An example of a recyclerview nested recyclerview
最近项目中用到了两个RecyclerView嵌套的布局，即RecyclerView的item也是RecyclerView，其中遇到了两个比较典型的问题：1、当item的方向是垂直方向时，父RecyclerView首次加载会出现位移；2、当item的方向是水平方向时，父RecyclerView上下滑动之后，子RecyclerView位置会还原，本文主要解决以上两个问题。我们先来瞄一眼这两个问题的效果图：
来瞄一眼解决问题后的效果图：
int offset = recyclerView.computeHorizontalScrollOffset();
if (offset > 0 && mItemWidth > 0) {
mEntity.scrollOffset = mItemWidth - offset % mItemWidth + mEntity.scrollPosition * mItemMargin;
}
这段 如果 offset 是0(回到初始位置),那么offset永远不会赋值了，每次回到初始位置都是错的。
