How do i check the length for Color.red(c) in android?

Question

As for the RGB value maximum value for each can be 255(length is 3) but for each color. For eg : if Color.red(c) gives the value 12(length is 2) for red then i want to add 0 in front and make it 012 how can i do that. It was possible if i could check the length but i do not know how to do it.

Answer 1

To check the length you can try something like

int red = Color.red(c);
if (red < 10) {
    //0...9 
} else if (red < 100) {
    //10..99
} else {
    //100..255
}

In the each if you can add to the value as many zeros as you want.

Answer 2

String colorLeadingZeroes = String.format("%03d", Color.red(c));

this will force the result to be a string of three digits with leading zeros replacing the spaces
