Android - how to remove bottom navigation view and toolbar in some fragments if using navigation controller?

If you are using the Navigation Component in Android with a Bottom Navigation View and want to hide the Bottom Navigation View and Toolbar in specific fragments, you can achieve this by adjusting the visibility of these views programmatically.

Here's an example of how you can hide the Bottom Navigation View and Toolbar in specific fragments using the Navigation Component:

  1. Add an ID to your Toolbar and Bottom Navigation View:

    In your layout XML file (e.g., activity_main.xml), make sure to give an ID to your Toolbar and BottomNavigationView:

    <androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent"> <!-- Your other layout elements --> <com.google.android.material.appbar.AppBarLayout android:id="@+id/appBarLayout" android:layout_width="match_parent" android:layout_height="wrap_content"> <androidx.appcompat.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:layout_scrollFlags="scroll|enterAlways" app:popupTheme="@style/AppTheme.PopupOverlay" /> </com.google.android.material.appbar.AppBarLayout> <!-- Your other layout elements --> <com.google.android.material.bottomnavigation.BottomNavigationView android:id="@+id/bottomNavView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" app:menu="@menu/bottom_nav_menu" /> </androidx.coordinatorlayout.widget.CoordinatorLayout>

  2. Handle Visibility in Fragments:

    In your fragment, you can access the Toolbar and BottomNavigationView and adjust their visibility based on your requirements:

    public class YourFragment extends Fragment { private Toolbar toolbar; private BottomNavigationView bottomNavView; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_your, container, false); // Find the views by ID toolbar = view.findViewById(R.id.toolbar); bottomNavView = view.findViewById(R.id.bottomNavView); // Hide Toolbar and BottomNavigationView in this fragment if (toolbar != null) { toolbar.setVisibility(View.GONE); } if (bottomNavView != null) { bottomNavView.setVisibility(View.GONE); } // Your fragment logic return view; } }

    Make sure to set the visibility based on your specific logic. This example hides both the Toolbar and BottomNavigationView in the fragment. You can customize it based on your needs.

By handling the visibility in each fragment, you can control which fragments should show or hide the Toolbar and BottomNavigationView.

Examples

  1. "Android Navigation Component hide BottomNavigationView in certain fragments"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Hide BottomNavigationView in this fragment (activity as AppCompatActivity).findViewById<BottomNavigationView>(R.id.bottomNavigationView).visibility = View.GONE }

    Description: Access the BottomNavigationView from the activity and set its visibility to View.GONE in the onViewCreated method of the fragment.

  2. "Android Navigation Controller hide Toolbar in specific fragment"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Hide Toolbar in this fragment (activity as AppCompatActivity).supportActionBar?.hide() }

    Description: Access the ActionBar from the activity and hide it in the onViewCreated method of the fragment.

  3. "Android Navigation Component remove BottomNavigationView on certain screens"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Remove BottomNavigationView from the NavController graph findNavController().graph.remove(R.id.bottom_navigation_fragment) }

    Description: Remove the specific destination (fragment) associated with the BottomNavigationView from the NavController graph in the onViewCreated method of the fragment.

  4. "Android Navigation Controller hide Toolbar on specific screen"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Hide Toolbar on this specific screen (activity as AppCompatActivity).supportActionBar?.hide() }

    Description: Access the ActionBar from the activity and hide it in the onViewCreated method of the fragment.

  5. "Android Navigation Controller remove BottomNavigationView dynamically"

    Code Implementation:

    // In your activity val navController = findNavController(R.id.nav_host_fragment) navController.addOnDestinationChangedListener { _, destination, _ -> // Remove BottomNavigationView dynamically based on destination if (destination.id == R.id.fragment_to_hide_bottom_nav) { bottomNavigationView.visibility = View.GONE } else { bottomNavigationView.visibility = View.VISIBLE } }

    Description: Use addOnDestinationChangedListener on the NavController to dynamically show or hide the BottomNavigationView based on the current destination.

  6. "Android Navigation Component hide Toolbar and BottomNavigationView programmatically"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Hide Toolbar (activity as AppCompatActivity).supportActionBar?.hide() // Hide BottomNavigationView (activity as AppCompatActivity).findViewById<BottomNavigationView>(R.id.bottomNavigationView).visibility = View.GONE }

    Description: Programmatically hide both the Toolbar and BottomNavigationView in the onViewCreated method of the fragment.

  7. "Android Navigation Controller conditional removal of Toolbar"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Conditional removal of Toolbar based on a condition if (shouldHideToolbar()) { (activity as AppCompatActivity).supportActionBar?.hide() } } private fun shouldHideToolbar(): Boolean { // Add your condition here return true }

    Description: Conditionally hide the Toolbar based on a specific condition in the onViewCreated method of the fragment.

  8. "Android Navigation Controller remove BottomNavigationView from certain fragments"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Remove BottomNavigationView from certain fragments findNavController().addOnDestinationChangedListener { _, destination, _ -> if (destination.id == R.id.fragment_without_bottom_nav) { (activity as AppCompatActivity).findViewById<BottomNavigationView>(R.id.bottomNavigationView).visibility = View.GONE } } }

    Description: Dynamically remove the BottomNavigationView from certain fragments based on the destination.

  9. "Android Navigation Component hide Toolbar and BottomNavigationView conditionally"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Conditional hiding of Toolbar and BottomNavigationView if (shouldHideToolbarAndBottomNav()) { (activity as AppCompatActivity).supportActionBar?.hide() (activity as AppCompatActivity).findViewById<BottomNavigationView>(R.id.bottomNavigationView).visibility = View.GONE } } private fun shouldHideToolbarAndBottomNav(): Boolean { // Add your condition here return true }

    Description: Conditionally hide both the Toolbar and BottomNavigationView based on a specific condition in the onViewCreated method of the fragment.

  10. "Android Navigation Controller hide Toolbar and BottomNavigationView based on user role"

    Code Implementation:

    // In your fragment override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) // Hide Toolbar and BottomNavigationView based on user role val userRole = getUserRole() // Implement your logic to get user role if (userRole == UserRole.ADMIN) { (activity as AppCompatActivity).supportActionBar?.hide() (activity as AppCompatActivity).findViewById<BottomNavigationView>(R.id.bottomNavigationView).visibility = View.GONE } } private fun getUserRole(): UserRole { // Implement your logic to get user role return UserRole.USER }

    Description: Dynamically hide both the Toolbar and BottomNavigationView based on the user's role or a specific condition in the onViewCreated method of the fragment.
