What is differene between ScrollView and NestedScrollView

ScrollView :

It is a widget of android. Scroll View for use of scrolling screen
when user need scroll screen because of screen content not show
 in single screen that time developer set scroll view.
In scroll view parent view or layout need necessary. But if developer need
set scroll view on more than one recycler view or list view that time not
smoothly scroll.

It is a widget of android. Nested Scroll View for use of scrolling screen
when user need scroll screen because of screen content not show
 in single screen that time developer set nested scroll view.
In nested scroll view parent view or layout need necessary. But if developer need
set nested scroll view on more than one recycler view or list view that time not
smoothly scroll set enableNested Scroll property of enable nested.
