ANDROID：Color和Hue的等效混合模式（porter duff）是什么

Question

I'm trying to create an effect that I saw in an IOS application where the they used a blend mode of color and one of hue, but I couldn't find those blend modes in the PorterDuff.modes enum. Do you know if there are equivalent modes in android? Thanks!

Answer 1

It depends exactly what you're trying to do; depending on the color used, you could use PorterDuff.Mode.MULTIPLY or SRC_OVER ; hue is a little more complex.

If none of the modes suit your needs (because, no, there are no default color/hue PorterDuff modes), this answer may tickle your fancy. It's basically adjusting the hue of a ColorMatrix , which can then be applied to a Drawable . (That process is elaborated on in the preceding answer's OP.)
