发送和接收IQ XMPP ASMACK的Android

Question

背景：

我已经在Android的使用asmack库已经能够实现一对一的聊天，通过XMPP。我也能够向服务器发送状态。我为我的基于聊天的应用程序使用OpenFire服务器。

问题： 我使用connection.addPacketListener(new PacketListener()接收消息和智商的分组，对于消息包我已经把它归类这样

PacketFilter Chatfilter = new MessageTypeFilter(Message.Type.chat); 
connection.addPacketListener(new PacketListener() { 
     public void processPacket(Packet packet) { 
      Message message = (Message) packet; 
      if (message.getBody() != null) { 
       String fromName = StringUtils.parseBareAddress(message.getFrom()); 
       Log.i("XMPPClient", "Got text [" + message.getBody() + "] from [" + fromName + "]"); 
       messages.add(fromName + ":"); 
       m1=message.getBody(); 
       messages.add(message.getBody()); 
       // Add the incoming message to the list view 
       /* mHandler.post(new Runnable() { 
       public void run() { 
       setListAdapter(); 
       recieve.setText(m1); 
       } 
       });*/ 
      } 
     } 
}, Chatfilter); 

而且它工作一切正常，但问题出现时我使用类似的东西接收IQ数据包

这里是我用来接收IQ数据包的代码

PacketFilter Iqfilter = new IQTypeFilter(IQ.Type.RESULT); 
connection.addPacketListener(new PacketListener() { 
    public void processPacket(Packet packet) { 
     IQ iq = (IQ) packet; 
     String fromName = StringUtils.parseBareAddress(iq.getFrom()); 
     Log.i("XMPPClient", "Got text [" + iq.toString() + "] from [" + fromName + "]"); 
     m1=iq.getFrom(); 
     mHandler.post(new Runnable() { 
      public void run() { 
       setListAdapter(); 
       recieve.setText(m1); 
      } 
     }); 
    } 
}, Iqfilter); 

我发送一个简单的disco#items查询，它不会响应，即使它不进入功能，我试图调试它，以及，我也试图发送简单PING命令，但它不回应它也是。 我在这里错过了什么？

其次我在将IQ数据包发送到服务器或其他客户端时也遇到了问题。我在某处读到我应该这样做。但它不起作用。

final IQ iq = new IQ() { 
      public String getChildElementXML() { 
      return "<query xmlns='http://jabber.org/protocol/disco#info'/>"; // here is your query 
      //this returns "<iq type='get' from='User@YourServer/Resource' id='info1'> <query xmlns='http://jabber.org/protocol/disco#info'/></iq>"; 
      }}; 
      // set the type 
      iq.setType(IQ.Type.GET); 

      // send the request 
      connection.sendPacket(iq); 

混乱的事情是，当我读到XMPP的针对Android有人写了送你需要有接收器的地址以及智商的文档和asmack。但在这个代码中我们没有设置任何接收器。

对于XMPP asmack和Android，互联网上的信息要少得多。

我认为问题在于您的提供者没有注册。请看this。在Android上，您必须在形成XMPP连接之前手动注册提供者。下面的类复制到项目

    } 
} 

调用此方法像这样

ServiceProviders.Register_Providers(ProviderManager.getInstance()); 

所以尽量停靠在你的应用程序的开始或形成连接之前调用此方法。

希望这有助于
