Add app bar scrolling view behavior to multiple views in CoordinatorLayout

This is a sticky header put in the middle between Toolbar and RecyclerView:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_anchor="@+id/app_bar_layout"
    app:layout_anchorGravity="center|bottom"
    android:text="Shuffle Play"/>

To avoid overlaping with the Toolbar you can set different heights to AppBarLayout and CollapsingToolbarLayout:

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="210dip"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        android:fitsSystemWindows="true"
        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleMarginStart="48dp"
        app:expandedTitleMarginBottom="30dp"
        app:expandedTitleMarginEnd="64dp">

        <ImageView
            android:id="@+id/backdrop"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin" />
    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>


<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="@dimen/slide_handle_height"
    android:scrollbars="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_anchor="@id/appbar"
    app:layout_anchorGravity="center|bottom"
    android:text="Shuffle Play"/>
</android.support.design.widget.CoordinatorLayout>

Also, you can set a height to the Toolbarbut will need to make a custom title with a custom behaviour like this proyect CoordinatorLayoutExample. I made it with a custom title without behavior:

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        android:fitsSystemWindows="true"
        app:collapsedTitleTextAppearance="@style/TransparentText"
        app:expandedTitleTextAppearance="@style/TransparentText"
        app:contentScrim="?attr/colorPrimary">

        <ImageView
            android:id="@+id/backdrop"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_height="80dp"
            android:layout_width="match_parent"
            android:minHeight="?attr/actionBarSize"
            android:gravity="top"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin" >
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Title"
                android:textSize="20sp"
                android:textColor="@android:color/white"/>
        </android.support.v7.widget.Toolbar>
    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>


<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="@dimen/slide_handle_height"
    android:scrollbars="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_anchor="@id/appbar"
    app:layout_anchorGravity="center|bottom"
    android:text="Shuffle Play"/>
</android.support.design.widget.CoordinatorLayout>

Styles:

<style name="TransparentText" parent="@android:style/TextAppearance">
    <item name="android:textColor">#00000000</item>
</style>

You don't need a workaround or something strange. This behaviour is supported by the library. Just replace your LinearLayout by this and put it below the RecyclerView:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center">

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="15dp"
            android:text="Button text"/>

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

Also you will need to put this in your RecyclerView to show it behind the LinearLayout:

    android:paddingTop="30dp"
    android:clipToPadding="false"

This is how it would look like:

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

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar_layout"
    android:layout_width="match_parent"
    android:layout_height="@dimen/collapsible_app_bar_height"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/gradient_banner"
        app:contentScrim="@color/background_content_frame"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
            android:id="@+id/image_header"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/some_image"
            app:layout_collapseMode="parallax"/>

        <android.support.v7.widget.Toolbar
            android:id="@+id/collapsible_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:layout_collapseMode="pin"/>

    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="@dimen/slide_handle_height"
    android:scrollbars="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:paddingTop="30dp"
    android:clipToPadding="false"/>

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:gravity="center">

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="15dp"
            android:text="Button text"/>

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

</android.support.design.widget.CoordinatorLayout>

This is not a nice design, but it is a solution. You can put a nicer Layout inside the LinearLayout to make it like Spotify.
