java - 无法将简单的 Java Smack 连接到 Google Talk

Question

我想在我的 android 应用程序中发送和接收 gmail 聊天。

我每次都在日志中得到 HostConnection::get() New Host Connection established 0x2a1bfc38, tid 16683。仅此而已。

下面是我的代码。

 XMPPConnection xmpp = new XMPPConnection("gmail.com");
    try {
      xmpp.connect();

      // for other jabber accounts, truncate after the @
      //xmpp.login("username", "password"); 

      // for gtalk / gmail, include the @
      xmpp.login("test04@gmail.com", "***");

      Log.v("nirav", " connect to " + xmpp.getHost());

      ChatManager chatmanager = xmpp.getChatManager();

      Chat newChat = chatmanager.createChat("test04@gmail.com", new MessageListener() {
          // THIS CODE NEVER GETS CALLED FOR SOME REASON
          public void processMessage(Chat chat, Message message) {
            try {
              Log.v(TAG, "Got:" + message.getBody());
              chat.sendMessage(message.getBody());
            } catch (XMPPException e) {
              Log.v(TAG, "Couldn't respond:" + e);
            }
            Log.v(TAG, message.toString());
          }
        });

      try
      {
          newChat.sendMessage("adsd");
      }
      catch(Exception e)
      {
          Log.v(TAG, e.getMessage().toString());
      }

   // Accept only messages from friend@gmail.com
      PacketFilter filter 
          = new AndFilter(new PacketTypeFilter(Message.class), 
                          new FromContainsFilter("test@gmail.com"));

      // Collect these messages
      PacketCollector collector = xmpp.createPacketCollector(filter);

      while(true) {
          Packet packet = collector.nextResult();

          if (packet instanceof Message) {
            Message msg = (Message) packet;
            // Process message
            Log.v(TAG, "Got message:" + msg.getBody());
          }
        }

    }
    catch(Exception e)
    {

    }

这是用于在您的应用程序中发送和接收文本的 gmail 聊天应用程序的解决方案代码。

你应该试试这段代码。希望对您有所帮助。

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    recipient = (EditText) this.findViewById(R.id.toET);
    textMessage = (EditText) this.findViewById(R.id.chatET);
    listview = (ListView) this.findViewById(R.id.listMessages);
    setListAdapter();

    // Set a listener to send a chat text message
    Button send = (Button) this.findViewById(R.id.sendBtn);
    send.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            String to = recipient.getText().toString();
            String text = textMessage.getText().toString();

            Log.i("XMPPChatDemoActivity", "Sending text " + text + " to " + to);
            Message msg = new Message(to, Message.Type.chat);
            msg.setBody(text);              
            if (xmpp != null) {
                xmpp.sendPacket(msg);
                messages.add(xmpp.getUser() + ":");
