Android :: How To Get Callback When Spinner Popup Dialog Dismissed?

I have an Android Spinner and I'd like to get a callback when the user selects something from its popup dialog. It seems like
setOnItemClickListener() or setOnItemSelectedListener()
would be the right method to use, but neither get invoked when I select one of the items in the spinner. Is there a correct way to do this? Per commonsware's suggestion, I did the following, but my onItemSelected() method is never being called:

final Spinner spinner = (Spinner) findViewById(R.id.spinner);
spinner.setAdapter( new ArrayAdapter<SettingValue>(getContext(), android.R.layout.simple_list_item_1, android.R.id.text1, setting.getSettingValues() ) );
spinner.setOnItemSelectedListener( new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { Log.d("BOOGA");
final SettingValue settingValue = (SettingValue)parent.getSelectedItem();
final Editor edit = getContext().getSharedPreferences( PREFS_CONTEXT_NAME, Context.MODE_PRIVATE).edit();
edit.putString(setting.name(), settingValue.name());
edit.commit();
} public void onNothingSelected(AdapterView<?> parent) { // do nothing
} } );
