闲暇之余,自己写了个简单的即时通讯,基于OpenFire服务器平台。
整个项目包括两个部分,一个是服务器端,一个是android手机端;
一、关于服务器端没什么好说的,下载安装配置即可
推荐下载带jar的程序安装,配置好java_jdk的可以使用压缩包解压安装
OpenFire下载地址:http://www.igniterealtime.org/downloads/index.jsp
顺便下载一个Spark,电脑端通讯,用于和你的安卓手机互发信息。

二、重点介绍一下android端的程序
1、首先要连接到OpenFire服务器,需要一个登陆界面,像这样
连接服务器的代码:
Thread thread = new Thread(new Runnable() { public void run() { try { // 连接服务器 XmppConnection.getConnection().login(userStr, passStr); // 连接服务器成功,更改在线状态 Presence presence = new Presence(Presence.Type.available); XmppConnection.getConnection().sendPacket(presence); handler.sendEmptyMessage(1); } catch (XMPPException e) { XmppConnection.closeConnection(); handler.sendEmptyMessage(2); } } }); thread.start();
XmppConnection类的核心代码
;// 端口 public static String SERVER_HOST = "192.168.1.169";// 服务器地址 public static String SERVER_NAME = "@8nqa3d40s88hspl";// 服务器名称 private static XMPPConnection connection; private static FileTransferManager fileManager; private static void openConnection() { try { if (null == connection || !connection.isAuthenticated()) { XMPPConnection.DEBUG_ENABLED = true; ConnectionConfiguration conConfig = new ConnectionConfiguration( SERVER_HOST, SERVER_PORT, SERVER_NAME); conConfig.setReconnectionAllowed(true); conConfig.setSendPresence(true); conConfig.setSASLAuthenticationEnabled(true); connection = new XMPPConnection(conConfig); connection.connect(); configureConnection(); } } catch (XMPPException e) { } } public static XMPPConnection getConnection() { if (connection == null) { openConnection(); } return connection; } public static void closeConnection() { if(connection != null){ connection.disconnect(); connection = null; } }
2、连接到服务器之后,获取我们的好友,像这样
获取好友列表的代码:
Thread thread = new Thread(new Runnable() { public void run() { try { XMPPConnection conn = XmppConnection.getConnection(); Roster roster = conn.getRoster(); friendList = new ArrayList<Map<String,String>>(); Collection<RosterEntry> entries = roster.getEntries(); HashMap<String, String> map = null; for (RosterEntry entry : entries) { map = new HashMap<String, String>(); map.put("User", entry.getUser()); map.put("Name", entry.getName()); friendList.add(map); } handler.sendEmptyMessage(); } catch (Exception e) { e.printStackTrace(); } } }); thread.start();
3、聊天界面的程序,像这样
Spark聊天界面
接受消息的代码:
private ChatManager chatMan; private Chat newchat;
// 消息监听 chatMan = XmppConnection.getConnection().getChatManager(); newchat = chatMan.createChat(toUserID, null); chatMan.addChatListener(new ChatManagerListener() { @Override public void chatCreated(Chat chat, boolean able) { chat.addMessageListener(new MessageListener() { @Override public void processMessage(Chat chat, Message message) { // 收到来自pc服务器的消息(获取自己好友发来的信息) if (message.getFrom().contains(toUserID)) { if (message.getBody().length() > 0) { // 获取用户、消息、时间、IN String[] args = new String[] { toUserID, message.getBody() }; // 在handler里取出来显示消息 android.os.Message msg = handler .obtainMessage(); msg.what = 1; msg.obj = args; msg.sendToTarget(); } } } }); } });
发送消息的代码:
// 发送消息 String fromUserID = mAppGlobal.getName(); String dateStr = DateTimeUtils.formatDate(new Date()); chatList.add(new Msg(dateStr, fromUserID, content, "OUT")); // 刷新适配器 mAdapter.notifyDataSetChanged(); mListView.setSelection(ListView.FOCUS_DOWN);//刷新到底部 Thread thread = new Thread(new Runnable() { @Override public void run() { try { Message msg = new Message(); msg.setBody(content); // 发送消息 newchat.sendMessage(msg); } catch (XMPPException e) { e.printStackTrace(); } } }); thread.start(); etSend.setText("");
