Answer 1

You could also use the [red, green, blue] function of the Color class:

    int color = getResources().getColor(R.color.youcolor);
    int r = Color.red(color);
    int g = Color.green(color);
    int b = Color.blue(color);

Answer 2

Edit: This was accepted as the answer but have a look at @johann's answer too, it will leave you and those reading your code less confused.

If you want to learn about the underlying representation of colours, you could start here.

Original answer:

getColor() gives you the colour as an ARGB int.

int color = getResources().getColor(R.color.ItemColor1);
float red   = (color >> 16) & 0xFF;
float green = (color >> 8)  & 0xFF;
float blue  = (color)       & 0xFF;
float alpha = (color >> 24) & 0xFF;

Answer 3

Please take a look

How to get RGB value from hexadecimal color code in java

int color = Integer.parseInt(myColorString, 16);
int r = (color >> 16) & 0xFF;
int g = (color >> 8) & 0xFF;
int b = (color >> 0) & 0xFF;

Answer 4

Updated with ContextCompat as getColor is Deprecated.

int color = ContextCompat.getColor(mContext, R.color.colorAccent);
float red = (color >> 16) & 0xFF;
float green = (color >> 8) & 0xFF;
float blue = (color) & 0xFF;
float alpha = (color >> 24) & 0xFF;

Hope it will useful.
