Change ARGB color int's single channel value

Question

If I have a color:

int color = 0x1a2cf3bb; // just an example

How can I change, for examle, just the R channel with the value:

int red = 0xfe; // another example

So that color becomes:

color = 0x1afef3bb;

color = (color & 0xFF00FFFF) | 0x00FE0000. – harism Mar 17 '13 at 16:12 — harism, Mar 17 '13 at 16:12
