Le message est clair

Citation:

Caused by: java.lang.RuntimeException: Content has view with id attribute 'android.R.id.list' that is not a ListView class

L'id de ta listview est "listView" au lieu de " "@android:id/list" puisque tu utilises un listfragment

Change

Code:

1
2
3
4
<ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/listView" />

par

Code:

1
2
3
4
<ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@id/android:list" />

est-ce parce que j'utilise simple_list_item 1(que je n'avais jamais utilisé) que je dois changer l'id

Même pas. Cet id est préconisé pas Android quand tu utilises ListFragment. Cela permet d'associer directement la ListView que tu as dans le fichier de layout au ListFragment sans l'effort du développeur. Simple n'est ce pas?
Si tu utilisais un fragment simple, tu l'aurais (ListView) géré toi même en commençant par l'inflation bien sûr. Du coup tu ne serais pas obligé d'attribuer cet id.

Christian,
