title: Shared Element list changes
body: <p>Activity A contains a list of images. Activity B contains the selected image. Using shared elements it successfully animates the image being moved to the new activity and back again when I finish B. </p>
  
  <p>The problem is when the list is changed and I am on B, the image will try to go back to the same spot in the list. If it was the 10th item in the list when I selected it, then when I press back there are only 3 images in the list now it will throw an exception as that 10th list item container won't exist anymore. If I select the 1st list image, but whilst on B the list grows and my item is forced to the 5th spot in the list, when I press back it will still go back to that 1st list item it came from.</p>
  
  <p>Is there a way I can tell it to move to a different list item on its return transition? (Activity B is informed when the list changes, so I do have the option to get it's new position)</p>
  
  <p>Any suggestions would be great guys.
  Thanks</p>
