a customized LayoutManager - fade and shrink the head itemView when scrolling.

实现效果

Dribbble 设计：链接
IOS 实现：VegaScroll

代码思路

RecyclerView 最顶部的 itemView，会随着手指滑动实现收缩隐藏与放大显示，并伴随 recycler 的回收与复用。

代码比较简单粗暴，使用自定义的 LayoutManger，内置 SnapHelper。
由于想要在任意时刻都能 snap 到第一个子 View，所以在 LayoutManager 中用了比较讨巧的方法去设定 scroll 的最大值。

使用方法

1. gradle 引入

   compile 'com.stone.vega.library:VegaLayoutManager:1.0.6'
   

2. java 文件中设定 LayoutManager

   recyclerView.setLayoutManager(new VegaLayoutManager());
