Android: MapView in CollapsingToolbarLayout

I'm currently trying to install Map View Map View(or a fragment containing a map). I would like to have a parallax effect when scrolls RecyclerView. Unfortunately, he does not appear at all! Even a gray mesh! However, collapsing animation works. I search everywhere, but all I managed to find is ImageViewno other component. So here are my questions:

  • Can I put anything else, except ImageViewin CollapsingToolbarLayout? (The documentation talks about children, so I thought it was possible).
  • If so, is the fragment allowed?
  • Then what am I doing wrong?

Here is my xml:

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

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appBarLayout"
        android:layout_width="match_parent"
        android:layout_height="300dp">

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

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

            <com.google.android.gms.maps.MapView
                android:id="@+id/main_activity_mapview"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:apiKey="AIzaSyA-kEuKT39QK8eG7iYWriFgsvkrZZz6zNo"
                android:clickable="true"
                app:layout_collapseMode="parallax" />

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

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

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

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

And the part where I will return the card. onMapReadynever works.

    if (mMap == null) {

        MapView mapView = (MapView) findViewById(R.id.mapview);
        mapView.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                mMap = googleMap;
                MapsInitializer.initialize(MainActivity.this);
                //...
                // other stuff here
            }
        });

    }

You can use MapView also to display google map.
