Android - How to combine BottomAppBar + FAB with BottomNavigationView

Combining a BottomAppBar with a FloatingActionButton (FAB) and a BottomNavigationView in an Android app can provide a sleek and user-friendly navigation experience. Here's how you can achieve this setup:

  1. Layout XML: Define your layout XML file (activity_main.xml for example) with a CoordinatorLayout containing a BottomAppBar, a FloatingActionButton, and a BottomNavigationView. Make sure to position them correctly within the layout hierarchy.

    <?xml version="1.0" encoding="utf-8"?> <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"> <!-- Content --> <com.google.android.material.bottomappbar.BottomAppBar android:id="@+id/bottom_app_bar" android:layout_width="match_parent" android:layout_height="wrap_content" app:layout_anchor="@id/content_container" app:layout_anchorGravity="bottom" app:fabAlignmentMode="end" /> <com.google.android.material.floatingactionbutton.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" app:srcCompat="@drawable/ic_add" app:layout_anchor="@id/bottom_app_bar" /> <com.google.android.material.bottomnavigation.BottomNavigationView android:id="@+id/bottom_navigation" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" app:menu="@menu/bottom_navigation_menu" /> </androidx.coordinatorlayout.widget.CoordinatorLayout>

  2. Menu Resource: Create a menu XML resource file (bottom_navigation_menu.xml) for your BottomNavigationView with the desired menu items.

    <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/navigation_home" android:title="Home" android:icon="@drawable/ic_home" /> <!-- Add more items as needed --> </menu>

  3. Activity Code: In your activity code (MainActivity.java for example), set up the BottomAppBar and BottomNavigationView as needed. You can handle navigation item clicks from the BottomNavigationView.

    import android.os.Bundle; import androidx.appcompat.app.AppCompatActivity; import com.google.android.material.bottomnavigation.BottomNavigationView; import com.google.android.material.bottomappbar.BottomAppBar; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); BottomAppBar bottomAppBar = findViewById(R.id.bottom_app_bar); setSupportActionBar(bottomAppBar); BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation); bottomNavigationView.setOnNavigationItemSelectedListener(item -> { switch (item.getItemId()) { case R.id.navigation_home: // Handle navigation home click return true; // Handle other navigation item clicks } return false; }); } }

This setup provides a cohesive user interface with a BottomAppBar, a FloatingActionButton, and a BottomNavigationView, allowing users to navigate through your app efficiently. Make sure to customize the layout and behavior according to your app's requirements.
