Android基于XMPP Smack Openfire开发IM【四】初步实现两个客户端通信

本博客要介绍的内容：
Openfire做服务器端，两个客户端：Spark、android模拟器。实现两个客户端之间的通信。

第一步：启动openfire服务器。（这里需要用到两个用户登录，前面的博客中已经说明如何添加用户了。）

第二步：启动Spark客户端，如果您还没有Spark，下载请到： http://www.igniterealtime.org/downloads/index.jsp；安装简单。
我电脑的ip为：192.168.0.124，根据自己的修改。
安装后运行如下下图：

第三步：启动eclipse中的项目（另一个客户端），代码如下：

package com.example.openfiretest;

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

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
	
	
	
	private EditText accountEditText;
	private EditText passwordEditText;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.activity_main);
		accountEditText = (EditText) findViewById(R.id.username);
		passwordEditText = (EditText) findViewById(R.id.password);

		findViewById(R.id.login).setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				String account = accountEditText.getText().toString();
				String password = passwordEditText.getText().toString();
				if (account.equals("") || password.equals("")) {
					Toast.makeText(MainActivity.this, "账号或密码不能为空！",
							Toast.LENGTH_SHORT).show();
				} else {
					ClientConServer ccs = new ClientConServer(MainActivity.this);
					boolean b = ccs.login(account, password);
					// 如果登录成功
					if (b) {
						Toast.makeText(MainActivity.this, "登陆成功！",
								Toast.LENGTH_SHORT).show();
						
						Intent intent = new Intent(MainActivity.this,ChatActivity.class);
						startActivity(intent);
						
						
					} else {
						Toast.makeText(MainActivity.this, "登陆失败！",
								Toast.LENGTH_SHORT).show();
					}
				}
			}
		});
	}
	
}

}

启动后如下图：

第四步：这时，Spark客户端的篮球组中多了一个人。（不清楚组添加、用户添加的请看前面的博客）；
[img]

第五步：手机模拟器发送消息给Spark，输入信息后点击发送，
[img]

[/img]

第六步：Spark给手机模拟器发送消息，输入消息后按Ctrl+Enter发送，手机端把收到的消息，通过控制台打印。

第七步：openfire服务器端发送消息给所有的客户端：
