How to Convert #RGBto #RRGGBB

Question

I have to convert a color string in the format #RGB to #RRGGBB like #0af To #RRGGBB now can any one help out here using android

This requires basic programming skills in Java, nothing else. If you don't have them, think twice about whether or not to proceed from here. — class stacker, Apr 30 '13 at 07:32

One way is:

String rgb = "#0AF";
String rrggbb = "#";
for (int i = 1; i < rgb.length(); i++) {
    rrggbb += (rgb.charAt(i) + "" + rgb.charAt(i));
}

int newRgb = 17 * (((oldRgb & 0xF00) << 8) | ((oldRgb & 0xF0) << 4) | (oldRgb & 0xF));

oldRgb is supposed to be int as well as newRgb – Dmitry Bychenko Apr 30 '13 at 07:39

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

thats what i was searching. It will ensure that color string always will be #RRGGBB.

Oh really? I think it's obvious that this doesn't do what you asked for. – class stacker Apr 30 '13 at 08:38
@ClassStacker thanks for ur suggestions but i dont think u r a right person to tell me what i asked is wrong or right ...ok ...enjoy . \m/ – GOLDEE Apr 30 '13 at 12:06
Oh, am I not? That surprises me. Because Daryn and @Dmitry Bychenko spent their time on answers which are based on an interpretation of your question which matches mine. I'd call that a majority. But I presume you're just after as much free code as possible. And you're very young, that explains a lot. Farewell, my friend! – class stacker Apr 30 '13 at 12:22
