Usage example:
B4X:
Dim gd As GradientMaker
gd.Initialize
gd.SetGradient(View, "TOP_BOTTOM", Array(XUI.Colors_Red, 0xFF00FF00)) 'same orientations as GradientDrawable. Supports any number of colors.See the attached example.
BTW, the example uses the nice DDDGrid class: https://www.b4x.com/android/forum/threads/b4x-dse-dddgrid-designer-script-grid.142402/#content
