Android用SurfaceView写一个简单有趣的游戏--《数字组合》之一

最近突然有了一个想法--做一款android的简单游戏练练手，既要实现起来简单（毕竟只有一个人，框架什么的暂且就不用考虑了），又要能够达到对android知识框架的复习和游戏要有可玩性，终于用了几个星期写完了。和大家分享分享体会吧。

      本来打算写一个专栏的。看以后的时间吧。

     首先介绍一下游戏的主要思想和SurfaceView也就是游戏主界面的代码分享，后续部分再更新吧。

     在点击 开始游戏 后，进行组合数字的选择，根据难易程度系统默认选择2和8，选择界面中间显示选择的组合数字，第一个数字表示第一个组合数字，
        即在游戏过程中能被整除的那个数字，第二个数字表示第二个组合数字，即在游戏过程中不能被整除的那个数字。选择结束后开始游戏。
        在游戏准备完成后开始游戏，随机下落一定范围内的数字，判断该数字是否被第一个组合数字整除而不能被第二个数字整除，若是，点击该数字，分数加上对应值，否则分数减去对应值。
        下落数字的范围会随着等级的提升变大。下落速度和数字的产生速度也为随之加快。当分数小于0或错过的正确值大于5时游戏结束！
