我正在尝试获取Firebase的一些数据 . 我想做orderby（） . equalTo（）但我总是在查询中得到null . 我尝试过两个值deliverBy（boolean）和deliverBy（long） .
Query
queryFirebase = FirebaseDatabase.getInstance().getReference().child("rooms").orderByChild("read").equalTo(false);
queryFirebase.addListenerForSingleValueEvent(new ValueEventListener() {
Send my message to Firebase
Long userId = ApplicationConfig.getCurrentUser().getId();
String toServerUnicodeEncoded = StringEscapeUtils.escapeJava(etMessage.getText().toString());
MessageFirebase message = new MessageFirebase(toServerUnicodeEncoded, new DateTime().toString("yyyy-MM-dd'T'HH:mm:ss'Z'"), userId);
DatabaseReference messageRef = mFirebaseDatabaseReference.push();
messageRef.setValue(message);
MY JSON
{
"rooms" : {
"-KtMBWKEf7-Ot8HdMtbd" : {
"-KtMC7CglZZ-Yp4_PQOU" : {
"blocked" : false,
