问题
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!

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);
what is difference between Smack and asmack? <-- Check This

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

ChatManager chatManager = ChatManager.getInstanceFor(connection);
Chat chat= chatManager.createChat(to, new ChatStateListener() {
@Override
public void stateChanged(Chat chat, ChatState state) {
switch (state){
case active:
Log.d("state","active");
break;
case composing:
Log.d("state","composing");
break;
case paused:
Log.d("state","paused");
break;
case inactive:
Log.d("state","inactive");
break;
case gone:
Log.d("state","gone");
break;
}
}
@Override
public void processMessage(Chat chat, Message message) {
Log.d("processMessage","processMessage");
}
});
use this code.hope so will work

i am using chat state listener :
Chat chat = chatManager.createChat(jid,
new ChatStateChangedListener());
bind the chatstatelistener with each jid like above , then :
public class ChatStateChangedListener implements ChatStateListener {
public ChatStateChangedListener() {
printLog("Chat State Changed Listner Constructor");
}
@Override
public void processMessage(Chat arg0, Message arg1) {
}
@Override
public void stateChanged(Chat chat, ChatState state) {
if (state.toString().equals(ChatState.composing.toString())) {
tvLastSeen.setText("Typing...");
} else if (state.toString().equals(ChatState.paused.toString())) {
tvLastSeen.setText("paused...");
} else {
tvLastSeen.setText("nothing");
}
}
}
}

Create On Class MMessageListener to listen incoming messages
private class MMessageListener implements MessageListener, ChatStateListener {
public MMessageListener(Context contxt) {
}
@Override
public void stateChanged(Chat chat, ChatState chatState) {
mStatus = "Online";
if (ChatState.composing.equals(chatState)) {
mStatus = chat.getParticipant() + " is typing..";
Log.d("Chat State", chat.getParticipant() + " is typing..");
} else if (ChatState.gone.equals(chatState)) {
Log.d("Chat State", chat.getParticipant() + " has left the conversation.");
mStatus = chat.getParticipant() + " has left the conversation.";
} else if (ChatState.paused.equals(chatState)){
Log.d("Chat State", chat.getParticipant() + ": " + chatState.name());
mStatus = "Paused";
}else if (ChatState.active.equals(chatState)){
mStatus = "Online";
}
// do whatever you want to do once you receive status
}
@Override
public void processMessage(Message message) {
}
@Override
public void processMessage(Chat chat, Message message) {
}
}
Add Listener to your chat object
Chat Mychat = ChatManager.getInstanceFor(connection).createChat( "user2@localhost"), mMessageListener);
Send status to receiving user on edittext text change
ChatStateManager.getInstance(connection).setCurrentState(ChatState.composing, Mychat);
This works fine for me.
回答6:
Your or another xmpp client which you use, should sending chat state for You can catch the state.
Like This;
try {
ChatStateManager.getInstance(GlobalVariables.xmppManager.connection).setCurrentState(ChatState.composing, chat);
} catch (XMPPException e) {
e.printStackTrace();
}
or
try {
ChatStateManager.getInstance(GlobalVariables.xmppManager.connection).setCurrentState(ChatState.gone, chat);
} catch (XMPPException e) {
e.printStackTrace();
}

However you can get it from ProcessPacket also. there you will get a Message object, after you can extract xml portion from there and handle them its contain specific chatstate or not.
Message message = (Message) packet;
String msg_xml = message.toXML().toString();
if (msg_xml.contains(ChatState.composing.toString())) {
//handle is-typing, probably some indication on screen
} else if (msg_xml.contains(ChatState.paused.toString())) {
// handle "stopped typing"
} else {
// normal msg
}
now handle as per your requirement.

Just add ChatStateManager after ChatManager intalization:
chatManager = ChatManager.getInstanceFor(getXmpptcpConnection());
ChatStateManager.getInstance(getXmpptcpConnection());
Then you need to add ChatStateListener during createChat(to,chatMesageListener):
chatManager.createChat(message.getTo(), chatMessageListener).sendMessage(message);
private ChatStateListener chatMessageListener = new ChatStateListener() {
@Override
public void stateChanged(Chat chat, ChatState state) {
//State Change composing,active,paused,gone,etc
Log.d(TAG, "ChatStateListener:::stateChanged -> " + chat.toString() + " \n -> " + state.toString());
}
@Override
public void processMessage(Chat chat, Message message) {
//Incoming Message
Log.d(TAG, "ChatStateListener:::processMessage -> " + chat.toString() + " \n -> " + message.toString());
}
};
