Androidx scrolling view behavior not working

Question

After switching to androidx the following code stopped working. The TextView below the Toolbar used to scroll with the content, but now it doesn't. I managed to make it work only when I set the same scrollFlags to Toolbar, but I would like to keep that in place. Is there a solution to this besides moving the Toolbar out of AppBarLayout and CoordinatorLayout?

<androidx.coordinatorlayout.widget.CoordinatorLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        <androidx.appcompat.widget.Toolbar
                app:title="Non-scrollable title"
                android:layout_width="wrap_content"
                android:layout_height="?android:attr/actionBarSize"/>

        <TextView
                app:layout_scrollFlags="scroll"
                android:layout_margin="16dp"
                android:textSize="20sp"
                android:text="this should scroll with the content"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>

    </com.google.android.material.appbar.AppBarLayout>

    <androidx.core.widget.NestedScrollView
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

        <!-- some scrollable content here -->

    </androidx.core.widget.NestedScrollView>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

Answer 1

replace attribute old: app:layout_behavior="@string/appbar_scrolling_view_behavior"

new: app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"

and add

implementation 'com.google.android.material:material:1.0.0'
