recyclerview一共有三中布局管理器

用法（与上边对应）

mLayoutManager = new LinearLayoutManager(this);
//垂直方向
mLayoutManager.setOrientation(OrientationHelper.VERTICAL);
//给RecyclerView设置布局管理器
recyclerView_one.setLayoutManager(mLayoutManager);</span>

2.

<span style="font-family:KaiTi_GB2312;font-size:18px;">GridLayoutManager girdLayoutManager=new GridLayoutManager(this,4);
recyclerView_one.setLayoutManager(girdLayoutManager);</span>

3.

<span style="font-family:KaiTi_GB2312;font-size:18px;">StaggeredGridLayoutManager staggeredGridLayoutManager=new   StaggeredGridLayoutManager(2,OrientationHelper.VERTICAL);
