is there any api for doing the same in Andorid

Answer 1

You can use the Color class which is an default android class.

int rgb = Color.rgb(red, blue, green)

it has static method rgb() which takes the red, blue and green colors and returns the mixed color.

Answer 2

I would use this small snip it:

int r = (color >> 16) & 0xFF;
int g = (color >> 8)  & 0xFF;
int b =  color        & 0xFF;

This takes your color and converts it to the channels. The >> operator does bit shifting which is equal to a division of 256 or 65536. That is by the way the same thing what the android.graphics.Color class does internally.

Answer 3

You can use the android.graphics.Color class. It has a red(int), green(int) and blue(int) method (among some others useful methods).
