Romain, Thank you very much for the quick response I really appreciate it.
This sounds like a very reasonable approach to this problem, but unfortunately I am still confused. I apologize in advance, because I am sure this is a simple concept that I am just not understanding at the moment... Before I go any further I figure I should explain my basic widget update procedure I do it all in a service at the recommendation of jsharkey to avoid ANR dialogs, my service runs somewhat like this - grab an instance of the appWidgetManager - get all of the appWidgetIds for my widget - start loop over these ids -- create a new RemoteView object from the widget Id and my xml Layout which is just a frameLayout and an ImageView -- set the imageView bitmap via RemoteViews.SetImageViewBitmap() -- update the widget via appWidgetManager.updateAppWidget - end loop So usually when I want to get ahold of a view I do a findViewById in an activity, but since I am doing this from a service I didn't think I had access to this method. Where do I access the actual ImageVIew being used so that I can get access to the onSizeChanged method? Or am I thinking about this all wrong? Thanks again for the quick response, I am looking forward to anything else you can help me with on this matter. ---snctln - end loop So I can use teh onSizeChanged() method to see when the bitmap gets scaled... I assume this is for the image View? On May 29, 1:06 am, Romain Guy <romain...@google.com> wrote: > Hi, > > A way to do this is to use the onSizeChanged() method.
