You have to set host navigation like below xml:

Setup With Navigation Controller :

NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager().findFragmentById(R.id.navigation_host_fragment);
NavigationUI.setupWithNavController(bottomNavigationView, navHostFragment.getNavController());

menu_bottom_navigation.xml :

nav_graph.xml :

By setting up the same id of "nav_graph" to "menu_bottom_navigation" will handle the click of bottom navigation.

You can handle back action using popUpTo property in action tag.
