Any type of map is not showed

[franrc]

Hi!

When I add a google maps view o mapbox view, this is not showed at all, although the map is fully functional.

How can solve this?

Here is my layout

<com.github.florent37.diagonallayout.DiagonalLayout
android:layout_width="match_parent"
android:layout_height="330dp"
app:diagonal_position="top"
app:diagonal_direction="right"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent">

                <com.mapbox.mapboxsdk.maps.MapView
                    android:id="@+id/mapView"
                    android:layout_width="match_parent"
                    android:layout_height="330dp"
                    app:mapbox_styleUrl="@string/mapbox_style_mapbox_streets"
                    app:mapbox_cameraTilt="60"
                    app:mapbox_cameraZoom="12"/>

</com.github.florent37.diagonallayout.DiagonalLayout>
