Firebase查询未响应子事件侦听器。实际上我正在尝试将手机中的电话号码与Firebase数据库中的电话号码进行比较，并且我已经实施了Firebase查询......这不能按预期工作。这是我的代码

private Firebase userLocationRef = new Firebase("https://XXXX-XXX.fiXXXXXo.cXX/users");

ContentResolver cr = this.getContentResolver(); //Activity/Application android.content.Context
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        if (cursor.moveToFirst()) {
            do {
                String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

                if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                    Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
                    while (pCur.moveToNext()) {
                        final String contactNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        //All Mapping Stuff to be done here..
                        Log.e("Phone Number", contactNumber);


                        com.firebase.client.Query query = userLocationRef.orderByChild("phoneNumber").equalTo(contactNumber);


                        query.addChildEventListener(new ChildEventListener() {
                            @Override
                            public void onChildAdded(DataSnapshot dataSnapshot, String s) {
                                Log.e("Contact Found", "Got Value");
                                dataSource.createContact(contactNumber);
                            }

                            @Override
                            public void onChildChanged(DataSnapshot dataSnapshot, String s) {
                                Log.e("Contact Found", "Got Value again");    
                                dataSource.createContact(contactNumber);
                            }

                            @Override
                            public void onChildRemoved(DataSnapshot dataSnapshot) {
                                Log.e("Contact Found", "Got Value again");
                            }

                            @Override
                            public void onChildMoved(DataSnapshot dataSnapshot, String s) {
                                Log.e("Contact Found", "Got Value again");
                            }

                            @Override
                            public void onCancelled(FirebaseError firebaseError) {
                                Log.e("Contact Found", "Got Value again");
                            }
                        });
                        break;
                    }
                    pCur.close();
                }
            } while (cursor.moveToNext());
        }
    }

和最后但不是最少这里是我在Firebase中的dataBase树

Root
 + friends 
 - users
    - 9xx888xxx
         hasLoggedIn: false
         name:"XXXXXXXXXX"
         phoneNumber:"9xx888xxx"
       + timeStampJoinedaddclose
   + 989xxxx898
   + xxxx000000

我的Firebase查询未响应childEventListener
