Scrollview внутри переработчика не работает

Question

Я использую программу повторного просмотра с фрагментом.Один из моих фрагментов начинается новый фрагмент, который показывает профиль врача с изображением и длинный текст обо мне.Все работает нормально, кроме вертикальной прокрутки.Это совершенно учебная цель и я нуб на это.Пытаюсь узнать, как это работает.Я приложил фрагмент класса, адаптер и макет.Любой тип справки, предложения, исправления могут спасти меня.Заранее спасибо.

Адаптер

public class DoctorProfileAdapter extends RecyclerView.Adapter<DoctorProfileAdapter.DoctorProfileViewHolder> {

private Context mContext;
private List<Doctors> doctorsList;

public DoctorProfileAdapter(Context mContext, List<Doctors> doctorsList) {
    this.mContext = mContext;
    this.doctorsList = doctorsList;
}

@NonNull
@Override
public DoctorProfileViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.detail_doctor_profile, viewGroup, false);
    return new DoctorProfileViewHolder(view);
}

@Override
public void onBindViewHolder(final DoctorProfileViewHolder holder, final int position) {
    Doctors doctors = doctorsList.get(position);
    holder.name.setText(doctors.getName());
    holder.degree.setText(doctors.getDegree());
    holder.specialty.setText(doctors.getSpecialty());
    holder.departments.setText(doctors.getDepartments());
    holder.bio.setText(doctors.getBio());
    Glide.with(mContext).load(doctors.getThumbnail()).into(holder.thumbnail);
}

@Override
public int getItemCount() {
    return doctorsList.size();
}

public class DoctorProfileViewHolder extends RecyclerView.ViewHolder {
    public TextView name, degree, departments, specialty, bio;
