        app:tabSelectedTextColor="@color/color_secondary"
        app:tabTextColor="@color/color_secondary" />

    <androidx.viewpager2.widget.ViewPager2

        app:layout_constraintTop_toBottomOf="@+id/tab_layout">

    </androidx.viewpager2.widget.ViewPager2>

</androidx.constraintlayout.widget.ConstraintLayout>

and here is what it looks like

The issue is because of CoordinatorLayout

Solution 1: Add

android:clipToPadding="false"
android:clipChildren="false"

in CoordinatorLayout

Solution 2: Make CoordinatorLayout as parent layout and put all child layout in it.

Solution 3:

In view_pager_2 add

            android:layout_marginBottom="?actionBarSize"

Solution 4: Add this line to your fab

android:elevation="10dp"
