Code that raises exception:

 @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);
    }

ListView layout:

</RelativeLayout>

Listview item layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rlyt_cat_nav_item"

        android:layout_width="wrap_content"
        android:layout_marginLeft="5dp"
        android:textColor="#000000" />

    <TextView
        android:id="@+id/catal_nav_count_libelle"
        style="@style/texte_parent_right"
        android:padding="5dp"

    <TextView
        android:id="@+id/catal_nav_id_niveau"
        style="@style/hidden" />

</RelativeLayout>

Thanks for your help

Answer 1

problem comes from a little bug in rtw 8.7 and older version (to make short, some parameter passed to listener are erroneous. position is ok, view isn't) contact our support for 8.7 hotfix, or wait for 8.7.0.1 that include it (should be available very soon)
