Probleme galerie d'images

Bonjour

j'essaie de créer une galerie d'image d'après le tuto de Mickaël Le Trocquer

J'ai repris le code exactement et j'ai ces erreurs sur le logcat

Pouvez-vous m'indiquer de quoi cela provient

D'autre part dans ce code

gallery.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView parent, View v, int position, long id) {			
				setImage(imgView, mListImages.get(position));
			}
		});

j'ai ce commentaire

AdapterView is a raw type. References to generic type AdapterView<T> should be parameterized
3 quick fixes available
-add type parameters to AdapterView
- infer Generic Type Argument
@Add@SuppressWarning 'Unchecked' to 'onItemclick()'

Que faire ?

Merci pour vos réponses
