J'ai combiné le tiroir de navigation avec la disposition des onglets. Dans cet onglet, la disposition fonctionne correctement pour trois onglets, mais le tiroir de navigation se comporte mal. L'icône du tiroir de navigation a disparu, elle s'ouvre en glissant en ne se fermant pas en glissant. Et aussi les menus dans le tiroir de navigation ne fonctionnent pas.Le tiroir de navigation ne fonctionne pas
