Changing a DialogFragment Max_Height dynamically before onResume()?

Question

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)

yes, i want to set the max_height according to the dialog content — Elad Benda, Apr 26 '19 at 18:44
Then maybe extending `DialogFragment` is a better option. By this you'd inflate your own layout that extends with content. — Onik, Apr 26 '19 at 18:55
I do extend but I want to change the max_Height according to the measure of the dialog content. How will you do it with avoiding UI jump? — Elad Benda, Apr 27 '19 at 17:30
At what point do you want to change the height of your DialogFragment? — serg3z, Apr 28 '19 at 14:27
@serg3z I want to change its max_height dynamically according to its view's content size (wrap content) at the earliest point (avoid slagish UI) — Elad Benda, Apr 28 '19 at 14:44
@EladBenda you know content height when called onCreateView? — serg3z, Apr 28 '19 at 17:05
I did it in `onCreateDialog()` to resize width and there is no glitch. Have you tried? — underoid, May 01 '19 at 21:33

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.
