notifydatasetchanged

I'm trying to create a ListView with a list of downloading tasks. The downloading tasks are managed in a Service (DownloadService). Everytime a chunk of data is received, the task sends the progress via a Broadcast , received by the Fragment containing the ListView (SavedShowListFragment). On receiving the Broadcast message, the SavedShowListFragment updates the progress of the downloading tasks in the adapter and triggers notifyDataSetChanged() . Every row in the list contains a ProgressBar , a TextView for the title of the file being downloaded and one for the numeric value of the progress,

When I repopulate my ListView , I call a specific method from my Adapter . Problem : When I call updateReceiptsList from my Adapter , the data is refreshed, but my ListView doesn't reflect the change. Question : Why doesn't my ListView show the new data when I call notifyDataSetChanged ? Adapter : public class ReceiptListAdapter extends BaseAdapter { public List<Receipt> receiptlist; private Context context; private LayoutInflater inflater; private DateHelpers dateH; public ReceiptListAdapter(Activity activity, Context mcontext, List<Receipt> rl) { context = mcontext; receiptlist = rl;

My ListFragment code public class ItemFragment extends ListFragment { private DatabaseHandler dbHelper; private static final String TITLE = "Items"; private static final String LOG_TAG = "debugger"; private ItemAdapter adapter; private List<Item> items; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.item_fragment_list, container, false); return view; } @Override public void onCreate(Bundle savedInstanceState) { super.setHasOptionsMenu(true); super.onCreate(savedInstanceState); getActivity()
