How do i make Recyclerview appear on top of mapview

Issue

I have a recycler view which appears when users enter something on a textbox in my Android app. I also have a mapview just below the textbox but when the recycler view appears it goes behind the mapview. I want the recycler view to appear on top of the mapview.

</RelativeLayout>

Solution

Views which placed first in RelativeLayout ViewGroup will draw first on UI, so interchange the order of your views can solve your problem.

<RelativeLayout android:layout_width="match_parent"
android:layout_height="wrap_content">

<com.mapbox.mapboxsdk.maps.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_marginTop="120dp"
    android:layout_gravity="center_horizontal|bottom"
    android:layout_height="240dp" />

<android.support.v7.widget.RecyclerView
    android:id="@+id/myrecyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_marginTop="90dp"
    android:layout_marginStart="20dp"
    android:layout_marginLeft="20dp"
    android:scrollbars="vertical" />
</RelativeLayout>
