Je dois vérifier tous les case à onViewCreated() quand je application du déjeuner, mais avec ce codecase à cocher dans onViewCreated() dinamically
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
lv = (ListView)getView().findViewById(R.id.listview);
ck=(CheckBox)getView().findViewById(R.id.chk_box);
displayPlanetList();
CheckBox chBox;
for (int i = 0; i < lv.getCount(); i++) {
view = lv.getAdapter().getView(i, null, null);
chBox = (CheckBox) view.findViewById(R.id.chk_box);
chBox.setChecked(true);
}
plAdapter.notifyDataSetChanged();
}
cases sont désélectionnées.
Je ne sais pas pourquoi.
Je vous montre mon code!
