android小游戏飞机躲子弹 _android

【android小游戏飞机躲子弹】一万年来谁著史，三千里外欲封侯。这篇文章主要讲述android小游戏飞机躲子弹相关的知识，希望能为你提供帮助。
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。

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{ 2 3 4private boolean threadFlag; 5private int view_width; 6private int view_height; 7private int plane_x; 8private int plane_y;

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。
