Android 的 XMPP/facebook 聊天连接

Question

public class ClientJabberActivity extends Activity {

private final static String SERVER_HOST = "chat.facebook.com";
private final static int SERVER_PORT = 5222;
private final static String SERVICE_NAME = "chat.facebook.com"; 
private final static String LOGIN = "[email protected]";
private final static String PASSWORD = "xxxxxx";


private List<String> m_discussionThread;
private ArrayAdapter<String> m_discussionThreadAdapter;
private XMPPConnection m_connection;
private Handler m_handler;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    m_handler = new Handler();
    try {
        initConnection();
    } catch (XMPPException e) {
        e.printStackTrace();
    }

    final EditText recipient = (EditText) this.findViewById(R.id.recipient);
    final EditText message = (EditText) this.findViewById(R.id.message);        
    ListView list = (ListView) this.findViewById(R.id.thread);

    m_discussionThread = new ArrayList<String>();
    m_discussionThreadAdapter = new ArrayAdapter<String>(this,
            R.layout.multi_line_list_item, m_discussionThread);
    list.setAdapter(m_discussionThreadAdapter);

    Button send = (Button) this.findViewById(R.id.send);
    send.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            String to = recipient.getText().toString();
            String text = message.getText().toString();

            Message msg = new Message(to, Message.Type.chat);
            msg.setBody(text);
            m_connection.sendPacket(msg);
            m_discussionThread.add("moi :");
            m_discussionThread.add(text);
            m_discussionThreadAdapter.notifyDataSetChanged();
        }
    });
}


private void initConnection() throws XMPPException {
    //Initialisation de la connexion
    ConnectionConfiguration config =
            new ConnectionConfiguration(SERVER_HOST, SERVER_PORT, SERVICE_NAME);
    m_connection = new XMPPConnection(config);
    m_connection.connect();
    m_connection.login(LOGIN, PASSWORD);
    Presence presence = new Presence(Presence.Type.available);
    m_connection.sendPacket(presence);

    //enregistrement de l'écouteur de messages
    PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
    m_connection.addPacketListener(new PacketListener() {
            public void processPacket(Packet packet) {
                Message message = (Message) packet;
                if (message.getBody() != null) {
                    String fromName = StringUtils.parseBareAddress(message
                            .getFrom());
                    m_discussionThread.add(fromName + ":");
                    m_discussionThread.add(message.getBody());

                    m_handler.post(new Runnable() {
                        public void run() {
                            m_discussionThreadAdapter.notifyDataSetChanged();
                        }
                    });
                }
            }
        }, filter);
}

}

这段代码我用来与 facebook 聊天建立连接，但无法建立连接，我不知道为什么。它与 Gmail 配合良好

Answer 1

更改：

private final static String LOGIN = "[email protected]";

至：

private final static String LOGIN = "xxxxx";

嗯，不完全是；）。不过你明白了

。facebook 的 XMPP 规范不包括用于登录的@server.here。将其包含在您的用户名字符串中或完全删除您的服务器字符串。

Answer 2
