How to know Typing Status in XMPP openfire using Smack

Question

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!

Answer 1

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);

finally I got the solution. I need to use chat listener along with chat manager and also I need to use in built sendcomposingnotification function. No need to use Messageeventrequestlistener interface or any other custom class for this. I added the following lines,,

connection.getChatManager().addChatListener(new ChatManagerListener() {

            @Override
            public void chatCreated(final Chat arg0, final boolean arg1) {
                // TODO Auto-generated method stub

                arg0.addMessageListener(new MessageListener()
                {

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

                        Log.d("TYpe Stat",title[0] + " is typing......");
                        Toast.makeText(getApplicationContext(),title[0] + " is typing......",Toast.LENGTH_SHORT).show();
                    }



                    }
                }); 
            }
        });

and also need to send notification like this..

mem.sendComposingNotification(etRecipient.getText().toString(), message.getPacketID());
        System.out.println("Sending notification");

where mem is type of MessageEventManger. Ref: http://www.igniterealtime.org/builds/smack/docs/latest/javadoc/org/jivesoftware/smackx/MessageEventManager.html
