Android基于XMPP Smack Openfire开发IM 【二】获取好友列表

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：
