No se pueden recibir cadenas de la base de datos de Android Firebase

Quiero obtener el nombre (String) y la ubicación (String) de mi base de datos firebase en una vista de lista de una página de fragmentos de mi aplicación. No da ningún error, pero el nombre y el texto de ubicación simplemente no aparecen en la aplicación. gracias por la ayuda. Creo que hay un problema para obtener las cadenas del servidor de base de fuego.

Firebase hierarchy : FIREBASE -> Events -> XmasParty -> location = Germany
                                                     -> name = XmasParty
