如何通過一個

這是我的全部代碼移動位圖中,,,,如何通過一個

有人能幫助我,,,

public class MainActivity extends Activity { 

@Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
      WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    setContentView(new Panel(this)); 

    } 
} 


class Panel extends SurfaceView implements SurfaceHolder.Callback { 


     private Bitmap[] mBitmap; 
     private ViewThread mThread; 
     public Panel(Context context) { 
      super(context); 
      mBitmap = new Bitmap[4]; 
       mBitmap[0] = BitmapFactory.decodeResource(getResources(), R.drawable.x); 
       mBitmap[1] = BitmapFactory.decodeResource(getResources(), R.drawable.x); 
       mBitmap[2] = BitmapFactory.decodeResource(getResources(), R.drawable.x); 
       mBitmap[3] = BitmapFactory.decodeResource(getResources(), R.drawable.x); 

      getHolder().addCallback(this); 
      mThread = new ViewThread(this); 
     } 

     public void doDraw(Canvas canvas) { 
      canvas.drawColor(Color.BLACK); 

      canvas.drawBitmap(mBitmap[0], 0, 0, null); 
      canvas.drawBitmap(mBitmap[1], 45, 0, null); 
      canvas.drawBitmap(mBitmap[2], 90, 0, null); 
      canvas.drawBitmap(mBitmap[3], 135, 0, null); 


     @Override 
     public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { 
     // TODO Auto-generated method stub 
     } 

     @Override 
     public void surfaceCreated(SurfaceHolder holder) { 
      if (!mThread.isAlive()) { 
       mThread = new ViewThread(this); 
       mThread.setRunning(true); 
       mThread.start(); 
      } 
     } 

     @Override 
     public void surfaceDestroyed(SurfaceHolder holder) { 
      if (mThread.isAlive()) { 
       mThread.setRunning(false); 
      } 
     } 

     @Override 
     public boolean onTouchEvent(MotionEvent event) { 

      mX = (int) event.getX() - mBitmap[0].getWidth()/2; 
      mX = (int) event.getX() - mBitmap[1].getWidth()/2; 
      mX = (int) event.getX() - mBitmap[2].getWidth()/2; 
      mX = (int) event.getX() - mBitmap[3].getWidth()/2; 

      return super.onTouchEvent(event); 

     } 




class ViewThread extends Thread { 
    private Panel mPanel; 
    private SurfaceHolder mHolder; 
    private boolean mRun = false; 

    public ViewThread(Panel panel) { 
     mPanel = panel; 
     mHolder = mPanel.getHolder(); 
    } 

    public void setRunning(boolean run) { 
     mRun = run; 
    } 

    @Override 
    public void run() { 
     Canvas canvas = null; 
      while (mRun) { 
       canvas = mHolder.lockCanvas(); 
       if (canvas != null) { 
        mPanel.doDraw(canvas); 
        mHolder.unlockCanvasAndPost(canvas); 
       } 
      } 
    } 

}

如何移動的位圖到右，由一個位圖我留一個

如果位圖移動則位圖什麼是錯在我的代碼毗鄰

？

如何解決這個我的代碼？

請幫我
