第一步，在openfire后台中创建一些用户，并添加两个组。我这里添加的两个组是：我的聊天小组、篮球。

第二步，编辑组，把用户添加到组中。

第三步，客户端代码如下：
（MainActivity 同上篇，未做修改）
package com.example.openfiretest;import android.os.Bundle;import android.app.Activity;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(); // startActivity(new // Intent(LoginActivity.this,MainActivity.class)); // MainActivity.account=account; } else { Toast.makeText(MainActivity.this, "登陆失败！", Toast.LENGTH_SHORT).show(); } } } }); }}下面的比上篇的略做修改，添加获取组个数、组名称、组成员名称等代码：
package com.example.openfiretest;import java.util.Collection;import org.jivesoftware.smack.ConnectionConfiguration;import org.jivesoftware.smack.Roster;import org.jivesoftware.smack.RosterEntry;import org.jivesoftware.smack.RosterGroup;import org.jivesoftware.smack.XMPPConnection;import org.jivesoftware.smack.XMPPException;import android.content.Context;import android.util.Log;import android.widget.Toast;public class ClientConServer { private static int PORT=5222; private Context context; public ClientConServer(Context context){ this.context=context; } public boolean login(String a,String p){ ConnectionConfiguration config = new ConnectionConfiguration("192.168.0.124", PORT); /** 是否启用安全验证 */ config.setSASLAuthenticationEnabled(false); /** 是否启用调试 */ //config.setDebuggerEnabled(true); /** 创建connection链接 */ XMPPConnection connection = new XMPPConnection(config); try { /** 建立连接 */ connection.connect(); /** 登录*/ connection.login(a, p); /** 开启读写线程，并加入到管理类中*/ //ClientSendThread cst=new ClientSendThread(connection); //cst.start(); //ManageClientThread.addClientSendThread(a, cst); System.out.println("======开始获取组及用户=========="); Roster roster = connection.getRoster(); Collection<RosterGroup> entriesGroup = roster.getGroups(); System.out.println("组的个数："+entriesGroup.size()); for(RosterGroup group: entriesGroup){ Collection<RosterEntry> entries = group.getEntries(); System.out.println("=========groupName==="+group.getName()); for (RosterEntry entry : entries) { //Presence presence = roster.getPresence(entry.getUser()); //Log.i("---", "user: "+entry.getUser()); Log.i("TAG", "name: "+entry.getName()); System.out.println("组成员名字："+entry.getName()); //Log.i("---", "tyep: "+entry.getType()); //Log.i("---", "status: "+entry.getStatus()); //Log.i("---", "groups: "+entry.getGroups()); } } System.out.println("======结束获取组及用户=========="); return true; } catch (XMPPException e) { e.printStackTrace(); } return false; }}第四步：启动android客户端进行用户登陆：
