Hi I cant seem to get a listview working in my tab layout. It keeps failing at list.setAdapter(mSchedule); This is my code and XML. Thanks for any input

   public class ttTuesday extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ListView list = (ListView) findViewById(R.id.LISTVIEW);
    ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
    HashMap<String, String> map = new HashMap<String, String>();

    for(int i=0; i<About.timetable.length; i++){

        //check if sorting by category and make sure at least one category is TRUE
        if(About.timetable[i][0].contains("Tuesday")){

                map = new HashMap<String, String>();
                map.put("time", About.timetable[i][1] + "-" + About.timetable[i][2]);
                map.put("location", "\tLocation: " + About.timetable[i][4]);
                map.put("subject","\tSubject: " +  About.timetable[i][3]);
                mylist.add(map);


        }
}
    final SimpleAdapter mSchedule = new SimpleAdapter(this, mylist, R.layout.timetableday,
            new String[] {"time", "location", "subject"}, new int[] {R.id.TIME, R.id.LOCATION, R.id.SUBJECT});
    list.setAdapter(mSchedule);
    list.setTextFilterEnabled(true);

}

You didn't put the ListView in a tab. Just because it is a child of the FrameLayout does not automatically set up a tab for it. Here is a sample project demonstrating how to take children of a FrameLayout and add them as tabs to the TabHost.
