如何使用Smack知道XMPP openfire中的输入状态 [英] How to know Typing Status in XMPP openfire using Smack

问题描述

我正在使用Openfire XMPP服务器开发聊天应用程序.我可以在两个用户之间发短信聊天.但是我想知道有人输入消息时的键入状态.所以我创建了一个类:-

public class typingStatus implements ChatStateListener {

    @Override
    public void processMessage(Chat arg0, Message arg1) {
        // TODO Auto-generated method stub

    }

    @Override
    public void stateChanged(Chat arg0, ChatState arg1) {
        // TODO Auto-generated method stub
        System.out.println(arg0.getParticipant() + " is " + arg1.name());

    }

}

但是我很困惑，所以它将如何工作?我知道我需要在侦听器中可以使用的数据包.但是我找不到那个包.

请任何人建议，它将如何工作?

还有Smack和asmack有什么区别?

谢谢！

解决方案

要启用ChatStateListener，您需要创建一个自定义的MessageListener类

public class MessageListenerImpl implements MessageListener,ChatStateListener  {

    @Override
    public void processMessage(Chat arg0, Message arg1) {
        System.out.println("Received message: " + arg1);

    }

    @Override
    public void stateChanged(Chat arg0, ChatState arg1) {
        if (ChatState.composing.equals(arg1)) {
            Log.d("Chat State",arg0.getParticipant() + " is typing..");
        } else if (ChatState.gone.equals(arg1)) {
            Log.d("Chat State",arg0.getParticipant() + " has left the conversation.");
        } else {
            Log.d("Chat State",arg0.getParticipant() + ": " + arg1.name());
        }

    }

}

然后创建MessageListener对象

MessageListener messageListener = new MessageListenerImpl();

然后将其传递给create chat方法

Chat newChat = chatmanager.createChat(jabber_id_of_friend, messageListener);

Smack和asmack有什么区别?<-选中此

I am developing chat application by using Openfire XMPP server. I can text chat between two user. But i want to know Typing status when some one is typing message. So i created a class :-

public class typingStatus implements ChatStateListener {

    @Override
    public void processMessage(Chat arg0, Message arg1) {
        // TODO Auto-generated method stub

    }

    @Override
    public void stateChanged(Chat arg0, ChatState arg1) {
        // TODO Auto-generated method stub
        System.out.println(arg0.getParticipant() + " is " + arg1.name());

    }

}

But i am confuse so that How will it work? I know that i need a packet where i can it in Listener. But i am unable to find that packet.

Please any one suggest, How will it work?

and also what is difference between Smack and asmack?

Thank you!

解决方案

To enable ChatStateListener you need to create a custom MessageListener Class

public class MessageListenerImpl implements MessageListener,ChatStateListener  {

    @Override
    public void processMessage(Chat arg0, Message arg1) {
        System.out.println("Received message: " + arg1);

    }

    @Override
    public void stateChanged(Chat arg0, ChatState arg1) {
        if (ChatState.composing.equals(arg1)) {
            Log.d("Chat State",arg0.getParticipant() + " is typing..");
        } else if (ChatState.gone.equals(arg1)) {
            Log.d("Chat State",arg0.getParticipant() + " has left the conversation.");
        } else {
            Log.d("Chat State",arg0.getParticipant() + ": " + arg1.name());
        }

    }

}

Then you create MessageListener object

MessageListener messageListener = new MessageListenerImpl();

And then pass this in the create chat method

Chat newChat = chatmanager.createChat(jabber_id_of_friend, messageListener);
