2048源码(核心算法有，缺少几个anctionbar，以后补上)
2048游戏基本上有四部分组成，
1：主activity，包含游戏块的16个方格，上面统计分数的模块
2：底下的gridview，监听上下左右的滑动，进行事件处理，
3：每一个卡片，里面的内容很简单，只有一个text，记录显示的数字
4：Actionbar，是游戏用重新开始，设置等功能(这个在底下可以下载的代码里面还没有实现)
写代码的流程
1：设计游戏的布局，基本是两块，上面是分数模块，下面是gridview
2：代码实现gridview(组合控件)
3：判断处理使gridview可以监听上下左右滑动的事件
4：实现gridview中的card类，里面就是一个textview(组合控件)
5：在gridview中添加card
6：在游戏的初始时随机添加两个数字
7：实现游戏逻辑，进行上下左右的事件处理
8：计分，实现上面分数统计的模块
9：检查游戏结束
10:优化处理，不同数字具有不同的颜色
11:添加动画效果，我的其他文章中有专门对动画进行的阐述
12:添加anctionbar继续进行优化
