引发异常的代码：

 @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            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();
            i.putString("id_niveau", id_niveau);
            i.putString("category", catalNavAdapter.getData().get(position)
                    .getAsString("libelle"));// category);
            CNF.setArguments(i);
            TabHolderFragmentActivity.getMainScreenActivity().pushFragments(parentTab, CNF, CNF
                    .getClass().getSimpleName(), true, true);
        }
        setExitPageBoolean(false);
    }

问题来自rtw 8.7及更早版本中的一个小错误（简而言之，传递给监听器的一些参数是错误的。位置正常，视图不是）联系我们对8.7修补程序的支持，或等待包含它的8.7.0.1（应该很快就会提供）
