从Firebase检索而没有父键

Question

我正在尝试从Firebase检索一些数据， 并且我只想在“组织”等于组织中当前登录名的情况下检索服务“ NOT Services”，但是当我尝试运行此代码时，它不会检索任何东西

这是我的数据库：

这是我的代码：

    reservation=new Reservation();


    ListView = (android.widget.ListView) findViewById(R.id.ListView);
    database = FirebaseDatabase.getInstance();
    mAuth = FirebaseAuth.getInstance();
    user =  mAuth.getCurrentUser();
    userId = user.getUid();

    name=database.getReference().child("client").child(userId).child("name").toString();
    //ref =  database.getReference().child("reservaiton");
    DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
    DatabaseReference itemsRef = rootRef.child("reservaiton");
    Query query=itemsRef.orderByChild("org").equalTo(name);
    list = new ArrayList<>();
    list1 = new ArrayList<>();
    adapter = new ArrayAdapter<String>(this, R.layout.requesttext,R.id.requestInfo,list);

    query.addValueEventListener(new ValueEventListener() {


        public void onDataChange(DataSnapshot dataSnapshot) {


            for (DataSnapshot ds : dataSnapshot.getChildren()) {
                String str;
                reservation = ds.getValue(Reservation.class);
                        str = reservation.getService().toString() + " \n\n ";
                        list.add(str);
                        list1.add(reservation);


            }

            ListView.setAdapter(adapter);
            ListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                    Intent intent = new Intent(ApproveResrvation.this, orginforequest.class);
                    intent.putExtra("reservation", (Serializable) list1.get(position));
                    startActivity(intent);



                }
            });
        }

        @Override
        public void onCancelled(DatabaseError databaseError){


        }
    });

这是我的预订课程：

package com.example.atheer.booklyv1;

public class Reservation {

    private String approved;
    private String date;
    private String service;
    private String org, orgID, resNum;
    private String time,Uid;
    private int num;


    public String getUid() {
        return Uid;
    }

    public void setUid(String uid) {
        Uid = uid;
    }

    public String getOrgID() {
        return orgID;
    }

    public void setOrgID(String orgID) {
        this.orgID = orgID;
    }

    public String getResNum() {
        return resNum;
    }

    public void setResNum(String resNum) {
        this.resNum = resNum;
    }

    public Reservation(String approved, String date, String service, String org, String orgID, String resNum, String time, String uid, int num) {

        this.approved = approved;
        this.date = date;
        this.service = service;
        this.org = org;
        this.orgID = orgID;
        this.resNum = resNum;
        this.time = time;
        Uid = uid;
        this.num = num;
    }

    public Reservation(){

    }

    public Reservation(String approved, String date, String service, String org, String time, int num) {
        this.approved = approved;
        this.date = date;
        this.service = service;
        this.org = org;
        this.time = time;
        this.num = num;
    }

    public String getApproved() {
        return approved;
    }

    public void setApproved(String approved) {
        this.approved = approved;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getService() {
        return service;
    }

    public void setService(String service) {
        this.service = service;
    }

    public String getOrg() {
        return org;
    }

    public void setOrg(String org) {
        this.org = org;
    }

    public String getTime() {
        return time;
    }

    public void setTime(String time) {
        this.time = time;
    }

    public int getNum() {
        return num;
    }

    public void setNum(int num) {
        this.num = num;
    }
}
