recycler_menu.setHasFixedSize(true);

Bonjour à tous j'ai un problème dont je n'arrive pas à identifier la source.

Merci de vouloir m'apporter votre aide

c'est l'erreur qui apparaît lorsque j'exécute l'application (on me dit que votre application s'est arrêtée). Dans logcat, lorsque je clique sur la classe affichée, elle me renvoie à l'instruction suivante: recycle_menu.setHasFixedSize (true);

voici le contenu de mon logcat
