如何在Smack中正确收听MultiUserChat？ [英] How to properly listen for MultiUserChat in Smack?

问题描述

我不确定如何正确地监听MultiUserChats，因为显然有两种不同的监听方法。

I'm not sure how to properly listen for MultiUserChats, since there are apparently two different ways to listen for them.

第一种方法是添加MessageListener对于每个房间，像这样：

The first way is to add a MessageListener for each room, like this:

MultiUserChat muc = new MultiUserChat(connection,"MyGroup");
muc.addMessageListener(new PacketListener() {
    @Override
    public void processPacket(Packet packet) throws NotConnectedException {
        // TODO Auto-generated method stub
    }
});

第二种方法是像平常的单聊消息一样收听：

The second way is to listen as you would for normal single-chat messages:

PacketFilter filter = new MessageTypeFilter(Message.Type.groupchat);
connection.addPacketListener(new PacketListener() {
    @Override
    public void processPacket(Packet packet) {
        Message message = (Message) packet;
        if (message.getBody() != null) {
            final String fromName = StringUtils.parseBareAddress(message.getFrom());
            final String Rtext = message.getBody();

考虑到我也在听文件传输，请您帮我弄清楚哪种方法是正确的方法？

Considering that I am also listening for file transfers, could you please help me figure out which way is the proper way?

推荐答案

由于原始代码都有错误，因此我使用了以下代码：

Since the Original Codes both Had Bugs, i used This code:

     PacketFilter messageFilter =

                new AndFilter(

                    new FromMatchesFilter(roomName+"@conference.reza-hp",true),

                    new MessageTypeFilter(Message.Type.groupchat));

            messageFilter = new AndFilter(messageFilter, new PacketFilter() {

                public boolean accept(Packet packet) {

                    Message msg = (Message) packet;

                    return msg.getBody() != null;



                }

            });

          addMessageListener(messageFilter);  
 }

    public static void addMessageListener(PacketFilter messageFilter) {

            connection.addPacketListener(new PacketListener() {

                @Override
                public void processPacket(Packet packet) throws NotConnectedException {
                     Message message = (Message)packet;  
                    String roomName = (message.getFrom().split("\\@conference.reza-
 hp"))[0];
                    String fromUser =    
 (StringUtils.parseResource(message.getFrom()).split("@\\@reza-hp"))[0];

                     System.out.println("=>"+"Room : "+roomName + "From   
 user:"+fromUser + ": "+message.getBody());  

                }
            }, messageFilter);



        }
