在带有ScrollView的TextView上实时显示数字

Question

我希望将带有Scroll的ScrollChoise数字立即传输到TextView。set to 3 scroll to 4
set to 4

public class HomeFragment extends Fragment {
TextView textView;

// int [] data=new int[10];
List<String> datas = new ArrayList<>();
ScrollChoice scrollChoice1;




@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_home, container, false);
    scrollChoice1 = v.findViewById(R.id.scroll_choice1);
    textView = v.findViewById(R.id.summTextView);

    loadDatas();
    scrollChoice1.addItems(datas, 2);
    scrollChoice1.setOnItemSelectedListener(new ScrollChoice.OnItemSelectedListener() {
        @Override
        public void onItemSelected(ScrollChoice scrollChoice, int position, String name) {
            textView.setText(name);
        }
    });
    return v;
}

private void loadDatas() {
    datas.add("1");datas.add("2");datas.add("3");datas.add("4");datas.add("5");datas.add("6");datas.add("7");datas.add("8");datas.add("9")
}

当我滚动ScrollView时，会稍有延迟，因此必须从ScrollView中移开手指来更新数字。 如何进行即时切换？
