Description Jérémie Laval 2014-03-28 22:43:14 UTC

The documentation read as left/top for a negative integer value and right/bottom for a positive one. We bind this to FocusSearchDirection which has no equivalent meaning.

I have checked this issues and I am able to reproduce this issue.

I have check this issue on "Assembly browser" and I observed that in android documentation  "canScrollVertically()" and "canScrollHorizontally()" takes integer type input parameter and read as left/top for negative integer and right bottom for positive one, but in xamarin, I observed that for "canScrollVertically()" and "canScrollHorizontally()" methods takes "Enum" type input parameter i.e.  "FocusSearchDirection".

I have also observed that the values of  "FocusSearchDirection" enum is not negative integer. It is positive integer. Values of "FocusSearchDirection" enum are:
                Backward = 1,
		Down = 130,
		Forward = 2,
		Left = 17,
		Right = 66,
		Up = 33
