I think the issue was by ths following , Because creating SimpleAdapter Adapter object from Fragment,so pass getActivity() instead of BusTimetableActivity.this as first paramter to SimpleAdapter constructor
code :
ListAdapter adapter = new SimpleAdapter(
        getActivity(), departuresList,
          R.layout.bus_timetable_layout, new String[] { TAG_TYPE,
                TAG_HOUR }, new int[] { R.id.type, R.id.hour });

Hope this helps I have a simple application that has 3 activities. The third activity is a ListActivity that lists movie titles and their respective gross and year, choosing any movie will display the values in the first activity. The second activity is where the user can add a movie to the ListActivity by filling up EditText fields and this is where I'm having problems. , Declare this in the third Activity.
code :
public static String title, gross, year;
public static boolean newMovieAdded=false;
     ArrayList<MyMovies> movieList = new ArrayList<MyMovies>();

    if(newMovieAdded){
        MyMovies newMovie = new MyMovies();
        newMovie.setMovie(title);
        newMovie.setGross(gross);
        newMovie.setYear(year);
        movieList.add(newMovie);
        newMovieAdded = false;
}

fixed the issue. Will look into that further I have an ArrayAdapter that I would like to call (create) from a Fragment, I know how to do it from an activity but not from a fragment, perhaps one of you guys could give me the right syntax? , to create your adapter from fragment you should call:
code :
ShareHoldingAdapter adapter = new ShareHoldingAdapter(getActivity(), R.layout.listview_item_row, allShareHoldings);

Hope that helps I have a MainActivity with some fragments to run when click on side navigation menu. In the side navigation menu there is a item Called Number of SMS that shall be updated as soon as in the other fragment you choose the desired phone number. but the problem is I do not know how to refresh the list adapter from that fragment. I defined a class called allvalues which contains all my global variables. The variable responsible for SMS count is allvalues.NumberOfLocations here is the code of MainActivity: , I'd suggest to create a custom listener in your fragment like this :
code :
public interface FragmentListener {
    void refreshData();
}
private FragmentListener listener;
listener.refreshData();
public void setListener(FragmentListener listener) {
    this.listener = listener;
}
ChoosePhoneNumber fragment = new Fragment();
fragment.setListener(new FragmentListener() {
    public void refreshData() {
         //Whatever you want to do.
    }
});

this will help I have a blog app and I'm having a hard time with my PostFragment. , You can use this in your activity in order to keep the value:
code :
@Override
  protected void onSaveInstanceState(Bundle outState) {
      super.onSaveInstanceState(outState);
      outState.putSerializable("selectedFeeling", selectedFeeling);
  }
@Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        if(savedInstanceState != null){
            if(savedInstanceState.getSerializable("selectedFeeling")!=null){
            selectedFeeling = (Feeling)savedInstanceState.getSerializable("selectedFeeling");
        }
    }
}
