android5.0之RecyclerView

早就听说RecyclerView有多少多少XX
但是直到今天才开始尝试使用它，惭愧惭愧



包括：
1，分割线装饰（DividerGridItemDecoration & DividerItemDecoration）
2，自定义动画（ScaleInOutItemAnimator等）
3，Item点击和长按事件
4，动态添加删除Item
5，自定义ActionBar风格

注意：瀑布流效果需要Item的高度都不一致，这样才能看出来。
动态添加删除Item时分割线会有点小问题，如果很介意，建议不要使用装饰（Decoration）来实现分割线，而是使用Item的padding或margin

很简单直接上代码
