android - 使用 FirebaseRecyclerAdapter 的 Firebase 搜索实现

Question

我对 FirebaseRecyclerAdapter 的想法非常陌生，因此有一个非常基本的问题要问。我正在使用此代码制作一个应用程序，用户可以在其中输入他们的专业/服务。然后我希望在他们使用他们的职业名称进行搜索时显示他们的个人资料。这是我正在使用的代码：

private TextInputLayout searchServicees;
private Button searchBtn;
private RecyclerView serviceesList;
private DatabaseReference databaseReference;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search);

    searchServicees=findViewById(R.id.searchServicees);
    searchBtn=findViewById(R.id.searchBtn);
    serviceesList=findViewById(R.id.serviceesList);
    serviceesList.setHasFixedSize(true);
    serviceesList.setLayoutManager(new LinearLayoutManager(this));

    databaseReference=FirebaseDatabase.getInstance().getReference("User");

    searchBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String searchTxt=searchServicees.getEditText().getText().toString();
            firebaseSearch(searchTxt);
        }
    });
}

private void firebaseSearch(String search)
{
    Query firebaseQuery=databaseReference.orderByChild("service_Offered").startAt(search).endAt(search+"\uf8ff");
    FirebaseRecyclerAdapter<UserSearch,UsersViewHolder> firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<UserSearch, UsersViewHolder>(
            UserSearch.class,R.layout.list_layout,UsersViewHolder.class,firebaseQuery)
    {
        @Override
        protected void onBindViewHolder(@NonNull UsersViewHolder holder, int position, @NonNull UserSearch model) {
            holder.setDetails(model.getCost_inDollars(),model.getDescription_Of_Service(),model.getName(),model.getService_Offered());
        }

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

public static class UsersViewHolder extends RecyclerView.ViewHolder
{
    View mView;
    public UsersViewHolder(@NonNull View itemView)
    {
        super(itemView);
        mView=itemView;
    }
    public void setDetails(String userCost,String userDes,String userName,String userService)
    {
        TextView name=mView.findViewById(R.id.searchName);
        TextView service=mView.findViewById(R.id.searchService);
        TextView des=mView.findViewById(R.id.searchDes);
        TextView cost=mView.findViewById(R.id.searchCost);

        name.setText(userName);
        service.setText(userService);
        des.setText(userDes);
        cost.setText(userCost);
    }
}

现在在 FirebaseRecyclerAdapter firebaseRecyclerAdapter=new FirebaseRecyclerAdapter(UserSearch.class,R.layout.list_layout,UsersViewHolder.class,firebaseQuery) 部分显示以下错误：

FirebaseRecyclerAdapter 中的 FirebaseRecyclerAdapter() 不能应用于：

预期参数：选项：com...com.example.servicees.UserSearch>

实际参数：

com...com.example.servicees.UserSearch> UserSearch.class (java...com.example.servicees.UserSearch>)

R.layout.list_layout (int)

UsersViewHolder.class (java...SearchActivity.UsersViewHolder>)

firebaseQuery (com.google.firebase.database.Query)

谁能告诉我我在哪里做错了？
