如何从特定文档中获取值并将其放入RecyclerView

Question

我只想在recyclerview中显示特定文档中的字段。除了在FirestoreRecyclerOptions内部传递查询以返回集合中的所有文档外，我在Internet上找不到任何解决方案。

如何在recyclerview中仅显示一个文档字段，而不是全部？ 例如：显示第一个文档的电子邮件，名称，电话号码。

我用来显示集合用户中所有文档的代码：

private CollectionReference colref = fStore.collection("users");
PassengerAdapter mDriverAdapter;

private void setUpRecyclerView() {
        Query query = colref;
        FirestoreRecyclerOptions<PassengerDetails> options = new FirestoreRecyclerOptions.Builder<PassengerDetails>()
                .setQuery(query, PassengerDetails.class)
                .build();
        mDriverAdapter = new PassengerAdapter(options);
        RecyclerView recyclerView = findViewById(R.id.recylerview);
        recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(mDriverAdapter);

    }

PassengerAdapter类：

class PassengerAdapter extends FirestoreRecyclerAdapter<PassengerDetails, PassengerAdapter.PassengerHolder> {

    public PassengerAdapter(@NonNull FirestoreRecyclerOptions<PassengerDetails> options) {
        super(options);
    }
    @Override
    protected void onBindViewHolder(@NonNull PassengerAdapter.PassengerHolder holder, int position, @NonNull PassengerDetails model) {
        holder.name.setText(model.getName());
        holder.phone.setText(model.getPhoneno());

    }
    @NonNull
    @Override
    public PassengerAdapter.PassengerHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.passenger_list,
                parent, false);
        return new PassengerAdapter.PassengerHolder(v);
    }
    class PassengerHolder extends RecyclerView.ViewHolder {
        TextView name;
        TextView phone;

        public PassengerHolder(View itemView) {
            super(itemView);
            name = itemView.findViewById(R.id.name);
            phone = itemView.findViewById(R.id.phoneno);
        }
    }
}

PassengerDetails

public class PassengerDetails {
    String fName,phoneno;

    public PassengerDetails(){

    }


    public PassengerDetails(String name, String phoneno) {
        this.fName = name;
        this.phoneno = phoneno;
    }

    public String getName() {
        return fName;
    }

    public void setName(String name) {
        this.fName = name;
    }

    public String getPhoneno() {
        return phoneno;
    }

    public void setPhoneno(String phoneno) {
        this.phoneno = phoneno;
    }
}
