openfire+smack收发消息

一、在openfire+smack下，制作简单的AndroidApp可以收发消息

1、openfire和smack配置这里就不赘述了，网上配置教程一堆；

2、直接开始写代码，聊天主界面布局文件chat.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/chat_bg"
android:orientation="vertical" >

<TextView
android:id="@+id/chat_text"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
></TextView>

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dp"

android:orientation="horizontal"
android:background="@drawable/linearlayout_boder"
>
<ImageView
android:layout_width="45dp"
android:layout_height="45dp"
android:background="@drawable/id"/>
<EditText
android:id="@+id/edit_chat"
android:layout_width="220dp"
android:layout_height="40dp"
android:inputType="text"
/>
<ImageView
android:layout_width="45dp"
android:layout_height="45dp"
android:background="@drawable/action_add"/>
<ImageView
android:id="@+id/img_x"
android:layout_width="45dp"
android:layout_height="45dp"
android:background="@drawable/x"/>

</LinearLayout>
</LinearLayout>

3、创建连接服务器类ConnectServer.java。

package com.example.eric_jqm_chat;

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;

/*
*@author  Eric
*@create date 2015-8-21上午9:22:14
*/
public class ConnectServer {
public XMPPConnection ConnectServer() {
ConnectionConfiguration connectionConfig = new ConnectionConfiguration(
"192.168.226.41", 5222);//服务器IP和默认端口号5222
connectionConfig.setReconnectionAllowed(true);
connectionConfig.setSendPresence(true);

XMPPConnection con = new XMPPConnection(connectionConfig);
try {
con.connect();
System.out.println("连接成功！！");
// Toast.makeText(getApplicationContext(), "连接成功", 0).show();
} catch (XMPPException e) {
System.out.println("连接发生错误！！");
}
return con;
}
}

4、收发用户消息的ChatActivity.java，可以在pc端使用Spark与app进行聊天。

package com.example.eric_jqm_chat;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManagerListener;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;

/*
*@author  Eric
*@create date 2015-8-25下午8:51:17
*/

public class ChatActivity extends Activity {
private TextView text_chat;
private EditText edit_chat;
private ImageView img_x;
private XMPPConnection con = new ConnectServer().ConnectServer();//实例化连接对象
private String str_text,name,password,friend,sendMsg;
private ChatHandler handler;
private SimpleDateFormat sf = new SimpleDateFormat("HH:mm");//获取系统时间自定义格式

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.chat);//加载布局文件

text_chat = (TextView) findViewById(R.id.chat_text);
img_x = (ImageView) findViewById(R.id.img_x);
edit_chat = (EditText) findViewById(R.id.edit_chat);

//点击图片，发送编辑框里的内容给friend用户
img_x.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
sendMsg = edit_chat.getText().toString();//获取EditText中的文本

Chat chat = con.getChatManager().createChat(friend+"@"+"eric-pc", null);//建立聊天
try {
chat.sendMessage(sendMsg);//发送消息
} catch (XMPPException e) {
e.printStackTrace();
}

edit_chat.setText(null);

if(str_text==null){
str_text = "("+sf.format(new Date())+")"+"你对他说："+sendMsg;
}else{
str_text = str_text + "\n" +"("+sf.format(new Date())+")"+"你对他说："+sendMsg;
}
text_chat.setText(str_text);//将聊天内容加入到主界面TextView中
}
});

name = getIntent().getStringExtra("name");
password = getIntent().getStringExtra("password");//获取前一个Activity传来的用户名和密码
try {
con.login(name, password);//登录用户
} catch (XMPPException e) {
e.printStackTrace();
}
<p>		</p><p>
</p><p><span style="white-space:pre">		</span>//登录后的用户接收消息的副线程</p>

Thread thread = new Thread(new Runnable(){

@Override
public void run() {
//接收用户发来的消息
con.getChatManager().addChatListener(new ChatManagerListener() {

@Override
public void chatCreated(Chat chat, boolean arg1) {
chat.addMessageListener(new MessageListener() {

@Override
public void processMessage(Chat chat, Message msg) {
//截取发来信息的用户的用户名
friend = msg.getFrom();
friend = friend.substring(0, friend.indexOf("@"));

//处理消息内容，实际上msg.getBody就是消息内容，为了显示美观，做了简单处理
if(msg.getBody()!= null){
if(str_text==null){
str_text ="("+sf.format(new Date())+")"+friend+"对你说:"+msg.getBody()+"\n";
android.os.Message m = new android.os.Message();
Bundle b= new Bundle();
b.putString("msg", str_text);
m.setData(b);
handler.sendMessage(m);//将获取的消息内容发送给handler

}else{
str_text =str_text+"("+sf.format(new Date())+")"+friend+"对你说:"+msg.getBody()+"\n";
android.os.Message m = new android.os.Message();
Bundle b= new Bundle();
b.putString("msg", str_text);
m.setData(b);
handler.sendMessage(m);
}
}

}
});
}
});

}

});

thread.start();//启动接收消息的副线程
handler = new ChatHandler();//实例化Handler

}

public class ChatHandler extends Handler{
@Override
public void handleMessage(android.os.Message msg) {
super.handleMessage(msg);

Bundle b = msg.getData();
String ChatHandler = b.getString("msg");

text_chat.setText(ChatHandler);//将接收到的消息设置到主界面
}
}
}

效果图：
