Tiroir de navigation avec des en-têtes / sections

J'aimerais savoir s'il y a une façon de pouvoir ajouter des en-têtes / sections au tiroir de navigation. J'ai réussi à ajouter quelque chose comme ça, mais il est affiché uniquement en haut de la liste, car AddaDeView doit être appelé avant SetAdapter et si j'essaie d'ajouter plus d'éléments après que SetAdapter, ils réécrivent les premiers éléments.

Merci. p>
