With this method Integer toHexString  you can have an Unknown color exception for some colors when using Color parseColor   And with this method String format    06X    0xFFFFFF  amp  intColor    you ll lose alpha value   So I recommend this method   public static String ColorToHex int color            int alpha   android graphics Color alpha color           int blue   android graphics Color blue color           int green   android graphics Color green color           int red   android graphics Color red color            String alphaHex   To00Hex alpha           String blueHex   To00Hex blue           String greenHex   To00Hex green           String redHex   To00Hex red               hexBinary value  aabbggrr         StringBuilder str   new StringBuilder               str append alphaHex           str append blueHex           str append greenHex           str append redHex             return str toString               private static String To00Hex int value            String hex    00  concat Integer toHexString value            return hex substring hex length  -2  hex length

If you use Integer toHexString you will end-up with missed zeros when you convert colors like 0xFF000123  Here is my kotlin based solution which doesn t require neither android specific classes nor java  So you could use it in multiplatform project as well        fun Int toRgbString    String               red toStringComponent     green toStringComponent     blue toStringComponent     toUpperCase        fun Int toArgbString    String               alpha toStringComponent     red toStringComponent     green toStringComponent     blue toStringComponent     toUpperCase        private fun Int toStringComponent    String           this toString 16  let   if  it length    1   0  it   else it        inline val Int alpha  Int         get      this shr 24  and 0xFF      inline val Int red  Int         get      this shr 16  and 0xFF      inline val Int green  Int         get      this shr 8  and 0xFF      inline val Int blue  Int         get     this and 0xFF
