android基于Xmpp的即时通讯开发

项目要求实现，基于Xmpp的即时通讯，原因嘛，大家都懂的。

用的smack4.17的jar

public class XmppTool {
    private static XMPPTCPConnectionConfiguration connConfig;
    private static AbstractXMPPConnection con;
    private static TaxiConnectionListener taxiConnectionListener;//重连监听
    private static OfflineMessageManager offlineManager;//离线消息管理

    // 静态加载ReconnectionManager ,重连后正常工作
    static {
        try {
            Class.forName("org.jivesoftware.smack.ReconnectionManager");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static OfflineMessageManager getOffLineMessageManager() {
        if (offlineManager == null) {
            offlineManager = new OfflineMessageManager(con);
        }
        return offlineManager;
    }

    private static void openConnection() {
        try {
            XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
            builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
            connConfig = builder.setServiceName(Constant.OPENFIRE_SERVICENAME).setHost(Constant.OPENFIRE_HOST).setPort(Constant.OPENFIRE_PORT).setCompressionEnabled(false).setSendPresence(false)
                    .build();
            ProviderManager providerManager = new ProviderManager();
            con = new XMPPTCPConnection(connConfig);
            con.connect();
            offlineManager = new OfflineMessageManager(con);
            configure(providerManager);
         /*   final PingManager pingManager = PingManager.getInstanceFor(getConnection());
            pingManager.setPingInterval(5);
            pingManager.registerPingFailedListener(new PingFailedListener() {

                @Override
                public void pingFailed() {
                    pingManager.setPingInterval(2);
                }
            });*/

        } catch (Exception e) {
            e.printStackTrace();
            // TODO: handle exception
        }
    }

    public static TaxiConnectionListener getTaxiConnectionListener() {
        return taxiConnectionListener;
    }

    public static void setTaxiConnectionListener(TaxiConnectionListener taxiConnectionListener) {
        XmppTool.taxiConnectionListener = taxiConnectionListener;
        getConnection().addConnectionListener(XmppTool.taxiConnectionListener);
    }

    public static AbstractXMPPConnection getConnection() {
        if (con == null || !con.isConnected()) {
            openConnection();
        }
        return con;
    }

    public static void closeConnection() {

        if (con != null) {
            con.removeConnectionListener(XmppTool.taxiConnectionListener);
        }
        con.disconnect();

    }

    }

该类主要是用户客户端与服务器建立连接。

public static boolean login(String account, String password, Context context) {
    try {
        if (XmppTool.getConnection() == null)
            return false;
        /** 登录 */

        //SASLAuthentication.supportSASLMechanism("PLAIN");
        XmppTool.getConnection().login(account, password);
        // 设置登录状态：在线
        Presence presence = new Presence(Presence.Type.unavailable);
        XmppTool.getConnection().sendStanza(presence);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return false;
}

登录设置为离线状态这是为了获取离线消息，调用登录方法之后接着调用获取离线消息的方法，获取消息的入口放在服务中。

public static List getOffLine(Context context) {
    Log.i("connectMethod", "getOffLine()");
    List msglist = new ArrayList();
    // 获取离线消息,线程阻塞 不能Toast
    try {
        msglist = XmppTool
                .getOffLineMessageManager().getMessages();
        for (int i = 0; i < msglist.size(); i++) {
            sendBroadcastMsg(context, msglist.get(i));
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            // 设置在线
            XmppTool.getOffLineMessageManager().deleteMessages();
            Presence presence = new Presence(Presence.Type.available);
            XmppTool.getConnection().sendStanza(presence);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    return msglist;
}

上面代码是获取离线消息

/**
 * 获取在线消息
 *
 * @return
 */
public static void getOnLine(final Context context) {
    Log.i("connectMethod", "getOnLine()");
  /*  DeliveryReceiptManager.getInstanceFor(XmppTool.getConnection()).autoAddDeliveryReceiptRequests();*/

    ChatManager cm = ChatManager.getInstanceFor(XmppTool.getConnection());
    cm.addChatListener(
            new ChatManagerListener() {
                @Override
                public void chatCreated(Chat chat, boolean createdLocally) {
                    chat.addMessageListener(new ChatMessageListener() {
                        @Override
                        public void processMessage(Chat chat, Message message) {
                            if (!TextUtils.isEmpty(message.getBody())) {
                                sendBroadcastMsg(context, message);
                            }
                        }
                    });
                }
            });

}

获取在线消息

/**
 * 发送消息
 *
 * @param to
 * @param msg
 */
public static void sendTalkMsg(String to, Message msg) throws SmackException.NotConnectedException {
    ChatManager chatManager = ChatManager.getInstanceFor(XmppTool.getConnection());
    Chat chat = chatManager.getInstanceFor(XmppTool.getConnection())
            .createChat(to, null);
/*    DeliveryReceiptManager.getInstanceFor(XmppTool.getConnection()).addReceiptReceivedListener(new ReceiptReceivedListener() {
        public void onReceiptReceived(String fromJid, String toJid, String receiptId, Stanza  receipt) {
            Log.i("connectMethod", receipt.toString());
        }
    });*/
    String deliveryReceiptId = DeliveryReceiptRequest.addTo(msg);

    // DeliveryReceiptRequest.addTo(msg);

    chat.sendMessage(msg);
    Log.i("connectMethod", "sendMessage: deliveryReceiptId for this message is: " + deliveryReceiptId);

}

发送与接收消息代码，基本就是这些，项目中是将表情，图片压缩然后转成字节发送，语音也是转成字节，支持文字语音图片的发送。基本实现聊天功能
