如何在Viewpager片段中使整个屏幕可滚动

public class MyFragment extends Fragment {
    private ScrollView scrollView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        scrollView = view.findViewById(R.id.scroll_view);
        return view;
    }

    @Override
    public void setUserVisibleHint(boolean isVisibleToUser) {
        super.setUserVisibleHint(isVisibleToUser);
        if (scrollView != null) {
            scrollView.setScrollable(isVisibleToUser);
        }
    }
}
