A Spinner, similar to ListView, RecyclerView, etc., is an "adapter backed" View. That is, it gets the items to be displayed from an Adapter.

When you set the entries to be shown using android:entries="@array/operators, Spinner internally creates an Adapter with the supplied array items. This simple solution, however, doesn't support complex objects.

For your use case, you'll have to create a custom Adapter for your Spinner.

public class Operator {
    String name;
    String code;

    public String toString() {
        return name;

final List<Operator> operators = new ArrayList(7);
operators.add(new Operator("Select operator", null));
operators.add(new Operator("Aircel", "AC"));
operators.add(new Operator("Airtel", "AC"));

Next, set the adapter on your spinner:

final ArrayAdapter<String> operatorsAdapter = new ArrayAdapter<>(context, android.R.layout.simple_dropdown_item_1line, operators);

That's it. Now if you want to listen to user's selections, add a listener to your Spinner by:

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        final Operator selectedOperator = operatorsAdapter.getItem(position);
        final String selectedOperatorCode = selectedOperator.code;
        // TODO: Send the selected operator to the server.

    public void onNothingSelected(AdapterView<?> parent) {
