title: Toggle checkbox programmatically
body: <p>I have a ListView of items that need to be checkable/uncheckable.  I have set up an ArrayAdapter that is currently using android.R.layout.simple_list_item_multiple_choice as the row, and everything displays just fine.  I am also able to properly get the clicks on this item.  However, the Checkbox in the UI <em>does not toggle</em> when the item is selected.  I've been trying to figure this out for a while, can anyone point me in the right direction?  I just want to know how to force the UI to update to reflect the changed state of the checkbox.</p>
  
  <p>I can provide code if needed, but I'm trying to look for something very specific here, so I figure posting a bunch of my code wouldn't be of much help.</p>
  
  <p>Thanks!</p>
