    Make sure you have fetched all the list items inside the doInBackground() and then updated the listview inside the onPostExecute() method.

    If you want to update the progress of fetching item and displaying item as and when it is downloaded then you have to update the listview inside the runOnUIThread()

    For example:

    /* Update UI */
myActivity.this.runOnUiThread(new Runnable() {
   @Override
   public void run() {
        /* Do UI update for activity A */;
   }
 });
