onClickListener doesn't working in fragment

Question

public class MainFragment extends Fragment {
    public static final String TAG = MainFragment.class.getSimpleName();
    private static final String ABOUT_SCHEME = "settings";
    private static final String ABOUT_AUTHORITY = "main";
    public static final Uri ABOUT_URI = new Uri.Builder().scheme(ABOUT_SCHEME).authority(ABOUT_AUTHORITY).build();

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

        View v = inflater.inflate(R.layout.mainbutton, container, false);

        return v;
    }

}

According to below link: How to handle button clicks using the XML onClick within Fragments

public class StartFragment extends Fragment implements OnClickListener{


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

        View v = inflater.inflate(R.layout.fragment_start, container, false);

        Button b = (Button) v.findViewById(R.id.StartButton);
        b.setOnClickListener(this);
        return v;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.StartButton:

                /* ... */

                break;
        }
    }
}

source doesn't work too.

Solution

you can NOT access the UI element in onCreateView method - EVER

use onActivityCreated method , thats tell the fragment the activity is fully created and ready to interact

 @Override
        public void onActivityCreated(Bundle savedInstanceState) 
        {
            // TODO Auto-generated method stub
            super.onActivityCreated(savedInstanceState);

            Button b = (Button) v.findViewById(R.id.StartButton);
            b.setOnClickListener(new OnClickListener() {

               @Override
                public void onClick(View v) {
                                    }
                            });
        }

Actually, you can access the UI elements in the onCreateView method. I just tried it, and I get the EditText and do a .setText(...) on it, and it works perfectly. The click event, however, does not work.

Also, where do you get the 'v' varible from?
