I'm looking for an advanced Android color picker dialog. The standard color picker from the API Demos and examples from this post aren't quite acceptable to me. I'd like it to look like this: this image. Are there any open source color pickers that look like that?
UPDATE: My primary goal is to make the Color Picker easy to use: it'd be great if the user only needs to click once to pick any color, and all possible colors are represented. The Color Pickers from the examples I've mentioned require two clicks to pick a color and are too complicated for the average user.
