API

styleables

ArcScrollView
    radius: dimension = defines the radius of the drawn circle
    stroke_width: dimension = defines how much of the circle should be visible
    findBestWidth: boolean = let the ArcScrollView decide the width

ArcLinearLayout
    useMinPadding: boolean = add an extra padding to top and bottom of items if set to true won't add any extra padding
    itemsOffset: dimension = how much the items in ArcLinearLayout should be offset from top of the arc

What need to be implemented?

Currently it doesn't support screen rotation. if this feature is asked for i will work on it.
