Android 如何在xmpp中获得会议成员？

我已经从github下载了yaxim源代码，现在我想获得 会议上，我尝试了下面的代码，但它不起作用

但是roomUsers count返回0

如果有人知道从会议室获取用户列表的其他方法，请告诉我

您需要加入MUC才能查看其成员。

Hi Flow，我在加入会议室后编写了上述代码

String room  = "test@conference.abc";
Connection xmppConnection;
        ConnectionThread connectionThread = AccountManager.getInstance()
                .getAccount(account).getConnectionThread();
        if (connectionThread == null) {
            Application.getInstance().onError(R.string.NOT_CONNECTED);
            return true;
        }
        xmppConnection = connectionThread.getXMPPConnection();
MultiUserChat userChat = new MultiUserChat(xmppConnection, room);
Iterator<String> roomUsers  = userChat.getOccupants();
        System.out.println("roomUsers count === "+userChat.getOccupantsCount());
        while (roomUsers.hasNext()) {
            String roomOccupants = (String) roomUsers.next();
            System.out.println("room users ==== "+roomOccupants);
        }
