Disables the child attach listener so that inflated children with wrap_content heights can pass.

It doesn't seem to work for me.

@muth0mi you need to do other changes as well. This is to just bypass the runtime check in the ViewPager

what all other changes are required to achieve this.

It's been a long time I came up with this. You need to be sure that your inflated children uses wrap_content height.

thanks @safaorhan , it solved my problem.

Glad to hear that!

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
