对于游戏开发中我们可能经常要用到双按屏幕，在Android 1.6以前并没有提供完善的手势识别类，在Android 1.5 SDK中我们可以找到android.view.GestureDetector.OnDoubleTapListener，但是经过测试仍然无法正常工作，不知道什么原因，如果您知道可以联系android123@163.com 共享下。最终我们使用的解决方法如下

     最终我们测试的如下:

public class TouchLayout extends RelativeLayout {  
    public Handler doubleTapHandler = null;  
    protected long lastDown = -1;  
    public final static long DOUBLE_TIME = 500;  
   
 public TouchLayout(Context context) {  
       super(context);  
       
    }  
    public TouchLayout(Context context, AttributeSet attrs) {  
       super(context, attrs);  
       
    }  
    public TouchLayout(Context context, AttributeSet attrs, int defStyle) {  
       super(context, attrs, defStyle);  
        
    }  
     
    public boolean onTouchEvent(MotionEvent event) {  
         this.handleEvent(event);  
         if (event.getAction() == MotionEvent.ACTION_DOWN) {  
            long nowDown = System.currentTimeMillis();  
            if (nowDown - lastDown < DOUBLE_TIME)  
            {  
                  if (doubleTapHandler != null)  
                     doubleTapHandler.sendEmptyMessage(-1);  
            } else {  
               lastDown = nowDown;  
            }  
         }  
         return true;  
      }  
     
     
    protected void handleEvent(MotionEvent event) {  
        switch (event.getAction()) {  
        case MotionEvent.ACTION_DOWN:  
         //Do sth 这里处理即可  
           break;  
        case MotionEvent.ACTION_UP:  
           //Do sth  
           break;  
        }  
     }  
} 
public class TouchLayout extends RelativeLayout {
    public Handler doubleTapHandler = null;

    public final static long DOUBLE_TIME = 500;
 
 public TouchLayout(Context context) {
