  Roster roster = Roster.getInstanceFor(connection);    
//Get all rosters

        } catch (SmackException.NotLoggedInException |        SmackException.NotConnectedException | InterruptedException e) {
            e.printStackTrace();
        }
    Collection<RosterEntry> entries = roster.getEntries();
//loop through
    for (RosterEntry entry : entries) {
//example: get presence, type, mode, status
        Presence entryPresence = roster.getPresence(entry.getUser());
        StatusMode statusMode= StatusMode.createStatusMode(entryPresence);
//            statusMode.getMode();
        Presence.Type userType = entryPresence.getType();
        Presence.Mode mode = entryPresence.getMode();
        String status = entryPresence.getStatus();

        }

        @Override
        public void entriesAdded(Collection<String> addresses) {
        }

        public void entriesUpdated(Collection<String> addresses) {
        }

        public void presenceChanged(Presence presence) {

        }
    });

推荐答案

有关文档，请参阅此处关于 Xmpp 和此处了解详情

for document refer here about Xmpp and here for details

这里是查找用户状态的代码

Here the code for finding user state

 Presence availability = roster.getPresence(user);
 Mode userMode = availability.getMode();

 retrieveState_mode(availability.getMode(),availability.isAvailable());

 public static int retrieveState_mode(Mode userMode, boolean isOnline) {
    int userState = 0;
    /** 0 for offline, 1 for online, 2 for away,3 for busy*/
    if(userMode == Mode.dnd) {
        userState = 3;
    } else if (userMode == Mode.away || userMode == Mode.xa) {   
        userState = 2;
    } else if (isOnline) {
        userState = 1;
    }
    return userState;
}
