android游戏开发---06---五子棋（使用的是SurfaceView）

首先说明：这个五子棋使用的是SurfaceView，实际上并不好，因为这个本应该使用View类会更加合适的。但是我为了练习使用SurfaceView，所以才用了它。

SurfaceView和View那个更合适，可以看你开发的程序的性质。总结来说如下：（摘自别人博客中的一段话）

主要就是判断胜利的方式的算法，其实，我也知道，五子棋最好是用数组来存储。这样代码和运行效率是最高的，可我当时不知道怎么就非得使用list，估计脑门被加了。无所谓了，可能是因为贪食蛇也是用的list存储的，所以就很自然的用了list.有兴趣的可以自己试一试那个数组存储的，我猜一定比我这个简单，易懂。自认为自己写的代码的架构还有待提升。所以最近在狠看设计模式，学习一下人家写的代码的质量和扩展性。

好了，想下代码的，去我的资源下代码吧。
