    well, I guess the title says it all...

    How can I get a views corner radius?

    and while I'm at it, how to get the border thickness?

    Sorry pal no ideas this time, but if you are setting the view in the first place then maybe you can store the values that were used to create the view to use later as required? Just an idea if it's a view that is created in code?

    Assign an id (with tag) to the view, create a map an store the view Id as a key and the corner radius as value.

    After that is just imagination with map.get(view.tag)

    You can use this code to get these values for views with ColorDrawable background.
    Code:
    If GetType(Label1.Background) = "anywheresoftware.b4a.objects.drawable.ColorDrawable$GradientDrawableWithCorners" Then
           Dim cd As ColorDrawable = Label1.Background
           Dim jo As JavaObject = cd
           Log($"Radius = ${jo.GetField("cornerRadius")}, BorderWidth = ${jo.GetField("borderWidth")}"$)
    End If

    Thanks Erel!

    One question, why do you need to check the view type?

    We are checking the view's background type. It can be a different type if for example you use GradientDrawable in the designer.

    It is more difficult to get the background color due to the way it is saved. Will be easier to use the Tag property for this.

    I'm using bitmap and canvas to get the background color as suggested in another thread. Thanks Erel
