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());
