Well I guess the talk was referring to general widgets (custom views that can be used on other views) and not appWidgets (homescreen widgets)
After spending many more hours trying to get something to work I am once again abandoning my hopes for having more information about the fully rendered size of appWidgets, its a shame, because I would like to do custom drawing in my code and it would be great it I could work with a canvas that is the same size as the end result instead of one that will eventually be scaled, thus making the clarity and precision of the image worse. So I am giving up on this hope, but I am very open to hearing any further thoughts or ideas on this subject ---snctln www.snctln.com On May 29, 9:47 pm, snctln <catlin.s...@gmail.com> wrote: > Does anyone else have any ideas on this? > > I would really like to be able to know the size of that the bitmap > from the imageView is being scaled to so that I can optimize some code > similarly to what Romain mentioned in the article I referenced in the > OP. > > Currently I read the minWidth and minHeight values from an > AppWidgetProviderInfo object, but I know that these are just the > values declared in the xml for the AppWIdgetProvider. > > So is there anyway to access a cached bitmap object after the scale > has taken place or a way to listen for the scaling event that happens > to an ImageView in an AppWidget? > > Any help would be greatly appreciated. > > ---Sean Catlin > > On May 29, 1:06 am, Romain Guy <romain...@google.com> wrote: > > > Hi, > > > A way to do this is to use the onSizeChanged() method.
