RecyclerView出現已經有一段時間了，可以通過導入support-v7對其進行使用。

據官方的介紹，該控件用于在有限的窗口中展示大量數據集，

其實這樣功能的控件并不陌生，例如：ListView、GridView。

那么有了ListView、GridView為什么還需要RecyclerView這樣的控件呢？

整體上看RecyclerView架構，提供了一種插拔式的體驗，高度的解耦，異常的靈活，

通過設置它提供的不同LayoutManager，

ItemDecoration , ItemAnimator實現非常炫的效果。

你想要控制其顯示的方式，

請通過布局管理器LayoutManager你想要控制Item間的間隔（可繪制），

請通過ItemDecoration你想要控制Item增刪的動畫，

請通過ItemAnimator你想要控制點擊、長按事件，自己實現。。。。。。。

實現非常簡單

布局文件：

在RecyclerView包裹SwipeRefreshLayout
