RecyclerView, Version antérieur à 5.0
Bonsoir les amis ;)
J'essaie d'utiliser le composant RecyclerView dans un projet (de test) ayant pour version minimum antérieure à l'API 21. Mais depuis que j'ai commencé, j'avoue ne pas avancer parce que dès lors que j'ajoute ce composant dans mon fichier layout, Android studio me balance au visage le message suivant (dans la partie preview):

De là, deux questions me passent par la tête :roll:
- La première, est-il possible d'utiliser ce composant dans les versions antérieures à LolliPop?
- La seconde, comment l'utiliser si c'est possible dans les anciennes versions?
Pourriez vous m'aider à passer cette étape avec vos éclaircissements svp?
