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 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());

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。
