Android 如何接受MUC的邀请？

我正在用xmpp开发聊天应用程序。我已经使用MUC创建了组，并向其他用户发送了邀请。但我不知道如何接受和拒绝邀请

以下是我发送邀请的代码：

 EntityBareJid userInviteJID = JidCreate.entityBareFrom("user2@servicename");
 muc2.invite(userInviteJID, "Meet me in this excellent room");

我尝试了

多用户聊天。拒绝（conn，room，inviter.asBareJid（）s，“我现在很忙”）invitationReceived（）方法中的方法。但问题是MultiUserChat.Decept（）方法给出了错误：

无法解析方法拒绝（）

有人能帮我吗？
我找到了拒绝邀请的答案

此函数被移动到MultiUserChatManager，它与MultiUserChat的特定实例没有关系，因此它是静态的，现在是管理器的一个函数

MultiUserChatManager.getInstanceFor(connection).decline(roomJID,inviter.asEntityBareJid(),"reason");

但如何接受邀请呢？任何人都可以回答我，请？
您需要在收到邀请时自动加入，以下是连接完成时的代码

 MultiUserChatManager.getInstanceFor(MyApplication.connection).addInvitationListener(new InvitationListener() {
        @Override
        public void invitationReceived(XMPPConnection conn, MultiUserChat room, EntityJid inviter, String reason, String password, Message message, MUCUser.Invite invitation) {
            //  Log.e(TAG, "invitationReceived() called with: conn = [" + conn + "], room = [" + room + "], inviter = [" + inviter + "], reason = [" + reason + "], password = [" + password + "], message = [" + message + "], invitation = [" + invitation + "]");
            LogM.e("invitationReceived() called with: conn = [" + conn + "], room = [" + room + "], inviter = [" + inviter + "], reason = [" + reason + "], password = [" + password + "], message = [" + message + "], invitation = [" + invitation + "]");

            try {
                Resourcepart nickname = null;
                try {
                    nickname = Resourcepart.from("MY_JID_HERE");
                } catch (XmppStringprepException e) {
                    e.printStackTrace();
                }

                try {

                    room.join(nickname); //while get invitation you need to join that room
                    room.getRoom().getLocalpart();
                } catch (SmackException.NoResponseException e) {
                    e.printStackTrace();
                } catch (SmackException.NotConnectedException e) {
                    e.printStackTrace();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } catch (MultiUserChatException.NotAMucServiceException e) {
                    e.printStackTrace();
                }

                Log.e(TAG, "join room successfully");

            } catch (XMPPException e) {
                e.printStackTrace();
                Log.e(TAG, "join room failed!");
            }

        }
    });
