Can't get items from ListAdapter

I read data from database:

private MyDatabase db;
private Cursor cities;
private ListAdapter cityListAdapter;
private ListView    citiesListView;

db = new MyDatabase(getContext());
cities = db.getCities();

And set an adapter for it:

cityListAdapter = new SimpleCursorAdapter(getContext(),
        android.R.layout.simple_list_item_1, 
        cities, 
        new String[] {"city"}, 
        new int[] {android.R.id.text1},0);

citiesListView.setAdapter(cityListAdapter);

I can see the ListView populated correctly. But when I try to get an item's string, I get a strange string instead: android.database.sqlite.SQLiteCursor@4251fac0

Here's my code for this:

citiesListView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
        String str = cityListAdapter.getItem(position).toString();

        chosenCityTextView.setText(str);
    }
});

Why am I not getting the string that appears in the ListView?
