how can i get the value of a color resource in my activity

Question

i need to get the string value of a color. in other words i want to pull the #ffffffff from a color resource like <color name="color">#ffffffff</color> in string format. is there any way of doing this?

Answer 1

Assuming you have:

<color name="green">#0000ff00</color>

And here is code:

int greenColor = getResources().getColor(R.color.green);
String strGreenColor = "#"+Integer.toHexString(greenColor);

Answer 2

If you need just the HEX value (without alpha):

int intColor = getResources().getColor(R.color.your_color);
String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

Answer 3

You won't be able to pull out the original source text of the XML. That is converted to a binary value at build time. (So, for instance, the difference between #fff and #ffffffff is erased.)

You can convert the color value to a hex string, of course, using Integer.toHexString(int).
