从Android Color对象获取红色，蓝色或绿色通道

Question

I feel this is a pretty stupid question, but the Android Color class doesn't seem to have a method to get an int from the R, G, B channels from a Color object individually. Can I get the channels somehow like java.awt's Color can?

Answer 1

int color = ContextCompat.getColor(context, R.color.someColor);
        int red = Color.red(color);
        int blue = Color.blue(color);
        int green = Color.green(color);
        int alpha = Color.alpha(color);

Answer 2

Did you mean

int colorValue=Color.parseColor(#121212);
int red=Color.red(colorValue);
int green=Color.green(colorValue);
int blue=Color.blue(colorValue);

Answer 3

try this:

String myPassedColor = "#ffffff";
int color = Color.parseColor(myPassedColor)
int r = Color.red(color);
int g = Color.green(color);
int b = Color.blue(color);
int a = Color.alpha(color);
