L'erreur semble provenir de ce code :

	        private OnItemClickListener ItemListener = new OnItemClickListener(){

					Intent versFidelite = new Intent(getApplicationContext(), FideliteActivity.class);
	    			//versFidelite.putExtras("nomclient",nomclient);
	    			startActivity(versFidelite);

}
Comment puis je remédier à ça?
Merci d'avance
