[SOLVED] How to hide the bottom navigation bar in certain fragments?

How to hide the bottom navigation bar in certain fragments?

I have An activity with a navGraph and a bottom Navigation bar with 2 menu items. My problem is that My Bottom Navigation Bar appears everywhere, detailFragment, aboutFragment, signInFragment and so on.


        val navController = this.findNavController(R.id.myNavHostFragment)

        val appBarConfiguration = AppBarConfiguration.Builder(
            R.id.contactsFragment,
            R.id.profileFragment
        ).build()

        NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration)

        val navView: BottomNavigationView = findViewById(R.id.nav_view)
        NavigationUI.setupWithNavController(navView, navController)

How do i Limit it to just show on the 2 fragments on my menu Item?

This is how I solved It

    navController.addOnDestinationChangedListener{ _, nd: NavDestination, _->
        if(nd.id == R.id.contactsFragment || nd.id == R.id.profileFragment){
            navView.visibility = View.VISIBLE
        }else{
            navView.visibility = View.GONE
        }

Solution

For your fragment where it should be visible

navView.visibility = View.VISIBLE

Where it shouldn't be visible

navView.visibility = View.GONE
