Thanks this work for me ,when we want to use viewpager as Book ' pages. There are different kinds of page height. Sometimes , we need to scroll action when page is too long :3 At that time, just wrap your viewpager's item layout with NestedScroll View..

Thanks to @safaorhan

@ChinGyi2019 Glad to hear that it helped!

Our use case was similar, we were showing three items with different heights in ViewPager.

I was getting a calculation of all child views to calculate the one with the biggest height. So I was dynamically changing the height of the ViewPager and triggering a second measurement round
