Android : How to access a selected value from custom spinner in android

What i am having :: I have a custom spinner I am able to set the custom spinner with two textviews

What i am trying to do:: I want to access the selected values from the custom spinner from textviews

---

Code in my spinner adapter::

public class AdpSearchCitySpinner extends BaseAdapter {

    Context mContext;
    ArrayList<LinkedHashMap<Integer, String>> city;

    public AdpSearchCitySpinner(Context context, ArrayList<LinkedHashMap<Integer, String>> _listCollection) {
        super();
        this.mContext = context;
        city=_listCollection;
    }

    @Override
    public int getCount() {
        return city.size();
    }

    @Override
    public Object getItem(int position) {
        return city.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        LinkedHashMap<Integer, String> mapCollection=city.get(position);

        String value = "";
        int key = 0 ;

        for (Entry<Integer, String> entry : mapCollection.entrySet()) {
            key = entry.getKey();
            value = entry.getValue();
        }

        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        View row = inflater.inflate(R.layout.adp_search_city_spinner, parent, false);
        TextView cityName = (TextView) row.findViewById(R.id.city_id);
        cityName.setText(String.valueOf(key));
        TextView cityId = (TextView) row.findViewById(R.id.city_name);
        cityId.setText(value);

        return row;
    }   
}

Code in my fragment::

private void setMessengerObj() {

        try {
            //Retrieve the selected values from spinner adapter
            View spinnerAdp =spnSearchByCity.getSelectedView();
            TextView city_name = (TextView) spinnerAdp.findViewById(R.id.city_name);
            TextView city_id = (TextView) spinnerAdp.findViewById(R.id.city_id);
            //Set the messenger object
            messengerObj.put("city_name", city_name.getText().toString());
            messengerObj.put("city_id", city_id.getText().toString());
            Log.d("", "");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            Log.d("--Error-Thrown--", e.toString());
        }
    }

The line

TextView city_name = (TextView) spinnerAdp.findViewById(R.id.city_name);

is throwing a null pointer exception
