android端怎么接收openfire服务器发送过来的消息
android客户端接收 openfire 服务器发送来的消息：
客户端代码如下：
Java代码
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();
}
}
}
});
}
}
然后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）：
Java代码
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();
}
});
}
}
}
启动android客户端，进行登录
然后在openfire的管理控制台，会话-工具中发送消息给所有在线用户
即可看到打印信息：在管理控制台发送的消息
