ScrollView或者RecyclerView1 嵌套RecyclerView2 ，
进入页面自动跳转到recyclerView2上面页面会自动滚动
貌似是RecyclerView 自动获得了焦点

解决办法：

内部Recyclerview去除焦点，父布局里获得焦点。

recyclerview.setFocusableInTouchMode(false);
recyclerview.requestFocus();

在代码里面让处于ScrollView或者RecyclerView1 顶端的某个控件获得焦点即可
比如顶部的一个textview

tv_goodsName.setFocusableInTouchMode(true);  
tv_goodsName.requestFocus();

内部的Recyclerview加

android:overScrollMode="never"

父布局覆盖子VIew获取焦点：

android:descendantFocusability="blocksDescendants"
