1. 添加依赖：compile'com.android.support:recyclerview-v7:23.1.1'，也可以直接添加高版本的design包，会自动添加recyclerView包。
2. 在xml布局文件中引用RecyclerView
3. 继承RecyclerView.Adapter<RecyclerView.ViewHolder>构造RecyclerView的数据适配器
4. 在Activity中给RecyclerView设置布局管理器（三种布局管理器分别是LinearLayoutManager，GridLayoutManager以及StaggeredGridLayoutManager）
5. 封装item的点击事件以及长按事件
6. 建议将点击事件写在自定义ViewHolder中，要想获得点击item的位置一定要使用getLayoutPosition方法来获得。
注：RecyclerView有一个致命的缺点，每个item之间Google没有实现Divider的设定，解决方案有：
1 设置maigin属性。
2 实现RecyclerView.ItemDecoration：一般可从github上找已做好的框架
3 使用CardView进行item布局，且有卡片的视觉效果
