使用RecyclerView时，常需设置项间分割线。常见方法是设置项根布局右外边距和RecyclerView左外边距，但会使首项与其他项间距不同。而SCommonItemDecoration是最佳方案，支持多种布局管理器和不同方向，给出了使用示例。

When using RecyclerView, we often need set dividers between items. Usually, we set right_margin to the root layout of each item. In this way, you hava to set a left_margin to the RecyclerView to make the list looks symmetric. There's another way to do this. We can customize ItemDecoration and override the getItemOffsets method. Also, set right to the parameter outRect to each item. And add left to the first item. In this way, you will find that the width between the first and other items are not the same.

So this SCommonItemDecoration is the best way. It supports LinearLayoutManager, GridLayoutManager and StaggeredGridLayoutManager, also supports different orientation.

Usage

mRecyclerView.addItemDecoration(

SCommonItemDecoration.builder()

.type(TYPE_1)

.prop(verticalSpace, horizaontalSpace, hasVerticalEdge, hasHorizontalEdge)

.buildType()

.type(TYPE_2)

.prop(verticalSpace, horizaontalSpace, hasVerticalEdge, hasHorizontalEdge)

.buildType()

.build()

);

That's all, enjoy youself.
