My xml is composed by one constraint layout. Inside this there are 2 buttons and 1 nested scroll view. Inside the ScrollView there are various elements including recycle view. I would like that the recycle view not scroll but scroll only the nested scroll view. I have disabled the scroll of recycle view in this mode
(recyclerView.setNestedScrollingEnabled(false);)
but the problem is that the nested scroll view not scrolling. Can you help me?
I attach the code below.
The code start in this mode :

As i answered in comments
For Someone other facing same problem. This might help.
For some reasons ScrollView doesn't scroll when having ConstraintLayout inside it.
For Workaround we can use LinearLayout or RelativeLayoutinstead of ConstraintLayout inside ScrollView. OR
As OP does put the ConstraintLayout inside Linear or Relative Layout does the trick.
