In Nested Scroll View How to Scrolling pdf view

Question

enter code hereMy root layout is nested scroll view inside nested scroll view create viewpager for changes pdf left to right, or right to left it works properly but when scroll pdf up down for change pdf view so that not work properly.

What I want:- I want to when click next and previous arrow so pdf are change and when scroll up down so change pdf inside content

my code flow is like (kotlin):- (1) create single item design in design i took barteksc pdf view. (2) create Adapter for class,model class for pdf view (3) set adapter in viewpager

barteksc:android-pdf-viewer:2.8.2 I used this dependency

Note:- without nested scroll view it will work perfect but I want with scroll view.

Thanks.enter image description here
