Problème KeyListener sur Listview
Bonjour,
Je rencontre un problème actuellement.
J'ai un KeyListener attaché a ma Listview, Mais celui ci n'est pas pris en compte si le nombre d'élément contenu dans la ListView est trop important et alors c'est le comportement par default de la ListView qui est pris en compte.
Auriez vous une idée de la raison d'un tel comportement?
Voici le code du fragment concerné particulierement la partie CreateView
