Android Spinner with different layouts for “drop down state” and “closed state”?

Question

I have an Android Spinner view in my layout. I would like that spinner to show only a single text item when closed, but when the user clicks on it (i.e. opens the spinner di

Using the code of the tutorial linked by Flo, I created the following CustomSpinnerAdapter in order to show two different sets of strings, one when the items are displayed, and one when not. I hope it helps someone.

public class CustomSpinnerAdapter extends ArrayAdapter {

Context mContext;
int mTextViewResourceId;
String[] mObjects;
String[] mShortNameObjects;

public CustomSpinnerAdapter(Context context, int textViewResourceId,
                            String[] objects, String[] shortNameObjects) {
    super(context, textViewResourceId, objects);
    mContext = context;
    mTextViewResourceId = textViewResourceId;
    mObjects = objects;
    mShortNameObjects = shortNameObjects;
}

@Override
public View getDropDownView(int position, View convertView,
                            ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    TextView row = (TextView) inflater.inflate(mTextViewResourceId, parent, false);
    row.setText(mObjects[position]);

    return row;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    return getCustomView(position, convertView, parent);
}

public View getCustomView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    TextView row = (TextView) inflater.inflate(mTextViewResourceId, parent, false);
    row.setText(mShortNameObjects[position]);

    return row;
}
}

And the usage inside a Fragment:

CustomSpinnerAdapter mSpinnerAdapter = new CustomSpinnerAdapter(getActivity(), R.layout.spinner_item, getResources().getStringArray(R.array.action_filter), getResources().getStringArray(R.array.action_filter_short_names));

Finally, the layout for the spinner item:

spinner_item.xml
