Question

我正在使用带有片段的recyclerview。我的一个片段开始了一个新片段，其中显示了医生个人资料，其中包含图像和关于我的文字很长。除了垂直scrollview之外，其他所有东西都可以正常工作。这是完全学习的目的，对此不是新手。尝试学习这些工作原理。我附加了片段类，适配器和布局。任何类型的参考，建议，纠正都可以救我。预先感谢。

适配器

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;
    public ImageView thumbnail;
    public DoctorProfileViewHolder(View view) {
        super(view);
       name = view.findViewById(R.id.name);
       degree = view.findViewById(R.id.degree);
       departments = view.findViewById(R.id.department);
       specialty = view.findViewById(R.id.specialty);
       bio = view.findViewById(R.id.bio);
       thumbnail = view.findViewById(R.id.thumbnail);
    }
}
}

片段

public class DoctorProfileFragment extends Fragment {


private String ID, name, specialty, degree, thumbnail, departments, bio;

private DatabaseReference databaseReference;
private ValueEventListener listener;
private DoctorProfileAdapter adapter;
private List<Doctors> list;
public DoctorProfileFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActivity().setTitle("Profile");
    Bundle bundle = getArguments();
    if (bundle != null) {
        ID = (String) bundle.getSerializable("id");
        name = (String) bundle.getSerializable("name");
        specialty = (String) bundle.getSerializable("specialty");
    }

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    databaseReference = FirebaseDatabase.getInstance().getReference();

    list = new ArrayList<>();
    View view = inflater.inflate(R.layout.blank_fragment, container, false);
    RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
    adapter = new DoctorProfileAdapter(getContext(), list);
    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getContext());
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(adapter);
    asyncTask();
    return view;
}

private void asyncTask(){
    databaseReference = databaseReference.child("doctors").child(ID);
    listener = new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            degree = dataSnapshot.child("degree").getValue(String.class);
            departments = dataSnapshot.child("departments").getValue(String.class);
            bio = dataSnapshot.child("bio").getValue(String.class);
            thumbnail = dataSnapshot.child("thumbnail").getValue(String.class);
            Doctors doctors = new Doctors(name, degree, departments, specialty, thumbnail, bio);
            list.add(doctors);
            adapter.notifyDataSetChanged();
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {

        }
    };
    databaseReference.addValueEventListener(listener);
}

}

RecyclerView中的ScrollView不起作用
