问题是在您的
onCreateView名称来引用它。findViewById（）@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
/* pour creer le fragment*/
View x = inflater.inflate(R.layout.les_agences, container, false);
les_agence_tv_item_adresse = (TextView) x.findViewById(R.id.les_agence_tv_item_adresse);
les_agence_tv_item_nom = (TextView) x.findViewById(R.id.les_agence_tv_item_adresse);
les_agences_iv_item_image = (ImageView) x.findViewById(R.id.les_agences_iv_item_image);
return x;
}
你得到了android.os.NetworkOnMainThreadException？Networkmain True 100/100请使用我不了解你Brahimce我正试图帮助你但我不了解你如果有错误，你需要指定错误的位置，或显示stacktrace（logcat）。@Brahimce所以发布stacktraceSame问题@Fondesa@Brahimce张贴日志
