If you need a cross platform solution then use BitmapCreator to create the gradient and draw it with Canvas.DrawBitmap.

If it is a B4A only solution then you can get the original Canvas and use DrawDrawable: https://www.b4x.com/android/forum/threads/b4xcanvas-getcanvas.98799/post-622296

See Klaus example: https://www.b4x.com/android/forum/threads/gradients-and-circles-ovals.105636/post-661566
And my following examples as well.

Note that you should reuse the BitmapCreator when possible.

You find an example of drawing a round corner rectangle with four gradient colors in the B4X Graphics booklet.
