Android asmak数据包侦听器和自定义IQProvider未触发/调用

我正在一个android项目中使用最新版本（asmack-android-8-source-0.8.3），我试图通过发送多个IQ和接收响应来与服务器通信。 我收到响应并正确解析了它，但包侦听器没有触发它。 我有以下代码：

vCard_IQProvider.java

public class vCard_IQProvider implements IQProvider

    public static final String LAST_ACTIVITY_TS = "LAST_ACTIVITY_TS";
    public static final String FUTURE_STATUS = "FUTURE_STATUS";
    public static final String FUTURE_STATUS_DESCRIPTION = "FUTURE_STATUS_DESCRIPTION";

                    }

                    break;
                }
                case XmlPullParser.END_TAG:
                {
                    done = ELEMENT_NAME.equalsIgnoreCase(name);
                    break;
                }
            }
        }
        name = null;

        return new vCard_IQ(list);
    }
}

和包侦听器：

connection.addPacketListener(new PacketListener()
{
    @Override
    public void processPacket(Packet p)
    {   
        if(p.getPacketID().equals(vCard_IQ.ID))
        {
            vCard_IQ pp = (vCard_IQ)p;

            //access the parsed data
            //vCard_IQ.getData().get.......

            pp = null;
        }
    }
}, 
    new PacketFilter()
    {
        @Override
        public boolean accept(Packet arg0)
        {
            return true;
        }
    }); 

数据包过滤器设置为接受所有数据包，listner由于某种原因未触发。我可以在调试器中看到服务器正在发送响应

我甚至试图通过创建一个asynk任务绕过侦听器，在后台线程中等待，直到解析响应并访问它。现在它只适用于发送的第一个iq-我收到一个响应并正确地解析了它，但对于其余部分，我可以在调试器中看到服务器正在发送响应，但它从未到达解析器。从未调用过的解析器

   Asynk<Void, Void, Void> asynk = new Asynk<Void, Void, Void>()
    {
        Packet iq_vcard;

        @Override

有什么不对的建议吗？

这是aSmack中的一个bug，在无数次尝试修复这个问题后，我自己编译aSmack的尝试失败了，然后尝试了我能想到的任何东西，我做了以下事情：我在android项目中创建了一个新包，并在那里转储了aSmack的所有java类。通过这种方式，我让eclipse编译aSmack，并更好地控制它的代码

问题是，每次我从服务器收到自定义iq响应时，PacketParserUtils.java aSmack都会返回错误的元素名称和命名空间，从而选择错误的iq提供程序来解析响应。

来自文档：

在方法调用结束时，必须将解析器定位在 子元素的结束标记

---

如果有人也这么做，我发现了问题所在

vCard\u IQProvider

类上的条件错误时，应为：

while(!done && parser.next() != XmlPullParser.END_DOCUMENT)

---

否则当done设置为true时，while将再次检查条件并将解析器移动到下一个元素（使用调用

parser.next（）

）。

我不确定我是否正确，但我在应用程序中观察到，当您启动IQ提供程序时，其他数据包侦听器将无法工作。所有类型的传出或传入数据包仅由IQ提供商处理。尝试将所有数据包记录在IQ提供者中，然后您就会知道。

   Asynk<Void, Void, Void> asynk = new Asynk<Void, Void, Void>()
