滑动拼图，点击可滑动的拼图，那个拼图就消失了
照着视频 快速实现不一样的移动拼图 写下来的程序，写到2-3的时候，我点击可滑动方块，本来应该是和空方块进行交换的，但是却没有进行交换，而本来的方块也消失了，就造成了，我点击空方块旁边有图案的方块之后，空方块还是空的，有图案的方块也消失了。

public int p_x = 0;
/**每个小方块图片的实际位置y*/
public int p_y = 0;
public GameData(int x, int y, Bitmap bm) {
this.x = x;
this.y = y;
this.bm = bm;
this.p_x = x;
this.p_y = y;
}
}
}为什么交换的时候只是图片交换了，原来初始化空白的实际位置不变，导致只能原来图片只能和初始化的空白位置交换。
