使用Android+smack4.1.4+openfire进行IM开发

从smack4.1开始，smack就已经原生支持Android了（再也不需要用asmack了！），然而发现目前国内对最新的smack尤其是4.1之后的介绍比较少。在自己一番折腾后终于测试成功，在这里分享出自己的一些经验，希望初学者能少走弯路，有不足之处还请指正。

程序运行界面：

1.首先是对于openfire环境的搭建，这方面网上示例很多，就不赘述了。

2.相关jar包的下载：

1）smack4.1.4.zip

下载地址：http://download.igniterealtime.org/smack/smack_4_1_4.zip

2）jndi.rar

包含两个jar包：fscontext.jar      providerutil.jar

3）minidns-0.1.3.jar

jxmpp-util-cache-0.4.0-alpha1.jar

jxmpp-core-0.4.1.jar

2和3的jar包在我的示例代码中可以找到，网上也是很容易找到的，就不贴地址了。

3.客户端开发：

新建一个module命名为openfiretest，分别在libs下导入这几个jar包（记得要添加到build path）：

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:weightSum="1"
tools:context="com.piyell.openfiretest.MainActivity">

<EditText
android:hint="输入用户名："
android:id="@+id/et_jid"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:onClick="con"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="connect" />
<Button
android:onClick="login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="login" />
<Button
android:onClick="sendMsg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="sendMsg" />
</LinearLayout>

<ExpandableListView
android:padding="5dip"
android:id="@+id/listview"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="wrap_content">

</ExpandableListView>

</LinearLayout>

新建item_child.xml和item_parent.xml

item_child.xml

<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:gravity="right"
android:id="@+id/tv_child"
android:text="sdfdgdf"
android:textSize="30sp"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TextView>

</LinearLayout>

item_parent.xml

<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/tv_parent"
android:gravity="right"
android:textSize="20sp"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TextView>

</LinearLayout>

连接服务器：

protected boolean conServer() {
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setHost("10.0.2.2");              //设置openfire主机IP
config.setServiceName("pc-piyell");         //设置openfire服务器名称
config.setPort(5222);                   //设置端口号：默认5222
config.setUsernameAndPassword(et_jid.getText(), "123456");    //设置用户名与密码
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);      //禁用SSL连接
config.setSendPresence(true);
config.setDebuggerEnabled(true);
con = new XMPPTCPConnection(config.build());
try {
con.connect();
//Log.e("TAG", connect.getUser());
} catch (Exception e) {
Log.e("TAG", "connect failed!" + e.toString());
e.printStackTrace();
return false;
}
return true;

}

登录部分：

public void login(View view) {

Roster roster = Roster.getInstanceFor(con);

try {
con.login();
} catch (Exception e) {
e.printStackTrace();
}
Log.e("TAG", "login sucess!!");
setPresence(1);

//         设置聊天监听器，监听聊天消息
ChatManager chatm = ChatManager.getInstanceFor(con);
chatm.addChatListener(new ChatManagerListener() {
@Override
public void chatCreated(Chat chat, boolean b) {
if (!b) {           //不是本地创建的会话
chat.addMessageListener(new mChatMsgListener());
}
}
});

/**
*  添加一个分组—— friends
*/
Set<RosterEntry> entries = roster.getEntries();
RosterGroup friends = roster.createGroup("friends");
try {
for (RosterEntry entry : entries) {
friends.addEntry(entry);   /**添加所有好友到friends分组*/

}
} catch (Exception e) {
e.printStackTrace();
}

Log.e("tag", "------群组数=======" + roster.getGroupCount());
Collection<RosterGroup> groups = roster.getGroups();
parentList = new ArrayList<>();

map = new HashMap<>();
for (RosterGroup group : groups) {
parentList.add(group.getName());
List<String> childList = new ArrayList<>();
for (RosterEntry rosterEntry : entries) {
childList.add(rosterEntry.getUser().toString().split("@")[0]);
Log.e("tag", "------Entry=======" + rosterEntry.getUser().toString());
}
map.put(group.getName(), childList);
Log.e("tag", "childlist--------" + map.get(parentList.get(0)).toString());
//            childList.clear();
}
listview.setAdapter(new MyAdapter());

roster.addRosterListener(new RosterListener() {
@Override
public void entriesAdded(Collection<String> collection) {}

@Override
public void entriesUpdated(Collection<String> collection) { }

@Override
public void entriesDeleted(Collection<String> collection) {}

@Override
public void presenceChanged(Presence presence) {
Log.e("TAG", presence.getFrom() + presence);
}
});

}

发送消息：

public void sendMsg(View view) {
ChatManager chatm = ChatManager.getInstanceFor(con);
Chat chat = chatm.createChat("piyell@pc-piyell", new ChatMessageListener() {        //创建与piyell的会话
public void processMessage(Chat chat, Message message) {
System.out.println("Received message: " + message);
}
});
try {
/**
* 发送一条消息给piyell
*/
Message message = new Message("piyell@pc-piyell");
message.addBody(null, "hello");
message.addSubject("favorite color", "red");
//            chat.sendMessage("Hello World!");
chat.sendMessage(message);

} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
}
