我在android系统是新来的XMPP / asmack。
任何人都可以请帮我在得到用户的朋友的存在（名单列表）
我使用这样的：
Presence availability = roster.getPresence(user);
Mode userMode = availability.getMode();
还有什么我应该做的就是在我的名单中列出的每个用户的可用性状态。
Answer 1:
只要使用这样的：
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;
}
让我知道如果你有任何关于XMPP / asmack任何问题
Answer 2:
使用这样
userFromServer = con.getRoster().getPresence(userID);
userState = retrieveState(userFromServer.getMode(), userFromServer.isAvailable());
public int retrieveState(Mode userMode, boolean isOnline) {
int userState = XmppFriend.OFFLINE; // default return value
if (userMode == Mode.dnd) {
userState = XmppFriend.BUSY;
} else if (userMode == Mode.away || userMode == Mode.xa) {
userState = XmppFriend.AWAY;
} else if (isOnline) {
userState = XmppFriend.ONLINE;
}
return userState;
}
Answer 3:
roster.addRosterListener(new RosterListener() {
public void entriesAdded(Collection<String> param) {}
public void entriesDeleted(Collection<String> addresses) {
}
public void entriesUpdated(Collection<String> addresses) {
}
public void presenceChanged(Presence presence) {
String user = presence.getFrom();
Presence bestPresence = roster.getPresence(user);
Log.d(TAG, "BestPresence: " + user + ": " + bestPresence);
String[] temp = presence.getFrom().split("\\@");
Log.d(TAG, "Presence: " + temp[0] + "-" + presence.toString());
String status = presence.toString();
// ShowInfoDialog(temp[0]+"is "+status);
for (int i = 0; i < friendslist.size(); i++) {
if (temp[0].equalsIgnoreCase(friendslist.get(i).getName())) {
friendslist.get(i).setStatus(status);
Log.d(TAG, "kilepet/belepet " + friendslist.get(i).getName() + " - " + friendslist.get(i).getStatus());
// ShowInfoDialog(friendslist.get(i).getName()+"is "+status);
Log.d(TAG, "WATERFAK");
}
}
}
如果你使用RosterListener，它实时更新的存在，它为我工作就好了。

并呼吁里面你的方法。
Answer 5:
由于我的经验，才能从在场看到状态和其他需要订阅用户。
例如：用户A希望看到来自用户B状态和可用状态，在这种情况下，用户需要订阅用户B.用户A后，可以看到用户B的存在。
订阅代码
try {
roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);
String userName = responders.getUsers().get(i).getUsername();
roster.createEntry("userB@domain", userName, null);
Presence pres = new Presence(Presence.Type.subscribe);
pres.setFrom("userA@domain");
connection.sendStanza(pres);
} catch (Exception e) {
android.util.Log.e("tag", "unable to add contact: ", e);
}
