Swippable behavior of tabs not working when using NestedScrollView?

Question

I am trying to learn Material Design, I am trying to make a layout like current layout of Whatsapp home screen

It all works fine i had set up my tabs and also able to make swipe layout in tabs, now when i tried to make AppBarLayout exit the screen along with content when scroll, so that my content gets some more height while scrolling and my toolbar hide while scrolling. For that,

I had included NestedScrollView as parent of my content_main layout, And i included that content_main inside my activity_main but due to use of nested scroll view the swipe behavior of tabs are gone.

Currently its working like this but tabs are not swippable now, tabs are working properly when i clicked them.

What can be the issue?

content_main.xml
