Android Question DrawRect and Colors.Transparent incorrect

[kiki78]

I have problem with DrawRect with Colors.Transparent.
Any transparent color construct with Colors.ARGB(A, R, G, B) with A = 0 and any of R, G or B <> 0 work fine, but with all 0 it draw black.

Best Regards,

When you call DrawRect with Colors.Transparent (all 0) then it creates a "hole" in the canvas. This allows you to erase parts of the canvas and show the background.

Ok, so this is not a bug but a "by design".
So when I doesn't want this, I just need to test value before draw.

Thank you Erel.
