There are multiple ways to approach this problem (REST, WebSocket, etc.) I recommend using sockets in this case but I’ll leave it up to you to read up on the pros\/cons of different approaches.<\/p>\n

Socket.IO has a popular Android library for real-time bidirectional event-based communication between two nodes.<\/p>\n

At a high level, to use Socket.IO in your application, you first need to create an instance of it. This will allow you to send and receive messages. For example:<\/p>\n

private Socket mSocket;\nmSocket = IO.socket(\"http:\/\/chat.socket.io\");\nmSocket.connect();\n<\/code><\/pre>\n
To send a message, you need to emit<\/code> to an event. Let’s call this event \"new message\"<\/code>. The following code sends a message using emit<\/code>.<\/p>\n
mSocket.emit(\"new message\", message);\n<\/code><\/pre>\n
In a chat application, you would emit<\/code> a new message when the user clicks the Send button. In your specific case, you need to first get the value of your EditText<\/code> like this:<\/p>\n
mEditText.getText().toString()\n<\/code><\/pre>\n
and then emit<\/code> your message in your Send button’s OnClickListener<\/code>.<\/p>\n
Now that we know how to send a message, we need to know how to receive a message. To receive a message, you need to listen on an event, as opposed to emitting on an event.<\/p>\n
mSocket.on(\"new message\", onNewMessage);\n<\/code><\/pre>\n
The above line will listen for a \"new message\"<\/code> event, and execute the behavior set in onNewMessage<\/code>, which is a Listener<\/code>. In your chat application, you can update a TextView<\/code> with the new message by adding the logic in your Listener<\/code>.<\/p>\n
mTextView.setText(message);\n<\/code><\/pre>\n
To recap, you need to:<\/p>\n
    \n
  1. Create a Socket.IO instance<\/li>\n
  2. When the user clicks Send, grab the text from the EditText<\/code> and emit it<\/li>\n
  3. Listen for a message and update the TextView<\/code><\/li>\n<\/ol>\n
    Details on implementation can be found in Socket.IO’s Android tutorial<\/a>. I highly recommend that you take a look at this as it is a complete, working example.<\/p>\n
    Hope this helps!<\/p>\n<\/p><\/div>\n
