How to use typeface (custom fonts) to the selected item in the Spinner

Question

I have made a Custom Multiselect Spinner by extending AppCompatSpinner in my project. When I select an item,it shows the selected items. I don't have clue to use typeface for this selected item that is appeared to the user. please anyone enlighten me. How do I use typeface using style? Is it possible?

  <com.sws.ain.helpers.MultiSelectionSpinner
        android:id="@+id/industries_spinner"
        android:layout_width="200dp"
        style="@style/mySpinnerItemStyle"
        android:layout_height="40dp"
        android:layout_below="@+id/select_country_btn"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="30dp"
        android:paddingBottom="10dp"
        android:background="@drawable/interested_button_shape"
        android:gravity="center"
        android:textAlignment="center" />

Here is the Custom Spinner which works fine.

public class MultiSelectionSpinner extends AppCompatSpinner implements
    OnMultiChoiceClickListener {
String[] _items = null;
boolean[] mSelection = null;
boolean[] mSelectionAtStart = null;
String _itemsAtStart = null;
ArrayAdapter<String> simple_adapter;
private OnMultipleItemsSelectedListener listener;

public MultiSelectionSpinner(Context context) {
    super(context);

    simple_adapter = new ArrayAdapter<>(context,
            R.layout.custom_spinner);

    super.setAdapter(simple_adapter);
}

public MultiSelectionSpinner(Context context, AttributeSet attrs) {
    super(context, attrs);

    simple_adapter = new ArrayAdapter<>(context,
            R.layout.custom_spinner);
    super.setAdapter(simple_adapter);
}

public void setListener(OnMultipleItemsSelectedListener listener) {
    this.listener = listener;
}

public void onClick(DialogInterface dialog, int which, boolean isChecked) {
    if (mSelection != null && which < mSelection.length) {
        mSelection[which] = isChecked;
        //simple_adapter.clear();
        //simple_adapter.add(buildSelectedItemString());
    } else {
        throw new IllegalArgumentException(
                "Argument 'which' is out of bounds.");
    }
}

@Override
public boolean performClick() {
    AlertDialog.Builder builder = new AlertDialog.Builder(getContext(), 
R.style.AlertDialogCustom);
    builder.setTitle("Please select!!!");
    builder.setMultiChoiceItems(_items, mSelection, this);
    _itemsAtStart = getSelectedItemsAsString();
   AlertDialog alertDialog= builder.setPositiveButton("Submit", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            System.arraycopy(mSelection, 0, mSelectionAtStart, 0, mSelection.length);
            listener.selectedIndices(getSelectedIndices(), simple_adapter.getItem(0));
            listener.selectedStrings(getSelectedStrings(), simple_adapter.getItem(0));
        }
    }).create();


    //2. now setup to change color of the button
    alertDialog.setOnShowListener( new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface arg0) {
