title: YouTubeThumbnailView in ListView
body: <p>Google has released the YouTube api for Google. In that api is a YouTubeThumbnailView to display thumbnails of a movie. 
  I want to display the thumbnails in a ListView. I have made a adapter to make the views. But I'm not sure how to handle this. </p>
  
  <p>In the getView of my ListView-adapter I inflate a layout which include the YouTubeThumbnailView. According to the documentation (https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubeThumbnailView) I should call the initialize method. </p>
  
  <p>I'm wondering if I need to call the initialize method one time or also call this if the view is re-used by the ListView? There is no way to check if the YouTubeThumbnailView is already initialized? So I guess I should call it multiple times. But I have no idea if that is allowed?</p>
