So, you think that you know how to use Snackbar and FAB? Check one more time if you are up to date with guidelines!

Maybe you got used to using Snackbar on views with List and Floating Action Button. You wrapped everything with CooridnatorLayout and watched shiny animation where FAB was moved up when Snackbar was shown. This looked good, and you were happy. But not anymore!

Some time ago Google changed how Snackbar and FAB should behave together. Now Snacbar should be shown above FAB!

You can read more about it here:

How to achieve it? It’s still easy. Instead of CoordinatorLayout wrap everything with ConstraintLayout and set setAnchorView for Snackbar.

<androidx.constraintlayout.widget.ConstraintLayout
    android:id="@+id/rootLayout"
    android:layout_height="match_parent"
    android:layout_width="match_parent">
    <include
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        layout="@layout/recycler_view_fragment" />
    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fabButton"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

Snackbar.make(rootLayout, TEXT_TO_SHOWN, DURATION_TIME) .setAnchorView(fabButton)

Now you are ready to use Snackbar with Floating Action Button according to Google Material guidelines.

See you on The Code Side!
All the best,
