Description

Description

I need to display some controls on an Image. So, I need to put image inside RelativeLayout or AbsoluteLayout. But both of these layouts expand beyond the Image. This causes wastage of space. RelativeLayout is taking even more space than AbsoluteLayout. These Layout should adapt according to the size of its children. Exactly as StackLayout.

Steps to Reproduce

Swap RelativeLayout and AbsoluteLayout in my repro project.

Basic Information

  • Version with issue: Xamarin.Forms-pre10
  • IDE:Visual Studio for Mac
  • Affected Devices:iOS and Android.

Research direction
Reproduce the issue with a minimal Xamarin.Forms project. Examine how AbsoluteLayout and RelativeLayout measure and arrange their children. Compare with StackLayout's layout pass. Check if the issue is related to the layout's default size or constraints. Look at Xamarin.Forms source code for layout logic.
