Question

我正在使用xmpp和ASMACK android-8-4.0.6开发小型聊天应用程序。在发送消息时，服务器向我发送回复以确认消息已成功到达服务器。回复如下：

<message to="abc@ofsrv1"><a xmlns="urn:xmpp:sm:3" h="6vO1d-7"/></message>

其中属性＆＃39; h＆＃39; inside元素包含已发送消息的包ID。我发送消息如下

public void sendMessage(String to, String messageData)
    {
        try
        {
            Message msg = new Message(to, Message.Type.chat);
            addMessageToLocalDb(to, messageData, msg.getPacketID());
            msg.setBody(messageData);
            DeliveryReceiptManager.addDeliveryReceiptRequest(msg);
            xmppConnection.sendPacket(msg);

        } catch (Exception e)
        {

        }
    }

我附加了数据包监听器，我收到了服务器的回复，但收到的表格如下：

<message to='sender@ofsrv1'><a xmlns='urn:xmpp:sm:3'></a></message>

其中＆＃39; h＆＃39;元素中的属性显然缺失。有趣的部分是我的日志猫，在＆＃34; SMACK＆＃34;标签我收到了完整的回复以及h属性如下

<message to="sender@ofsrv1"><a xmlns="urn:xmpp:sm:3" h="6vO1d-7"/></message>

所以服务器回复成功到达Android客户端但是一些附加的数据包监听器没有收到它。用于附加数据包侦听器的代码是

public void configureConnection()
    {
        try
        {
            //PacketFilter filter1 = new IQTypeFilter(IQ.Type.RESULT);
            PacketFilter filter = new PacketFilter()
            {
                @Override
                public boolean accept(Packet packet)
                {
                    return true;
                }
            };
            XmppPacketListener xmppPacketListener = new XmppPacketListener(this, xmppConnection);
            xmppConnection.addPacketListener(xmppPacketListener, filter);

            //Registering Delivery receipt Listener
            deliveryReceiptManager = DeliveryReceiptManager.getInstanceFor(xmppConnection);
            XmppReceiptReceivedListener receiptReceivedListener = new XmppReceiptReceivedListener();
            deliveryReceiptManager.addReceiptReceivedListener(receiptReceivedListener);

            //Enabling carbons
            CarbonManager carbonManager = CarbonManager.getInstanceFor(xmppConnection);
            if (carbonManager.isSupportedByServer())
            {
                carbonManager.sendCarbonsEnabled(true);
            }

        } catch (Exception e)
        {
            CustomLogger.showLog("Xmpp", "Error in configuring xmpp connection" + e.toString());
        }
    }


public class XmppPacketListener implements PacketListener
{

    private XMPPConnection mXmppConnection;

    private Context mContext;



    public XmppPacketListener(Context context, XMPPConnection xmppConnection)
    {
        CustomLogger.showLog(TAG, "Packet listener init");
        this.mContext = context;
        this.mXmppConnection = xmppConnection;
    }

    @Override
    public void processPacket(Packet packet)

    {

        try
        {
            CustomLogger.showLog("Message", "Received packet" + packet);



        } catch (Exception e)
        {

        }
    }
}

任何人都可以帮我弄清楚接收数据包时到底缺少了什么非常感谢任何帮助
