Answer 1

I had the same problem, and I fixed it the following way.

Add android:descendantFocusability="blocksDescendants" to the Linear Layout which is the only child of the Nested Scroll View.

This allows the Nested Scroll View to start from the top with minimal change to code.

Answer 2

It is a problem about focus. Try :

findViewById(R.id.recycler_view).setFocusable(false); findViewById(R.id.temp).requestFocus();
