存在返回始终可用

Question

我可以从openfire获得所有注册用户，但无法获得所有用户的状态。我已经尝试了以下代码，但无论该用户是在线还是离线，它都会一直返回。请帮助我获取所有用户的状态。任何建议都可以接受。

try
        {
            String username = etUsername.getText().toString();
            String password = etPassword.getText().toString();
            myXMPP.getConnection().login(username, password);

            UserSearchManager usm = new UserSearchManager(myXMPP.getConnection());

            Form searchForm = usm.getSearchForm("search." + myXMPP.getConnection().getServiceName());
            Form answerForm = searchForm.createAnswerForm();
            UserSearch userSearch = new UserSearch();
            answerForm.setAnswer("Username", true);
            answerForm.setAnswer("search", "*");
            ReportedData data = userSearch.sendSearchForm(myXMPP.getConnection(), answerForm, "search." + myXMPP.getConnection().getServiceName());

            if (data.getRows() != null)
            {
                UserInfoDtl contactDetail = new UserInfoDtl(context);

                for(int i=0;i<data.getRows().size();i++)
                {

                    ContentValues values = new ContentValues();
                    String Name = data.getRows().get(i).getValues("Name").toString().replace("[", "").replace("]", "");
                    String Jid = data.getRows().get(i).getValues("jid").toString().replace("[", "").replace("]", "");
                    String Email = data.getRows().get(i).getValues("Email").toString().replace("[", "").replace("]", "");
                    String Status = "";
                    values.put(contactDetail.NAME,Name);

                    //  contactDetail.deleteTable();
                    if(!contactDetail.isUserExist(Jid))
                        contactDetail.insert(values);
                    Roster roster = Roster.getInstanceFor(myXMPP.getConnection());
                    /*Presence availability = roster.getPresence(Jid);
