why i can't get the getActivity.runOnUiThread?

[armadeas]

I'm create and put this
private Emitter.Listener onNewMessage = new Emitter.Listener(){
bla bla bla
}
in my app(MainActivity) same as in tutorial at http://socket.io/blog/native-socket-io-and-android/,
but why i have error in getActivity().runOnUiThread(new Runnable() { ?
when i ctrl + space, there is no getActivity

anyone can help me?
it's my first time combine speech to text and socket io

[armadeas]

and when i put this in onCreate after mSocket.connect();

    if(mSocket.connected()){
        txtSpeechInput.setText("Connected");
    }else{
        txtSpeechInput.setText("Not Connected");
    }

This is because you are writing getActivity method inside
Emitter.Listener() object, where as getActivity() method is avaiable in
Acitivity class.

Solution: Use .this.getActivity() method inside
Emmiter.Listener

e.g.
class MainActivity extends Activity{
//Blah Blah

private Emitter.Listener onNewMessage = new Emitter.Listener(){
bla bla bla

MainActivity.this.getAcitivity().runOnUiThread(new Runnable() { //code}
}

}

Where did you get the error actually on your code?

[armadeas]

@nkzawa the error in addMessage method. But it's no problem, because now i change all of my code.
i use your program for base of my code. (https://github.com/nkzawa/socket.io-android-chat)
i put some code from http://www.androidhive.info/2014/07/android-speech-to-text-tutorial/

There's no error but why method attemptSend() is can't be called?

if you want to see my code, here it is http://pastebin.com/GtcBNP9k
i want to put attemptSend() after line number 202.
But, why it's not working? :(

sorry if my english is bad or wrong.

[armadeas]

so it will look like this

switch (requestCode) {

        case REQ_CODE_SPEECH_INPUT: {
            if (resultCode == Activity.RESULT_OK && null != data) {

                ArrayList<String> result = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                        mInputMessageView.setText(result.get(0));
                        attemptSend()
                        Toast.makeText(getActivity().getApplicationContext(), "YOLO" , Toast.LENGTH_SHORT).show();
            }
            break;
        }

    }

i want to input the chat but with voice.
so first, i press the button, then the google speech input show -> i'm speaking -> then what i say is send to the chat

[nkzawa]

Umm, I don't get your problem. Maybe it would be better to ask on stackoverflow.

[armadeas]

umm, ok ok.
Thanks sir :D

[armadeas]

@nkzawa
what it is for sir?

mInputMessageView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView v, int id, KeyEvent event) {
                if (id == R.id.send || id == EditorInfo.IME_NULL) {
                    attemptSend();
                    return true;
                }
                return false;
            }
        });

[nkzawa]

@armadeas it's for sending a message when an user pressed a specific key on keyboard.
