Android基于XMPP Smack Openfire开发IM【三】客户端接收服务器发送的消息

第一,客户端代码如下:
MainActivity未做改动,与之前两篇一样
- 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();
- } else {
- Toast.makeText(MainActivity.this, "登陆失败!",
- Toast.LENGTH_SHORT).show();
- }
- }
- }
- });
- }
- }
下面的这个类在第二篇的基础上,在登陆以后添加一个监听消息的监听器,用来监听收到的消息(代码89、90行):
- package com.example.openfiretest;
- import java.util.Collection;
- 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.Roster;
- import org.jivesoftware.smack.RosterEntry;
- import org.jivesoftware.smack.RosterGroup;
- import org.jivesoftware.smack.XMPPConnection;
- import org.jivesoftware.smack.XMPPException;
- import org.jivesoftware.smack.packet.Message;
- import android.content.Context;
- import android.content.Intent;
- import android.os.Handler;
- 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;
- }
- //这里收到消息后,通过广播将消息发送到需要的地方.哈哈,既然收到了服务器发送来的信息,如何处理自己决定。
- private Handler handler = new Handler(){
- public void handleMessage(android.os.Message m) {
- Message msg=new Message();
- msg=(Message) m.obj;
- //把从服务器获得的消息通过广播发送
- Intent intent = new Intent("org.yhn.mes");
- String[] message=new String[]{
- msg.getFrom(),
- msg.getBody()};
- System.out.println("==========收到服务器消息 From==========="+message[0].toString());
- System.out.println("==========收到服务器消息 Body==========="+message[1].toString());
- intent.putExtra("message", message);
- context.sendBroadcast(intent);
- };
- };
- 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);
- //获取用户组、成员信息。
- 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());
- 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==========");
- //在登陆以后应该建立一个监听消息的监听器,用来监听收到的消息:
- ChatManager chatManager = connection.getChatManager();
- chatManager.addChatListener(new MyChatManagerListener());
- return true;
- } catch (XMPPException e) {
- e.printStackTrace();
- }
- return false;
- }
- /** message listener*/
- class MyChatManagerListener implements ChatManagerListener {
- public void chatCreated(Chat chat, boolean arg1) {
- chat.addMessageListener(new MessageListener(){
- public void processMessage(Chat arg0, Message msg) {
- /**通过handler转发消息*/
- android.os.Message m=handler.obtainMessage();
- m.obj=msg;
- m.sendToTarget();
- }
- });
- }
- }
- }
第二,启动android客户端,进行登录。

第三、在openfire的管理控制台,会话-工具中发送消息给所有在线用户,如下图

第四、打印信息如下:
