无法使用Smack更改我的用户的状态

Question

我试图设置在线模式,但它不能通过名册.我运行此代码并检查我的localhost服务器,该模式仍然"可用"而不是"请勿打扰".

final Connection connection = new XMPPConnection("xxx.xxx.x.xx");

connection.connect();
connection.login("hieugioi@hieund", "123456");

final Roster roster = connection.getRoster();           
Presence p = roster.getPresence("hieugioi@hieund");
p.setPriority(128);
p.setMode(Mode.dnd);

Answer 1

因为您不将Presence数据包发送到服务器.组装完Presence数据包后,您需要发送它.例如:

Presence p = new Presence(available, "I am busy", 42, Mode.dnd);
connection.sendStanza(p);
