Android: l'index Z de tiroir de navigation incorrect

Question

J'ai créé un tiroir de navigation "BaseActivity" pour être étendu par plusieurs activités mais quand j'ouvre le tiroir de navigation aucun des éléments de menu ne peut être cliqué, il y a une couche semi-opaque sur ceux qui me suggère l'ordre z dans lequel ils sont chargés est incorrect. Comment ferais-je pour réparer ça?

Si le problème est avec le Z-index comme vous le dites, vous peut le faire toujours sur le dessus en utilisant bringToFront() appeler cette méthode à votre DrawerL ayout ou NavigationView!
