MovieAdapter adapter = new MovieAdapter(mContext, R.layout.list_movie, listItems);
			movieList.setAdapter(adapter);

(mon listItems est rempli dans le asynctask class)

Le probleme est que l'application crashe a

MovieAdapter adapter = new MovieAdapter(mContext, R.layout.list_movie, listItems);

Je pense que j'ai mal fait quelque chose dans ma class Adapter mais je ne trouve pas quoi ?

Juste ici

Quelqu'un pourrait il me conseiller ?
J'ai lus plusieurs tuto et je vois vraiment pas ce qu'il ne va pas : /
