Changing a DialogFragment Max_Height dynamically before onResume()?

I have a custom DialogFragment which I want to change its max_height dynamically according to its view's content size (wrap content).

I don't want the update of the max_height to cause a jump in the UI so I planned to do it very early in the view's life cycle: onMeasure().

But how can I then notify the containing dialog or dialogFragment?

From Dialog fragment I can get its hosted view, but I cannot register it's onMeasure() event.

From the view I can write code in the onMeasure() method, but how will I get a reference to its containing dialog?

I saw this post, but chnging the hight at the onResume() will cause a slagish UI (jump after the UI is seen)

How about ((View) view.getParent()).invalidate() in the onMeasure() of whichever view. I realize it's sort of wrong but should fix your issue with a one liner.

Admittedly this becomes a lot more cumbersome if the recalculated-height-View is deeper in the View Heirarchy.
