Here is a better implementation -

Custom Spinner Class -

import android.content.Context;
import android.util.AttributeSet;
import androidx.appcompat.widget.AppCompatSpinner;

public class CSpinner extends AppCompatSpinner {

    private int lastPosition = 0;

    public CSpinner(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setSelection(int position) {
        super.setSelection(position);
        boolean sameSelected = lastPosition == getSelectedItemPosition();
        OnItemSelectedListener onItemSelectedListener = getOnItemSelectedListener();
        if (sameSelected && onItemSelectedListener != null) {
            onItemSelectedListener.onItemSelected(this, getSelectedView(), position, getSelectedItemId());
        }
        lastPosition = position;
    }
}

Setting Listener -

spn.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView parent, View view, int position, long id) {
            Log.d("onItemSelected", String.valueOf(position));
        }

        @Override
        public void onNothingSelected(AdapterView parent) {
            
        }
    });
