Android中實現雙擊屏幕跳轉

2個類

一個是Activity

另一個是OnDoubleClick事件處理類

/**

public class GameActivity extends Activity {
GameActivityHelper helper;
private GestureDetector gd;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
helper=new GameActivityHelper(this);
helper.init();
setContentView(helper.getGameView());
gd=new GestureDetector(this,new OnDoubleClick());
}
@Override
public boolean onTouchEvent(MotionEvent event) {
return gd.onTouchEvent(event);
}
}

--------------------------------------

import android.view.GestureDetector;
import android.view.MotionEvent;

public class OnDoubleClick extends GestureDetector.SimpleOnGestureListener{
@Override
public boolean onDoubleTap(MotionEvent e) {
//TODO
return true;
}
// @Override
// public boolean onDoubleTapEvent(MotionEvent e) {
// return super.onDoubleTapEvent(e);
// }
}
