibrator.vibrate(pattern, 2);//-1不重复，非-1为从pattern的指定下标开始重复  
         }  
         return super.onTouchEvent(event);  
     }  
       
       
 }
