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);
	}
    
    
}
