Side Navigation Drawer Item click not working

Question

PLEASE READ FIRST BEFORE ANYONE MARK IT AS DUPLICATE QUESTION BECAUSE IT IS NOT.

I have used Navigation Drawer, Bottom Navigation bar and a custom Action bar.

Bottom navigation bar and action bar are working fine. navigation drawer also shows menu present under it but the items are not clickable.

I have tried all the answers related to

navigation drawer item click not working

but still my problem has not been solved yet. there is no error in the debug section.

Just put your NavigationView after FrameLayout. Check below code:
