Answer 1

You should use NestedScrollView instead. However you may need to write your own LayoutManager. Check out this SO Answer for more details

Answer 2

1. You need to use a custom layout manager to use recyclerview inside a scrollview.

2. You can remove the scrollview and make a header item in the vertical recyclerview which contain the horizontal recyclerview.

Also you should not use a recyclerview inside a scrollview. So think the second approach will be better.

Also you can can use Snap-RecyclerView-Utils. It has a linear layout manager for recyclerview inside a scroll view and an adapter which can help you make a header containing you horizontal recyclerview.
