android edittext to replace br.readLine()

Question

I'm trying to alter some sample code I found. It's a one on one chat application but all commands are delivered and read by a buffered reader's br.readLine();. I need to alter that and instead of (within a while loop) wait for the user to input text in the console (via br.readLine();), but rather to wait for the enter key on an edit text to be entered.

My code sample that I have so far is :

    String command;
    while(true) {
        try {
            command=br.readLine();
        } catch (IOException e) {
            System.err.println("Error reading command");
            if(pendingChatAccept) {
                sendThroughSocket(Constants.Client.CHAT_DENY, clientSocket, pendingAcceptClient.getIP(), pendingAcceptClient.getPort());    //deny the request
                pendingChatAccept=false;
                pendingAcceptClient=null;
            }
            continue;
        }

        if(pendingChatAccept) {
            char c=command.charAt(0);
            if(c=='y') 
            {
                System.out.println("\nRequest Accepted. Type 'm' to send a message.");
                sendThroughSocket(Constants.Client.CHAT_ACCEPT, clientSocket, pendingAcceptClient.getIP(), pendingAcceptClient.getPort());  //accept the request
                currentChatPartner=pendingAcceptClient;
                currentlyChatting=true;
                pendingChatAccept=false;
                pendingAcceptClient=null;
                msgQueue.clear();   //clear message queue
            } else {
                System.out.println("\nRequest Denied.");
                sendThroughSocket(Constants.Client.CHAT_DENY, clientSocket, pendingAcceptClient.getIP(), pendingAcceptClient.getPort());    //deny the request
                pendingChatAccept=false;
                pendingAcceptClient=null;
            }

So instead of waiting at command=br.readLine();, I'd like to wait till a command has been read from the edittext. Is there a way to do this??

I've been struggling for two days now and just can't seem to get it to work.

My question is: Can I, instead of waiting for command=br.readLine(); to be entered in the system console, wait for an enter key to be pressed and assign the text in the edittext to the command string. — user1397978, Nov 12 '14 at 07:51

 EditText et=new EditText(getApplicationContext());


    et.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub

        }
    });

Hope this will help you

you can use a KeyListener like that:

 final EditText edittext = (EditText) findViewById(R.id.edittext);
    edittext.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            // If the event is a key-down event on the "enter" button
            if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                (keyCode == KeyEvent.KEYCODE_ENTER)) {
              // Perform action on key press
              Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
              return true;
            }
            return false;
        }
    });

i copy the code from this question

And by putting this in the while loop, it will only exit the while loop (as is in my code) when the enter key is pressed? – user1397978 Nov 12 '14 at 07:54
use a boolean parameter to exit the loop (change it from true to false in this method), and while(YOUR_BOOLEAN) – Rami Nov 12 '14 at 08:00
Was thinking something along those lines, but wasn't too sure. Will check it out and let you know and mark as answer when I've attempted it. Thank you for such a quick and helpful response! – user1397978 Nov 12 '14 at 08:20
