1. 项目简介
做一个类似QQ 的通讯工具,要求有注册、登录、添加好友、添加分组、聊天、退出登录等功能。我用8 张运行效果图来展示我们将要实现的功能。
注意,服务器用的是Openfire,我们可以用Spark 作为另外一个客户端进行测试。
闪屏页进来以后是登录界面,要求记住上次登陆的账号和密码,在界面的右下角有新用户按钮,点击后进入注册界面。注册只需要输入账号和密码即可。账号不能和其他人重复,否则注册不成功。
主界面是一个Activity 绑定3 个Fragment 实现,分别是消息、联系人、动态。
其中消息界面是一个ListView 展出了最近的联系人。点击其中的一个条目可以进入聊天界面。
联系人界面主要是一个ExpandableListView。ExpandableListView 列出了用户组,以及各个组中的好友。点击任意好友可以进入聊天界面。在ExpandableListView 上面有两个图标,分别是新朋友、新群组。点击新朋友弹出一个自定义对话框,在该对话框中输入对方好友的名称,等待对方同意了即可添加为好友。
点击新群组也弹出一个自定义对话框,在该对话框中输入分组名称,则可以创建一个分组。
如果好友不存则添加好友失败,如果分组不存在则创建分组失败。
动态界面主要展示了当前用户的信息,最下面有个退出按钮,点击后退出当前登录,并跳转到登录界面。
聊天界面是一个ListView,该ListView 的条目有两类布局,分别用来表示好友的消息和自己的消息。在最下方的输入框输入文本内容,然后点击发送可以将该消息发送给好友。好友有消息过来也可以直接显示在该界面。
2. 项目搭建
1、下载asmak.jar,是个德国网站
asmack 的版本号从0.x 到现在的4.x 变化比较大。不通过版本差异也比较大。本次我写项目用的是0.8.x 的。
用的是13 年的版本。因为该api 在网上能查到的资料比较多。如果是下一次我再写这个项目我就决定用15 年发布的最新版本的了。
我想看看asmack 公司官网,吧asmack 去掉,想着就是贵公司的网址呢,却得到这样的界面。
2、给工程添加jar
简单极了,只需把下载好的jar 包添加到Android 工程的libs 目录下即可。注意如果eclipse 没有自动将该包添加到环境变量中,我们需要手动添加一下。
3、项目目录结构图
3. 项目实现
3.1 Spark 客户端的下载和安装闪屏界面
新颖的闪屏界面,马老师,学习的目的,我借来用一用哈希望您不用太在意。
我要做的效果是闪屏等待3 秒,然后进入主界面。但是每次都让用户等待3 秒,对于急性子来讲估计会很抓
狂。那怎么办呢,只要是这个界面用户触摸屏幕则立即进入主界面。布局太简单了,不给了。直接给代码。
/**
* 闪屏页面默认等待3s 触摸时直接进入主界面
*
* @author wzy 2015-8-14
*
*/
public class SplashActivity extends Activity {
private static final long DURATION = 3000;
/**
* 保证变量的修改是可见的,但是无法保证变量的原子性
*/
private volatile boolean isEntered = false;
private Thread splashThread = new Thread(new Runnable() {
@Override
public void run() {
SystemClock.sleep(DURATION);
enter();
}
});
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
splashThread.start();
}
private synchronized void enter() {
if (!isEntered) {
isEntered = true;
startActivity(new Intent(SplashActivity.this, LoginActivity.class));
finish();
}
}
@Override
public boolean onTouchEvent(MotionEvent event) {
enter();
return true;
}
}
3.2 登录
登录界面布局很简单。如果写不出来就没必要往下看了。登录的核心代码:
mXmppConnection.login(name, pwd);
activity_login.xml
LoginActivity 和RegistActivity 都继承自BaseActivity。因此这里先把BaseActivity 的代码列出。
BaseActivity.java
public class XmppConnectionManager {
private static XmppConnectionManager instance = null;
//私有化构造函数
private XmppConnectionManager() {
}
/**
* 获取该对象
* @return
*/
public static XmppConnectionManager getInstance() {
if (instance == null) {
instance = new XmppConnectionManager();
}
return instance;
}
/**
* 执行初始化脚本
* @return
*/
public XMPPConnection init() {
/**
* 创建连接配置对象
* 第一个参数是Openfire 服务器地址
* 第二个参数是Openfire 服务器断开号,默认是5222
* 我们可以把这两个参数配置的清单文件中,也可以写死在代码中
*/
ConnectionConfiguration connectionConfig = new
ConnectionConfiguration(Const.XMPP_HOST,Const.XMPP_PORT);
/**
* 不使用SAL 安全验证
*/
connectionConfig.setSASLAuthenticationEnabled(false);
/**
* 设置TLS 安全模式
*/
connectionConfig.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);
// 允许自动连接
connectionConfig.setReconnectionAllowed(true);
// 允许登陆成功后更新在线状态
connectionConfig.setSendPresence(true);
//设置为debug 模式,该模式可以在控制台看到接收和发送的xmpp 协议
connectionConfig.setDebuggerEnabled(true);
// 收到好友邀请后同意添加为好友的模式,有三种,manual 表示需要经过同意,accept_all 表示不经同意自动
为好友,reject_all 拒绝加为好友邀请
Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.accept_all);
/**
* 该配置时为了解决asmack 的一个bug 或者说弥补一个不足之处。不用细细追究。
*/
configure(ProviderManager.getInstance());
//创建一个连接对象,参数为配置对象
XMPPConnection connection = new XMPPConnection(connectionConfig);
return connection;

在上面的代码中我们将登陆成功后获取的connection 对象设置到了Application 中,这里用到了自定义的
Application,并且在清单文件中已经配置。
QQApplication.java
public class QQApplication extends Application {
private XMPPConnection mXmppConnection;
@Override
public void onCreate() {
super.onCreate();
}
public XMPPConnection getXmppConnection(){
return mXmppConnection;
}
public void setXmppConnection(XMPPConnection xmppConnection){
this.mXmppConnection = xmppConnection;
}
}
AndroidManifest.xml
清单文件中高亮显示的两个部分,因为需要连接服务器,因此需要联网权限。
3.3 注册
注册功能核心代码:
//创建注册对象,用于封装注册参数
Registration registration = new Registration();
//设置注册属于设置属性,因此这里设置类型为set
registration.setType(Type.SET);
//设置用户名和密码
registration.setUsername(name);
registration.setPassword(pwd);
/**
* 注册信息封装好之后其实就可以发送了可以直接调用
* mXmppConnection.sendPacket(registration);方法
* 但是上面的方法并没有返回值,注册是否成功我们不清楚
* 因此我们需要开启一个数据包收集器来手机服务返回的信息
*
*/
//定义一个数据包过滤器
/**
* AndFilter 是一个组合过滤器,形参是可变参数,可以传递多种PacketFilter 的子类
* 我们需要要过滤的原则是根据注册数据包的id 和数据包类型
*
*/
PacketFilter filter = new AndFilter(new
PacketIDFilter(registration.getPacketID()), new PacketTypeFilter(IQ.class));
//创建一个数据包收集器,形参为数据包过滤器
PacketCollector collector = mXmppConnection.createPacketCollector(filter);
// 这个api 并没有提供最简单的regist 方法。而是用了很负责的api,用户体验不佳。
mXmppConnection.sendPacket(registration);
/**
* 上面的代码已经发送过注册数据包了,接下来我们就可以收集服务器的返回值了
* 形参为网络超时时间默认5s
*/
Packet packet = collector.nextResult(SmackConfiguration.getPacketReplyTimeout());
/**
* 将数据包强转为IQ,因为我们的过滤器已经限定了是IQ 类型的数据包才收集,因此我们
可以大胆的强转
*/
IQ result = (IQ) packet;
//收集到数据后就可以将收集器关闭了,不然可能把其他符合条件的数据也收集来了
collector.cancel();
//如果IQ 为空则代表请求失败这里代码我写的不太好了,应该先判断packet 是否为空,
不为空再强转,这样才能避免空指针
if (result == null) {
Message message = Message.obtain();
message.what = RESULT_CANCELED;
handler.sendMessage(message);
return;
//如果返回的数据类型为IQ.Type.Result 则代表成功
} else if (result.getType().equals(IQ.Type.RESULT)) {

message.what = RESULT_OK;
handler.sendMessage(message);
return;
} else {

//否则代表失败,那么我们就收集失败码
int errorCode = result.getError().getCode();
message.what = RESULT_CANCELED;
//如果失败码是409,那么代表用户已经被注册
if (409 == errorCode) {
message.obj = "该用户名已经被注册,请换一个名字吧";

return;

} catch (Exception e) {
e.printStackTrace();
Looper.prepare();
Toast.makeText(application, "注销失败"+e, 0).show();
Looper.loop();
getActivity().finish();
return ;
}
}
}

3.6 获取联系人功能
联系人界面对应的是ContactFragment,这个界面包含了获取联系人,添加新朋友,添加新组群等三个功能。
我先将上面三个功能的核心代码列出来,然后在把ContactFragment.java 代码给列出出来。
获取到分组,然后每个分组里面有联系人。界面用的是一个ExpendableListView。
获取联系人核心代码:
thread = new Thread(new Runnable() {
@Override
public void run() {
FragmentActivity activity = getActivity();
if (activity==null) {
return ;
}
QQApplication application = (QQApplication) activity.getApplication();
xmppConnection = application.getXmppConnection();
Roster roster = xmppConnection.getRoster();
Collection groups = roster.getGroups();
Iterator iterator = groups.iterator();
rosterGroups.clear();
while (iterator.hasNext()) {
RosterGroup rosterGroup = (RosterGroup) iterator.next();
rosterGroups.add(rosterGroup);
}
handler.sendEmptyMessage(1);
}
});
添加新朋友核心代码:
public static boolean addUsers(Roster roster, String userName, String name, String groupName) {
try {
roster.createEntry(userName, name, new String[]{groupName});
return true;
} catch (Exception e) {
e.printStackTrace();
Log.e("XmppUtils", "添加好友异常:" + e.getMessage());
}
}
添加新群组核心代码:
public static RosterGroup addGroup(Roster roster, String groupName) {
try {
return roster.createGroup(groupName);
} catch (Exception e) {
e.printStackTrace();
Log.e("XmppUtils", "创建分组异常:" + e.getMessage());
return null;
}
}

3.7 聊天功能
聊天界面是一个ListView,这个ListView 有两个布局一个是我发送的消息,另外一个是好友发送的消息。
聊天功能核心代码:
if (chatManager==null) {
//获取聊天管理器
chatManager = xmppConnection.getChatManager();
}
if (chat==null) {
//创建聊天,并制定消息监听器用于监听好友发送的消息
chat = chatManager.createChat(user, messageListener);
}
chat.sendMessage(msg);
private MessageListener messageListener = new MessageListener() {
@Override
public void processMessage(Chat chat, Message message) {
String body = message.getBody();
if (TextUtils.isEmpty(body)) {
return ;
}
com.itheima.qq.bean.Message message2 =new com.itheima.qq.bean.Message();
message2.setBody(body);
message2.setTime(TimeUtils.getNowTimeString());
message2.setFrom(user);
message2.setTo(xmppConnection.getUser());
dataList.add(message2);
MessageDB.putMessage(message2);
android.os.Message message3 = android.os.Message.obtain();
message3.what=2;
handler.sendMessage(message3);
}
};
activity_chat.xml
list_item_chat_me.xml
该布局是ListView 中“自己”发送消息时使用的布局。

3.8 消息界面
SessionFragment 布局就是一个ListView 十分的简单,因此就不给出了。

3.9 启动服务监听消息
