Fragment showing nothing when starting my app for first time

Question

I have an app with bottom navigation fragment activity I have placed text views and buttons on my home fragment. further these fragments are placed in a frame layout. when I launch my app my home fragment shows nothing just blank screen it loads everything when I switch between fragments.

Answer 1

because you didn't specify the first fragment to show,

 bottomNavigation.getMenu().findItem(R.id.item).setChecked(true);
