As I still can not comment, I will answer this as an answer, although now it can solve your problem.

I had the same problem when displaying images in a list that were loaded in an asynchronous stream, and this happened when I clicked on an element (and thereby open another action) and immediately clicked on the back button, returning to ListActivity.

So, I decided (apparently) to solve the problem in order to hide the list, stopping the action and displaying the list again, returning to it.

 @Override protected void onStop() { super.onStop(); getListView().setVisibility(View.GONE); } @Override protected void onRestart() { super.onRestart(); getListView().setVisibility(View.VISIBLE); }

Pretty simple, huh?

Hope this helps you.
