I have made an app with bottom navigation view with Promo, Store, Reward, Coupon and Account tabs when I am changing from Coupon fragment to any other fragment, the bottom navigati

Solution 1:

It turns out that if you are using a coordinator layout and viewpager inside a fragment, you will notice that the viewpager extends the screen a bit. Just disable the scroll features of the coordinator layout inside the fragment and you will notice the bottom bar doesn't get shrunk. Weird I know, but it works.

Solution 2:

I add android:fitsSystemWindows="false" in CoordinatorLayout and it worked

Solution 3:

Find android:fitsSystemWindows="true" in your fragment xml and remove this line or change it to android:fitsSystemWindows="false". Your problem will be solved.
