即时通讯系列阅读
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
Paste_Image.png
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。
Paste_Image.png
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
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/login_background" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/login_background"
android:orientation="vertical" >
<ImageView
android:id="@+id/iv_touxiang"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="40dp"
android:contentDescription="@null"
android:src="@drawable/login_image" />
<EditText
android:id="@+id/et_name"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="30dp"
android:background="#FFFFFF"
android:hint="请输入账号"
android:paddingLeft="5dp"

android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="#FFFFFF"
android:hint="请输入密码"
android:inputType="textPassword"
android:paddingLeft="5dp"
android:textSize="20sp" />
<Button
android:id="@+id/btn_login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="15dp"
android:background="@color/title_layout"
android:onClick="login"
android:text="登录"
android:textColor="#FFFFFF"
android:textSize="20sp" />
</LinearLayout>
<Button
android:id="@+id/register"
android:layout_width="100dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginRight="20dp"
android:background="@drawable/register_user_btn"
android:text="新用户"
android:onClick="gotoRegist"
android:textColor="@color/blue"
android:textSize="16sp" />
</RelativeLayout>
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() {

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<br>
* 第一个参数是Openfire 服务器地址<br>
* 第二个参数是Openfire 服务器断开号，默认是5222<br>
* 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);

connectionConfig.setSASLAuthenticationEnabled(false);

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);

// 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);

//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，

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)) {

3.5 退出登录
退出登录的功能是在动态中实现的。消息、联系人、动态都是Fragment 实现的。核心代码：
if (xmppConnection.isConnected()) {
if (xmppConnection.isAuthenticated()) {
try {
xmppConnection.disconnect();
} catch (Exception e) {
e.printStackTrace();
Looper.prepare();
Toast.makeText(application, "注销失败"+e, 0).show();
Looper.loop();
getActivity().finish();
return ;
}
}
}
DongtaiFragment.java
public class DongtaiFragment extends Fragment {
private TextView tv_name;
private RelativeLayout rl_logout;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState) {
View view = initView();
return view;
}
private View initView() {
View view = View.inflate(getActivity(), R.layout.fragment_dongtai2, null);
SharedPreferences sp = getActivity().getSharedPreferences("config",
Context.MODE_PRIVATE);
String name = sp.getString("name", "");
tv_name = (TextView) view.findViewById(R.id.tv_name);
rl_logout = (RelativeLayout) view.findViewById(R.id.rl_logout);
if (!TextUtils.isEmpty(name)) {
tv_name.setText(name);
}
rl_logout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
final QQApplication application = (QQApplication)
getActivity().getApplication();
final XMPPConnection xmppConnection = application.getXmppConnection();
new Thread(new Runnable() {
@Override
public void run() {
if (xmppConnection.isConnected()) {
if (xmppConnection.isAuthenticated()) {
try {
xmppConnection.disconnect();
} catch (Exception e) {
e.printStackTrace();
Looper.prepare();
Toast.makeText(application, "注销失败"+e, 0).show();
Looper.loop();
getActivity().finish();
return ;
}
Looper.prepare();
Toast.makeText(application, "注销成功", 0).show();
getActivity().startActivity(new Intent(application,
LoginActivity.class));
getActivity().finish();
Looper.loop();
}
}
}
}).start();
}
});
return view;
}
}
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<RosterGroup> groups = roster.getGroups();
Iterator<RosterGroup> 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;
}
}

}
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);

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。
SessionFragment.java
public class SessionFrament extends Fragment {
private ListView lv_session;
private ArrayList<Session> dataList = new ArrayList<Session>();
private MyAdapter adapter = new MyAdapter();
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState) {
View view = initView();
initData();
return view;
}
private View initView() {
View view = View.inflate(getActivity(), R.layout.fragment_session, null);
lv_session = (ListView) view.findViewById(R.id.lv_session);
return view;
}
public void initData() {
lv_session.setAdapter(adapter);
ArrayList<Session> sessions = SessionDB.getSessions();
if (sessions != null && sessions.size() > 0) {
dataList = sessions;
adapter.notifyDataSetChanged();
}
lv_session.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
String user = dataList.get(position).getUsr();
Toast.makeText(getActivity(), user, 0).show();
Intent chatIntent = new Intent(getActivity(), ChatActivity.class);
chatIntent.putExtra("user", user);
startActivity(chatIntent);
}
});
};
class MyAdapter extends BaseAdapter {
@Override
public int getCount() {
return dataList.size();
}
@Override
public Object getItem(int position) {
return dataList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = View.inflate(getActivity(), R.layout.list_item_session, null);

convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
Session session = dataList.get(position);
viewHolder.tv_msg.setText(session.getMsg());
viewHolder.tv_time.setText(session.getTime());
// 到底是from 还是to
viewHolder.tv_name.setText(session.getUsr());
return convertView;
}
}
@Override
public void onResume() {
super.onResume();
if(adapter!=null){
adapter.notifyDataSetChanged();
}
SessionDB.setListener(new SessionListener() {
@Override
public void onChange() {
if (adapter!=null) {
adapter.notifyDataSetChanged();

}
});
}
static class ViewHolder {
TextView tv_name;

3.9 启动服务监听消息
当用户登录成功的时候在后台开启一个服务，用于监听主动发过来的消息。
ChatService.java
public class ChatService extends Service {
private static QQApplication application;
private static NotificationManager notificationManager;
private ChatManager chatManager;
private MessageListener messageListener = new MessageListener() {
public void processMessage(Chat chat, Message message) {
if (TextUtils.isEmpty(message.getBody())) {
return ;
}
Session session = new Session();
session.setMsg(message.getBody());
String from = message.getFrom();
if (from.endsWith("/Spark")) {
from = from.substring(0, from.length()-"/Spark".length());
}
session.setFrom(from);
session.setTo(message.getTo());
session.setUsr(from);
session.setTime(TimeUtils.getNowTimeString());
SessionDB.updateSession(session);
com.itheima.qq.bean.Message message2 = new com.itheima.qq.bean.Message();
message2.setBody(message.getBody());
message2.setFrom(from);
message2.setTo(message.getTo());
message2.setTime(TimeUtils.getNowTimeString());
MessageDB.putMessage(message2);
android.os.Message msg = android.os.Message.obtain();
msg.obj = message;
handler.sendMessage(msg);
}
};
private ChatManagerListener chatManagerListener = new ChatManagerListener() {
@Override
public void chatCreated(Chat chat, boolean createdLocally) {
if (!createdLocally) {
chat.addMessageListener(messageListener);
}
}
};
private Handler handler = new Handler() {
public void handleMessage(android.os.Message msg) {
Notification notification = new Notification(R.drawable.kkj, "收到新消息",
SystemClock.uptimeMillis());
notification.flags = Notification.FLAG_AUTO_CANCEL;
Intent intent = new Intent(ChatService.this, ChatActivity.class);
Message message = (Message)msg.obj;
String from = message.getFrom();
if (from.endsWith("/Spark")) {
from = from.substring(0, from.length()-"/Spark".length());
}
intent.putExtra("user",from);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(ChatService.this, 1,intent,
PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(ChatService.this, "新消息", "请注意查收",
pendingIntent);
notificationManager.notify(2, notification);
};
};
public IBinder onBind(Intent intent) {
return null;
}
public void onCreate() {
super.onCreate();
application = (QQApplication) getApplication();
notificationManager = (NotificationManager)
ChatService.this.getSystemService(Context.NOTIFICATION_SERVICE);
}
public int onStartCommand(Intent intent, int flags, int startId) {
initListener();
return super.onStartCommand(intent, flags, startId);
}
private void initListener() {
XMPPConnection xmppConnection = application.getXmppConnection();
if (xmppConnection==null) {
return;
}
chatManager = xmppConnection.getChatManager();
Toast.makeText(this, "服务已经开启", 0).show();
chatManager.addChatListener(chatManagerListener);
}
}
