FrameLayout рядом с другим

Я использую карту и перекрывающиеся макеты на карте. Я хотел бы установить FrameLayout (frame_layout_visible) рядом с другим FrameLayout (framelayout2). Как мне это сделать? Я не знаю, что я делаю неправильно, но android:layout_toRightOf это не работает.

    <RelativeLayout
    xmlns:android = "http://schemas.android.com/apk/res/android"
    xmlns:tools = "http://schemas.android.com/tools"
    android:layout_width = "match_parent"
    android:layout_height = "match_parent"
    android:animateLayoutChanges = "true"
    tools:context = ".MainActivity$PlaceholderFragment">

    <ActionMenuView
        android:minHeight = "?android:attr/actionBarSize"
        android:background = "?android:attr/colorPrimary"
        android:minWidth = "25px"
        android:layout_width = "match_parent"
        android:layout_height = "wrap_content"
        android:gravity = "top|start"
        
        android:id = "@+id/toolbarMap1" />

    <com.esri.android.map.MapView
        android:layout_width = "match_parent"
        android:layout_height = "match_parent"
        android:id = "@+id/mapView"
        android:src = "@drawable/map"
        android:layout_below = "@id/toolbarMap1"
        android:background = "@android:color/white" />
    <TextView
        android:text = ""
        android:textAppearance = "?android:attr/textAppearanceSmall"
        android:layout_width = "match_parent"
