MapView under statusbar with CollapsingToolbarLayout

Issue

I have the following XML code:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.design.widget.CollapsingToolbarLayout

            <fragment

                xmlns:map="http://schemas.android.com/apk/res-auto"
                android:layout_width="match_parent"
                android:layout_height="280dp"

                app:layout_collapseMode="parallax"
                app:layout_collapseParallaxMultiplier="0.5"

                map:liteMode="true"
                map:mapType="normal"/>


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

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

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


    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab_pin"
        style="@style/FabStyle"
        app:layout_anchor="@id/abl_header"
        app:layout_anchorGravity="bottom|right|end"/>

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

I would like to have the MapView (fragment here) draw below the status bar as on the picture below:

But instead I have the following result:

But when scrolling, the MapView is correctly drawn below the status bar as shown on the picture below:

And because, this is working when using an ImageView instead of the fragment, I am guessing this is because of a wrong measurement when the fragment is being build.

I would like to know if there is other solution than creating the MapView and creating the Bitmap from the code before injecting the bitmap in an ImageView.

Solution

I figure out how to solve this.

Instead of creating the MapView fragment from the layout file itself. I create the SupportMapFragment and add it to the view using classic Fragment transaction.

In that way, I have a correct rendering.
