android - Smack 4.1.0 android 名册不显示

Question

我试图显示所有可用的联系人，即使它没有显示

代码:

Roster roster = Roster.getInstanceFor(connection);
Collection<RosterEntry> entries = roster.getEntries();
System.out.println("ENTRIEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEESS");
int roster_counter = 0;
for (RosterEntry entry : entries) {
     roster_counter++;
     try {
         System.out.println("Here is Roster " + Integer.toString(roster_counter) + ": " + entry);
     }catch (Exception e){
           System.out.println("2222222222222222222222");
           System.out.println(e);
     }
}

输出:

04-01 18:07:41.535    2756-2776/com.example.example I/System.out﹕ ##########################################################
04-01 18:07:41.535    2756-2776/com.example.example I/System.out﹕ ====================================================
04-01 18:07:41.537    2756-2776/com.example.example I/System.out﹕ PRESSSSSEEEEEEN STABLISHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEED

我认为它应该打印所有条目，对吗？但它打印的不是它们。有帮助吗？连接配置是这样的:

configBuilder.setDebuggerEnabled(true);
                configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

如有任何帮助，我将不胜感激。

我修复它添加:

if (!roster.isLoaded()) 
    roster.reloadAndWait();

之后:

Collection<RosterEntry> entries = roster.getEntries();
