Anchor contents to bottom about contour HOT 4 OPEN

Temporarily achieved this by wrapping MyContourView inside a ConstraintLayout in my fragment. The ConstraintLayout has a dummy View at the top (a "spacer") that expands to fill the space available to it. Not very satisfied though.. hoping there is a way without nesting ViewGroups like this.

I am currently trying to achieve the same and I plan to do it like this:

Let's say my view is split into 2 parts: Main and AnchoredToBottom. If there is no space, than A follows immediately below M, otherwise spacing is added so that A appears to be anchored to the bottom

1. In contourHeightOf: if bottom() - A.height() < M.bottom() then we have an overflow and return A.bottom() else we return it unmodified
2. In A.applyLayout() we also check for overflow and either do A.topTo { M.bottom() } if there is an overflow or do A.topTo { M.bottom() - calculateTopMarginBasedOn(parent.height()) }

What I currently miss here is comparison operators for YInt/XInt, actually I came to file an issue and noticed your report :)

Oops, this won't work because there's no way to know bottom() of whole contour layout in contourHeightOf { }...

from contour.

The problem with the original layout is MyContourLayout has a height that is a function of view2.bottom() and view2.bottom() is a function of MyContourLayout's height.

It's not satisfying but the solution here would be:

contourHeightOf { availableHeight ->
  maxOf(availableHeight, view1.height() + view2.height() + interItemMarginPx)
}
