android - 如何从android获取smack或xmpp中消息的传递状态

Question

这是我的代码，我正在用这种方法发送消息，但无法在 DeliveryReceipt 中获取送达消息

    newChat.sendMessage(message);
            newChat.getListeners();
            newChat.addMessageListener(new ChatMessageListener() {
                @Override
                public void processMessage(Chat chat, Message message) {
                    Log.d(TAG,"DeliveryReceipt3:"+"1:"+message.getThread()+"2:"+chat.getThreadID()+"3:"+message.getBody());
                }
            });

上面的代码用于发送消息，下面的代码用于获取DeliveryReceipt

   Message m = new Message();
                m.setType(Message.Type.chat);
                m.setFrom(connection.getUser());
                m.setTo(agentId);
                m.addExtension(new DeliveryReceipt(m.getPacketID()));

                DeliveryReceipt dr = (DeliveryReceipt)m.getExtension(DeliveryReceipt.ELEMENT, DeliveryReceipt.NAMESPACE);
                Log.d(TAG,"DeliveryReceipt1: "+"1:"+dr.getElementName()+"2:"+dr.getId()+"3:"+dr.getNamespace()+"4:"+dr.toXML()+"4:"+dr.toString());
                Log.d(TAG,"DeliveryReceipt2: "+"1:"+m.getBody()+"2:"+m.getStanzaId()+"3:"+m.getThread());

登录成功后需要添加DeliveryReceiptManager

DeliveryReceiptManager dm = DeliveryReceiptManager.getInstanceFor(connection);
                    dm.setAutoReceiptMode(AutoReceiptMode.always);
                    dm.autoAddDeliveryReceiptRequests();
                    dm.addReceiptReceivedListener(new ReceiptReceivedListener() {

                    @Override
                    public void onReceiptReceived(Jid fromJid, Jid toJid, 
                      final String receiptId, Stanza receipt) {
                             // handle delivery receipt here
                            }
                      });
