多用户聊天中的smack状态侦听器

对于多用户聊天,您不必使用花名册,因为遇到花名册中没有的人是正常的。

要知道谁在厕所里,首先要问一下住户:

muc.join(user,password);

List<String> occupantsAtJoinTime = muc.getOccupants();

                    for (String occupant : occupantsAtJoinTime)
                    {
                        System.out.println("occupant: "+occupant);
                        //actions
                    }

然后,要更新占用者列表,请向muc注册DefaultParticipantStatusListener并定义该Listener:

muc.addParticipantStatusListener(new CustomParticipantStatusListner());

定义为(如果需要,可以实现许多方法):

    public class CustomParticipantStatusListner extends DefaultParticipantStatusListener 
    {

        public void joined(String participant) 
        {
            System.out.println(participant + "just joined MUC");
//actions (add occupantsRightNow)
        }

        public void left(String participant)
        {
            System.out.println(participant + " just left MUC");
//actions (remove occupantsRightNow)
        }
    }

所有这一切都很糟糕4.1.7

这是关于多用户聊天中的管理角色修改。 此示例显示如何向访问者授予语音并侦听通知事件:

// User1 creates a room
  muc = new MultiUserChat(conn1, "myroom@conference.jabber.org");
  muc.create("testbot");

  // User1 (which is the room owner) configures the room as a moderated room
  Form form = muc.getConfigurationForm();
  Form answerForm = form.createAnswerForm();
  answerForm.setAnswer("muc#roomconfig_moderatedroom", "1");
  muc.sendConfigurationForm(answerForm);

  // User2 joins the new room (as a visitor)
  MultiUserChat muc2 = new MultiUserChat(conn2, "myroom@conference.jabber.org");
  muc2.join("testbot2");
  // User2 will listen for his own "voice" notification events
  muc2.addUserStatusListener(new DefaultUserStatusListener() {
      public void voiceGranted() {
          super.voiceGranted();
          ...
      }
      public void voiceRevoked() {
          super.voiceRevoked();
          ...
      }
  });

  // User3 joins the new room (as a visitor)
  MultiUserChat muc3 = new MultiUserChat(conn3, "myroom@conference.jabber.org");
  muc3.join("testbot3");
  // User3 will lister for other occupants "voice" notification events
  muc3.addParticipantStatusListener(new DefaultParticipantStatusListener() {
      public void voiceGranted(String participant) {
          super.voiceGranted(participant);
          ...
      }

      public void voiceRevoked(String participant) {
          super.voiceRevoked(participant);
          ...
      }
  });

  // The room's owner grants voice to user2
  muc.grantVoice("testbot2");

首先,加入聊天室:

public MultiUserChat joinMultiUserChat(String user, String roomsName,
        String password) {
    if (getConnection() == null)
        return null;
    try {
        MultiUserChat muc = new MultiUserChat(getConnection(), roomsName
                + "@conference." + getConnection().getServiceName());
        DiscussionHistory history = new DiscussionHistory();
        history.setMaxChars(0);
        // history.setSince(new Date());
        muc.join(user, password, history,
                SmackConfiguration.getPacketReplyTimeout());
        Log.i("MultiUserChat", "Chat room【"+roomsName+"】joined........");
        return muc;
    } catch (XMPPException e) {
        e.printStackTrace();
        Log.i("MultiUserChat", "Chat room【"+roomsName+"】failed........");
        return null;
    }
}

然后,使用MultiChatUser发送消息:

try {
    multiUserChat.sendMessage(message);
} catch (XMPPException e) {
    e.printStackTrace();
}

添加侦听器:

import org.jivesoftware.smack.PacketListener;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.packet.Packet;

public class TaxiMultiListener implements PacketListener {
    @Override
    public void processPacket(Packet packet) {
        Message message = (Message) packet;
        String body = message.getBody();
    }
}

最后,使用MultiUserChat呼叫侦听器:

multiUserChat.addMessageListener(new TaxiMultiListener());
