Question

I have a hexidecimal number (a color) stored in a String as followed: “ff62e6b8”.
I need to convert this back to an integer so I can use it as a color value again.
I have tried the following:

Int i = Integer.parseInt("ff62e6b8", 16);
Int i = Integer.valueOf("ff62e6b8", 16);
Int i = Integer.decode("ff62e6b8");

But all of these methods raise exceptions. Am I missing something here?

Answer 1

Try with this :

int colorVal = Color.parseColor("#ff62e6b8");

Example :

myLayout.setBackgroundColor(Color.parseColor("#ff62e6b8"));

By this you will get colorVal = -10295624.

And if you want to generate hexColor code back from the colorVal then use this :

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

By this you will get hexColor = #62E6B8.

Thanks.
