Question

So, I have an ArrayList that has name and id

Gil 232
Asty 2423 and so on. 

To use it in the spinner, what I did was to create two separate String Arraylists. One containing the names and the other the corresponding ids. So, that once the user is selected, I will get the corresponding id from the position.

I am not sure how to do that last part. As to, how to get the position?> parent.getItemAtPosition(pos).toString();
This gives me the name again and not the position of the name in the ArrayList which I can use to retrieve the ID from the other list. How to do it? And, is their a better way to go about it?

Answer 1

public class User {
    public int id;
    public String name;
}

public class CustomAdapter extends ArrayAdapter<Data> implements Spinner
                                                      .OnItemSelectedListener {
    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        LayoutInflater inflater = getLayoutInflater();
        View view = inflater.inflate(android.R.layout.simple_spinner_item,
                        parent, false);
        Data data = getItem(position);
        // Do something with data and view here
        return view;
    }

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, 
                                                int position, long arg4) {
        Data data = getItem(position);
        // Do something with data here
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
    }

}

Then create an ArrayList<Data> and use with your CustomAdapter.
