To fix this issue One solution would be to hide the action bar in your specific fragment and create a new ActionBar inside the fragment with your searchview etc. for it. Depending on whether it's a support or normal actionbar it would be something like this in the onCreateView:

code :

val act: MainActivity = activity as MainActivity
    act.supportActionBar?.hide()

Hope that helps The toolbar title is set based on 'label' value inside navigation graph, if you want to do something different with toolbar or BottomAppBar you can add addOnNavigatedListener inside your activity, and based on current destination do something.

code :

findNavController(nav_host_fragment).addOnNavigatedListener { controller, 
 destination ->
 when(destination.id) {
    R.id.destination1 -> {
        //Do something with your toolbar or BottomAppBar
    }
    R.id.destination2 -> {
        //Do something with your toolbar or BottomAppBar
    }

 }
}

Unable to hide the navigation toolbar

I wish did fix the issue. Hiding navigation bar toolbar is different from hiding the navigation bar itself. If you want to hide the toolbar you could try what @Anbu.karthik suggested in the comments. However, if you want to hide the navigation bar, you need to use this instead.

code :

navigationController?.setNavigationBarHidden(true, animated: true)

To fix the issue you can do Try to wrap up host_fragment with NestedScrollView with needed behaviour, like this:

code :

 <androidx.core.widget.NestedScrollView
        android:id="@+id/nestedScrollView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:fitsSystemWindows="true"
        android:transitionGroup="true"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <fragment
            android:id="@+id/nav_host_fragment"
            android:name="androidx.navigation.fragment.NavHostFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:defaultNavHost="true"
            app:navGraph="@navigation/my_nav_host" />
    </androidx.core.widget.NestedScrollView>

How can I use a toolbar in a fragment but not in activity using Jetpack's Navigation

it should still fix some issue You can Listen for navigation events by using OnDestinationChangedListener. For example :

code :

navController.addOnDestinationChangedListener(new NavController.OnDestinationChangedListener() {
   @Override
   public void onDestinationChanged(NavController controller,
       NavDestination destination, Bundle arguments) {

       // getting the current fragment id.
       int currentFragmentID = destination.getId();

       if(currentFragmentID == R.id.fragment_with_toolbar){
        // showing the toolbar
          toolbar.setVisibility(View.VISIBLE);
        } else if(currentFragmentID == R.id.fragment_without_toolbar){
        // hiding the toolbar
          toolbar.setVisibility(View.GONE);
        }
  }
});
