The answer of st0le is not correct with respect to colors. It does not work if first color components are 0. So toHexString is useless.

However this code will work as expected:

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

Your absolutely right. I don't understand why the others downvoted your answer. Thank you anyway! – DragonWork Oct 28 '12 at 16:52
I got a different answer. My R=71, G=159, and B=83 the Hex it's displaying is `6C94C` but it really is `479f53` – Si8 Aug 31 '13 at 19:07

Warning: this 6 digits version would not work with 8 digits hexa colors if using alpha channel. – John Sep 20 '15 at 13:55

For the 8 digits color: String.format("#%06X", 0xFFFFFFFF & intColor); – Ayaz Alifov Jan 17 '18 at 11:54

FYI: this answer doesn't support alpha channel. – Saket Feb 04 '18 at 06:15

Here are 2 ways to convert Integer to Hex Strings...

    int  n = 123456;
    System.out.println(String.format("#%X", n)); //use lower case x for lowercase hex
    System.out.println("#"+Integer.toHexString(n));

If you want to convert to javascript format:

val hexColor = String.format("%06X", 0xFFFFFFFF.and(R.color.text.toColorInt(context).toLong()))

val javascriptHexColor = "#" + hexColor.substring(2) + hexColor.substring(0, 2)

Use this way

Java:

 String hexColor = "#" + Integer.toHexString(ContextCompat.getColor(context, R.color.colorTest))

Kotlin:

var hexColor = "#${Integer.toHexString(ContextCompat.getColor(context, R.color.colorTest))}"
