XMPP——Smack[1]离线消息实现

来源：互联网发布：亳州小鱼网络编辑：程序博客网时间：2024/05/17 07:40

注意事项：

1、登录前要将状态设置为离线：

ConnectionConfiguration connectionConfig = new ConnectionConfiguration(192.168.1.82, 5222, "");connectionConfig.setSendPresence(false);ASmackMainActivity.connection = new XMPPConnection(connectionConfig);

2、接收完离线数据后，要将离线数据清除：

offlineManager.deleteMessages();

3、最后要将用户状态设置为在线。

ConnectionConfiguration connectionConfig = new ConnectionConfiguration(192.168.1.82, 5222, "");connectionConfig.setSendPresence(false);ASmackMainActivity.connection = new XMPPConnection(connectionConfig);connection.login(用户名，密码);OfflineMessageManager offlineManager = new OfflineMessageManager(ASmackMainActivity.connection);        Iterator<org.jivesoftware.smack.packet.Message> it = offlineManager.getMessages();            while(it.hasNext()){                org.jivesoftware.smack.packet.Message message = it.next();                Log.e(TAG, "收到离线消息, Received from 【" + message.getFrom() + "】 message: " + message.getBody());            }            //删除离线消息            offlineManager.deleteMessages();            //将状态设置成在线            Presence presence = new Presence(Presence.Type.available);            ASmackMainActivity.connection.sendPacket(presence);
