  • 0

I’m using the Android compatibility library, targeting Android 2.2. If I use ListFragment With an array adapter, it works fine, but if I use a simpleCursorAdapter, it crashes. Here is the code I have for my ListFragment:

public class Fragment1 extends ListFragment {

    private SQLiteDatabase db;
    private Cursor c;

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
      super.onActivityCreated(savedInstanceState);
      DbManager dbm = new DbManager (getActivity(), "mainDb", null, 3);
      db = dbm.getWritableDatabase();
      c = db.rawQuery("SELECT * FROM navegacion", null);
      c.moveToFirst();

      ListAdapter adapter = new SimpleCursorAdapter( getActivity().getApplicationContext(), R.layout.list_item, c, new String[]{"texto"}, new int []{R.id.mainListText}, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
      setListAdapter(adapter);


    }
 }

DbManager is a class that extends SqliteHelper. I don’t get why it doesn’t work. It used to work with listActivity. I even added the flag to the constructor. When I instantiate this fragment, the device says that the aplication has been interrupted and closes it. Does someone know what I’m doing wrong?

Thank you in Advance.

Edit. Here is the stacktrace from logcat:

    The reason why it is working with ArrayAdapter but not with SimpleCursorAdapter is because SimpleCursorAdapter extends CursorAdapter, and CursorAdapter will not work if your cursor does not contain a column named _id. The values in the _id column should be the values that are bound to the ListView.

    This error has nothing to do with the compatability library.
