引发异常的代码：
@Override

long id) {
ContentValues niveau = (ContentValues) catalNavAdapter
.getItem(position);
id_niveau = niveau.getAsString(CatalProvider.KEY_ID);
Long niveau_usg = niveau.getAsLong(CatalProvider.KEY_NIVEAU);
RelativeLayout rlyt = (RelativeLayout) view; //!! EXCEPTION IS RAISED HERE
TextView txtLibelle = (TextView) rlyt.getChildAt(0);
Bundle i = new Bundle();
if (niveau_usg > 0) {
String subcategory = txtLibelle.getText().toString();
CatalProdFragment CPF = new CatalProdFragment();
i.putString("id_niveau", id_niveau);
i.putLong("niveau_usg", niveau_usg);
i.putString("subcategory", subcategory);
i.putString("category", extras.getString("category"));
CPF.setArguments(i);
TabHolderFragmentActivity.getMainScreenActivity().pushFragments(parentTab, CPF, CPF
.getClass().getSimpleName(), true, true);
} else {
CatalNavFragment CNF = new CatalNavFragment();
