Uso de fragmentos del cajón de navegación para superponer la actividad

Tengo problemas para poner un fragmento encima de mi actividad actual. Lo que estoy tratando de lograr es la siguiente: Abrir la aplicación -> mapView se crea -> se crea el cajón de navegación -> botón en el cajón de navegación abre un nuevo fragmento por encima de mapView (mientras mapView no es visible). Lo que está ocurriendo es el diseño del fragmento que se está mostrando, pero el espacio en blanco del diseño es transparente y todavía puedo usar el mapa. Aquí está mi código:

MainActivity.java

Si lo entiendo correctamente, lo que está ocurriendo es que los espacios en blanco de su Fragment más superior no capturan eventos de clics. Para resolver esto, necesitas hacer que la raíz ViewGroup de la parte superior más Fragment haga clic. Si el segundo Fragment que se agrega ocupa la totalidad o la mayor parte de la pantalla, es mejor llamar a remove() lugar de add() en su FragmentTransaction para evitar este problema completamente.
