android小游戏 飞机躲子弹

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，

 public class GameView extends SurfaceView implements SurfaceHolder.Callback{

     private boolean threadFlag;
     private int view_width;
     private int view_height;
     private int plane_x;
     private int plane_y;
     private boolean isLive;
     private boolean isBao;
     private int speed;
     private int time;
     private int time1;
     private Date startTime;
     private Date endTime;
     private SurfaceHolder surfaceHolder;
     private Canvas canvas;
     private String TAG = "提示";
     private Bitmap bgBitmap ;
     private Bitmap planeBitmap;
     private Bitmap[] baoBitmaps;
     private Bullet bullet;
     private Plane plane;
     private Context context;
     private SharedPreferences preferences;
     private SharedPreferences.Editor editor;

     ArrayList<Bullet> bullets = new ArrayList<Bullet>();

     public GameView(Context context,int speed) {
         super(context);
         surfaceHolder = this.getHolder();
         surfaceHolder.addCallback(this);
         this.context = context;
         this.speed = speed;

         //System.out.println(getWidth());

         // TODO Auto-generated constructor stub
     }

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。
