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


        @Override

        // TODO Auto-generated method stub
        }

        @Override

            }
        }

        @Override

            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;
