java - Android 实时消息传递 Firebase 问题

Question

我想在项目的用户之间添加即时消息。但是我在firebase中遇到了一个问题，android部分的代码是正确的，所以我认为它是正确的，因为在附件中给出的第一个图像中，它进入了数据库引用的子节点并发送了Toast消息。但是firebase部分没有活动。

MainActivity.java

String messageid = databaseReference.child("Mesajlar").child("10").child("13").push().getKey();

    Map messageMap = new HashMap();
    messageMap.put("type","text");
    messageMap.put("time","date");
    messageMap.put("seen","seen");
    messageMap.put("text","messageText");
    messageMap.put("from","10");

    databaseReference.child("Mesajlar").child("10").child("13").child(messageid).setValue(messageMap).addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {

            databaseReference.child("Mesajlar").child("13").child("10").child(messageid).setValue(messageMap).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {

                    Toast.makeText(getApplicationContext(),"Mesajınız İletildi.",Toast.LENGTH_LONG).show();

                }
            });

        }
    });
