The photo cannot extract black.

[chengkaizone]

I plan to extract the color of an album image and it works fine, but the black part never returns the correct color value Set the picture code as follows: val bitmap = BitmapFactory.decodeFile(path) if (bitmap != null) { val drawable: Drawable = BitmapDrawable(resources, bitmap) colorPickerView.setPaletteDrawable(drawable) }
