How to include spinner to alert dialog or display it as alert dialog or some alternative

Question

I created my spinner dropdown and it's working perfectly but my client suddently decided that he want an alert dialog instead of dropdown list. Is there any easy way to achieve that. I never worked with alert dialogs and this is new for me. Would appreciate any advice? What do I need to change inflate etc so when user click on spinner it open an alert dialog with list in it so user can select year and month and send network request.

public class Izvjestaji extends Fragment {
// The onCreateView method is called when Fragment should create its View object hierarchy,
// either dynamically or via XML layout inflation.

private int godinaPozicija = 0;
private int mjesecPozicija = 0;
private Spinner godina;
private Spinner mjesec;
private int offset = 0;
private ArrayList<Transactions> listTransactons;
private SwipyRefreshLayout swipyRefreshLayout;
private boolean isFirstLoad=true;

ListView list;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
    // Defines the xml file for the fragment
    View rootView = inflater.inflate(R.layout.izvjestaji, parent, false);
    int year = Calendar.getInstance().get(Calendar.YEAR);
    int month = Calendar.getInstance().get(Calendar.MONTH);
    swipyRefreshLayout = (SwipyRefreshLayout) rootView.findViewById(R.id.swipyrefreshlayout);
    listTransactons = new ArrayList<>();
    List<Integer> list = new ArrayList<Integer>();
    for (int i = 2015; i <= year; i++) {
        list.add(i);

    }
    List<String> list2 = new ArrayList<String>();
    list2.add("Januar");
    list2.add("Februar");

    list2.add("Juli");

    list2.add("Septembar");
    list2.add("Oktobar");

Have you tried,

<Spinner style="@android:style/Widget.Spinner.DropDown" ... />

or

<Spinner android:spinnerMode="dropdown" ... />
