Android smack

  登陆：

  

if (!ConnectionUtils.getConnection().isConnected())                  return false;if (ConnectionUtils.getConnection().isAuthenticated()) { return true;} else {// 用户登录ConnectionUtils.getConnection().login("username","password"); return ConnectionUtils.getConnection().isAuthenticated();} 

 

 读取消息:

 PacketListener和PacketCollector。

   都使用PacketFilter

 

 PacketFilter packetFilter = new AndFilter(new PacketIDFilter(jp.getPacketID()), new PacketTypeFilter(IQ.class));            // 监听所有的包            con.addPacketListener(new PacketListener() {                public void processPacket(Packet packet) {                    if (packet instanceof MyIQ) {                        MyIQ iq = (MyIQ) packet;                        if (iq.getType() == IQ.Type.RESULT) {                            System.out.println("返回内容："+ iq.toXML());                         }                       }                     else {                        System.out.println("其他消息:"+packet.toXML());                       }                    }            }, packetFilter);         //PacketCollector    PacketFilter filter = new AndFilter(new PacketIDFilter(reg.getPacketID()), new PacketTypeFilter(IQ.class));    PacketCollector collector = ConnectionUtils.getConnection().createPacketCollector(filter);    ConnectionUtils.getConnection().sendPacket(reg);    result = (IQ) collector.nextResult(SmackConfiguration.getPacketReplyTimeout());

  

 添加好友

    在申请添加一个好友，当对方Roster.setDefaultSubscriptionMode(SubscriptionMode.manual)时，此时添加的好友为“挂起”状态。

    对方设置监听

  

PacketFilter filter = new PacketFilter() { @Overridepublic boolean accept(Packet packet) {if (packet instanceof Presence) { Presence presence = (Presence) packet;if (presence.getType().equals(Presence.Type.subscribe)) {return true; } }return false; } };

 允许添加好友则回复消息

 

Presence presence = new Presence(Presence.Type.subscribed); presence.setTo(packet.getFrom()); ConnectionUtils.getConnection().sendPacket(presence);

 此时邀请人的好友状态为to。

 而被添加的user的subscription状态为from。

如果要改为both。

被邀请人应当也发送一个邀请请求。

Presence subscription = new Presence(Presence.Type.subscribe);subscription.setTo(packet.getFrom());ConnectionUtils.getConnection().sendPacket(subscription);

 申请创建联系人 : createEntry(String user, String name, String[] groups)
 删除联系人 : removeEntry(RosterEntry entry)
