Java – how to use fragment’s Spinner event in the main class?

The following code named presenter is my main course. I will replace fragment according to the problem

public class Presenteter extends AppCompatActivity   {
    private final Questions question1Fragment = new Questions();
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.present);

FragmentTransaction ft=getSupportFragmentManager().beginTransaction();
        ft.setCustomAnimations(android.R.anim.fade_in,android.R.anim.fade_out);

         ft.replace(R.id.flPersonalization, question1Fragment);

        ft.commit();
}

This is my problem class. It is getting problems from the rest server. All the problems are listed in a spinner. I didn't write them here to avoid confusing you

public class Questions extends Fragment implements AdapterView.OnItemSelectedListener {
    SearchableSpinner spinner;

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.question, container, false);
  LinearLayout ln=(LinearLayout)view.findViewById(R.id.listLayout);
          spinner=(SearchableSpinner)view.findViewById(R.id.spinner1);
}

Finally, I want to use Spinner's onitemselected () event in the presenter class

How can I do this? Thank you in advance

resolvent:

You can do the following in a clip:

Presenteter p = (Presenteter) getActivity();

// ...

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        p.yourMethod(); // call a method of your Presenteter class
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});
