android IM的实现:聊天室(采用smack API)

由于Smack的API版本不一样吧,以为会有个对应的GroupChat来处理聊天室(跟Chat处理普通聊天一样).可我错了,我没有找到这个类

翻了下API,最后发现只有采用MultiUserChat

获取服务器端聊天室信息:

public static void getConferenceRoom() throws XMPPException {if (!MultiUserChat.getHostedRooms(mAdaptee, "127.0.0.1").isEmpty()) {for (HostedRoom k : MultiUserChat.getHostedRooms(mAdaptee,"127.0.0.1")) {for (HostedRoom j : MultiUserChat.getHostedRooms(mAdaptee,k.getJid())) {RoomInfo info2 = MultiUserChat.getRoomInfo(mAdaptee,j.getJid());if (j.getJid().indexOf("@") > 0) {System.out.println("聊天室的名称是： " + j.getName()+ "\n JID是:" + j.getJid());System.out.println("aaNumber of occupants:"+ info2.getOccupantsCount());System.out.println("聊天室的描述：" + info2.getDescription());System.out.println("聊天室的主题:" + info2.getSubject());System.out.println("聊天室的JID:" + info2.getRoom());}}}}}

加入聊天室,获取聊天室的人数,监听消息的发送与接收,监听聊天室的动态:

public static void joinRoom() throws XMPPException{MultiUserChat multiUserChat = new MultiUserChat(mAdaptee, "minzujy@conference.127.0.0.1");multiUserChat.join("NiMei", "");multiUserChat.sendMessage("send message successful");// 发送消息System.out.println(multiUserChat.getOccupantsCount());// 聊天室人数Iterator<String> it = multiUserChat.getOccupants();while(it.hasNext()){// minzujy@conference.127.0.0.1/sushuo1// minzujy@conference.127.0.0.1/guohaiSystem.out.println(StringUtils.parseResource(it.next()));// 聊天室成员名字}multiUserChat.addMessageListener(new PacketListener() {@Overridepublic void processPacket(Packet packet) {Message message = (Message)packet;//接收来自聊天室的聊天信息System.out.println("收到聊天室消息=>" + StringUtils.parseResource(message.getFrom()) + ": "+message.getBody());}});multiUserChat.addParticipantStatusListener(new ParticipantStatusListener() {@Overridepublic void voiceRevoked(String participant) {// TODO Auto-generated method stub}@Overridepublic void voiceGranted(String participant) {// TODO Auto-generated method stub}@Overridepublic void ownershipRevoked(String participant) {// TODO Auto-generated method stub}@Overridepublic void ownershipGranted(String participant) {// TODO Auto-generated method stub}@Overridepublic void nicknameChanged(String participant, String newNickname) {// TODO Auto-generated method stubSystem.out.println(StringUtils.parseResource(participant) + " is now known as "+ newNickname +".");}@Overridepublic void moderatorRevoked(String participant) {// TODO Auto-generated method stub}@Overridepublic void moderatorGranted(String participant) {// TODO Auto-generated method stub}@Overridepublic void membershipRevoked(String participant) {// TODO Auto-generated method stub}@Overridepublic void membershipGranted(String participant) {// TODO Auto-generated method stub}@Overridepublic void left(String participant) {// TODO Auto-generated method stubSystem.out.println(StringUtils.parseResource(participant) + " has left the room.");}@Overridepublic void kicked(String participant, String actor, String reason) {// TODO Auto-generated method stub}@Overridepublic void joined(String participant) {// TODO Auto-generated method stubSystem.out.println(StringUtils.parseResource(participant) + " has joined the room.");}@Overridepublic void banned(String participant, String actor, String reason) {// TODO Auto-generated method stub}@Overridepublic void adminRevoked(String participant) {// TODO Auto-generated method stub}@Overridepublic void adminGranted(String participant) {// TODO Auto-generated method stub}});}

监听好友发送来的加入聊天室的邀请:

MultiUserChat.addInvitationListener(mAdaptee, new InvitationListener() {@Overridepublic void invitationReceived(org.jivesoftware.smack.Connection conn, String room,String inviter, String reason, String password, Message message) {MultiUserChat multiUserChat = new MultiUserChat(conn, room);System.out.println("收到来自 "+inviter+" 的聊天室邀请。邀请附带内容："+reason);try {multiUserChat.join("HMM", password);} catch (XMPPException e) {System.out.println("加入聊天室失败");e.printStackTrace();}System.out.println("成功加入聊天室");multiUserChat.addMessageListener(new PacketListener() {@Overridepublic void processPacket(Packet packet) {Message message = (Message)packet;//接收来自聊天室的聊天信息System.out.println(message.getFrom() + ":" + message.getBody());}});}});
