标签： android eclipse smack

基本上，下载了OpenFire Server和Spark Client。 推出了这两款产品，并设法让两个火花用户通过2台笔记本电脑互相聊天。 项目到目前为止是成功的，然后我尝试在eclipse上创建一个应用程序 http://www.javacodegeeks.com/2010/09/xmpp-im-with-smack-for-java.html本教程（我也按照前两部分） 我试过打击和asmack。

头等舱（XmppManager）： 

package montytest.xmppproject;

import java.util.Collection;

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManager;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.SmackConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.ConnectionConfiguration.SecurityMode;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.packet.Presence;
import org.jivesoftware.smack.packet.Presence.Type;

public class XmppManager {

    private static final int packetReplyTimeout = 500; // millis

    private String server;
    private int port;

    private ConnectionConfiguration config;
    private XMPPConnection connection;

    private ChatManager chatManager;
    private MessageListener messageListener;

    public XmppManager(String server, int port) {
        this.server = server;
        this.port = port;
    }

    public void init() throws XMPPException {

        System.out.println(String.format("Initializing connection to server %1$s port %2$d", server, port));

        SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout);

        config = new ConnectionConfiguration(server, port);
        config.setSASLAuthenticationEnabled(false);
        config.setSecurityMode(SecurityMode.disabled);

        connection = new XMPPConnection(config);
        connection.connect();

        System.out.println("Connected: " + connection.isConnected());

        chatManager = connection.getChatManager();
        messageListener = new MyMessageListener();

    }

    public void performLogin(String username, String password) throws XMPPException {
        if (connection!=null && connection.isConnected()) {
            connection.login(username, password);
        }
    }

    public void setStatus(boolean available, String status) {

        Presence.Type type = available? Type.available: Type.unavailable;
        Presence presence = new Presence(type);

        presence.setStatus(status);
        connection.sendPacket(presence);

    }

    public void destroy() {
        if (connection!=null && connection.isConnected()) {
            connection.disconnect();
        }
    }

    public void printRoster() throws Exception {
        Roster roster = connection.getRoster();
        Collection<RosterEntry> entries = roster.getEntries();      
        for (RosterEntry entry : entries) {
            System.out.println(String.format("Buddy:%1$s - Status:%2$s", 
                    entry.getName(), entry.getStatus()));
        }
    }

    public void sendMessage(String message, String buddyJID) throws XMPPException {
        System.out.println(String.format("Sending mesage '%1$s' to user %2$s", message, buddyJID));
        Chat chat = chatManager.createChat(buddyJID, messageListener);
        chat.sendMessage(message);
    }

    public void createEntry(String user, String name) throws Exception {
        System.out.println(String.format("Creating entry for buddy '%1$s' with name %2$s", user, name));
        Roster roster = connection.getRoster();
        roster.createEntry(user, name, null);
    }

    class MyMessageListener implements MessageListener {

        @Override
        public void processMessage(Chat chat, Message message) {
            String from = message.getFrom();
            String body = message.getBody();
            System.out.println(String.format("Received message '%1$s' from %2$s", body, from));
        }

    }

}

第2类（XmppTest）： 

package montytest.xmppproject;

public class XmppTest {

    public static void main(String[] args) throws Exception {

        String username = "testuser1";
        String password = "zaq123";

        XmppManager xmppManager = new XmppManager("jawad", 5222);

        xmppManager.init();
        xmppManager.performLogin(username, password);
        xmppManager.setStatus(true, "Hello everyone");

        String buddyJID = "testuser2";
        String buddyName = "testuser2";
        xmppManager.createEntry(buddyJID, buddyName);

        xmppManager.sendMessage("Hello mate", "testuser2@jawad");

        xmppManager.printRoster();

        boolean isRunning = true;

        while (isRunning) {
            Thread.sleep(50);
        }

        xmppManager.destroy();

    }

}

第3课（开始）： 

package montytest.xmppproject;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class Start extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void launchForm(View button) {

        Intent launchFormActivity = new Intent(this, XmppManager.class); 
        startActivity(launchFormActivity);
}



}

这个类基本上是一个带有通向第一个类的按钮的页面

清单： 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="montytest.xmppproject"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".Start"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".XmppManager"
            android:label="@string/manager" >
        </activity>
        <activity
            android:name=".Xmpptest"
            android:label="@string/test" >
        </activity>
    </application>


</manifest>

并最后在模拟器上运行后使用Logcat：
