android小游戏 飞机躲子弹

Posted 2020-08-23 来一点音乐

最近android老师让每人写一个小东西，因为之前学awt时写过一个java版的飞机躲子弹，所以这次想写成android版的。

 

 

文件直接导入就行http://files.cnblogs.com/files/lolybj/PlaneGame.rar

项目比较简单。主要用了SurfaceView,

只放出主要的类，

  1 public class GameView extends SurfaceView implements SurfaceHolder.Callback{

 10     private boolean isBao;

212     }
213 }

主要的方法，重写surfaceCreated方法，本类的入口。init()方法数据初始化。thread线程方法，绘制坐标移动后的画面。重新onTouchEvent()监听鼠标坐标变化。
