Runnable Handler not executing inside fragment. Could not start a runnable

Question

I have a runnable inside a fragment. The runnable is meant to update the textviews as well as receive input using buttons. But the program does not enter even once inside the runnable.

Please help. What am I doing wrong. Thanks. The code is as follows. I have buttons and textviews inside the runnable.

public class TodayFragment extends Fragment {
//initialisations

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

//UI initialisations

Handler mHandler = new Handler();
Runnable mTicker = new Runnable() {
            @Override
            public void run() {

//user interface interactions and updates on screen

    mHandler.postDelayed(mTicker, 1000);


   mTicker.run();

 }

Answer 1

try this change

mTicker = new Runnable() {
        public void run() {

         //user interface interactions and updates on screen

           mHandler.postDelayed(mTicker, 1000);

        }
    };
    mTicker.run();
