Android color code WHITE conversion to hexadecimal

Question

I am working with hybrid android application where i need to pass color code from java class to html. My HTML code is expecting "#RGB", where as in my android code declared some color as Color.WHITE and Color.TRANSPARENT whose equivalent int values are -1 and 0

How can i convert Color.WHITE i.e (-1) to some #FFFFFF?

I know Color.parseColor(#FFFFFF) but i need reverse one.

Since color is actually an integer, you can easily convert it to hexadecimal with String.format. It seems you want to ignore the alpha channel so you can filter it out:

String.format("#%06X", color & 0xffffff);

You could try this out

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

Reference here
