title: Android set View.GONE does not "release" space in listview
body: <p>I have a listview with some items that can be marked as "done". There is also a togglebutton that says "hide done items". </p>
  
  <p>However, when I do hide the items by setting setVisibility(View.GONE) there is still space left in the list..</p>
  
  <p>Should not be that hard to toggle list items in a listview?</p>
