Answer 1

Is your getBtnClickListener method part of the ListActivity or ArrayAdapter class?

For me, when I update from the ListActivity class, I use this code...

// code to add a Contact to my database
// code to add a Contact to the list that
//   that is used by the ListView
setListAdapter(adapter);
getListView().setTextFilterEnabled(true);

When I am updating from a method inside the ArrayAdapter class, I use this code...

 // from a LongPress on a ListView item
 convertView.setOnLongClickListener(new OnLongClickListener(){
     @Override
     public boolean onLongClick(View view) {
         view.performHapticFeedback(0, View.HAPTIC_FEEDBACK_ENABLED);
         // code to remove a Contact name from my database
         // code to remove that Contact name from my list
         //    that is used by the ListView
         ContactsAdapter.this.notifyDataSetChanged();
         return true;
     });
