Android string.xml颜色

Question

Color specified as

<font fgcolor="#ffff0000">red</font>

works, while

<font fgcolor="#0000FF">blue</font>

does not work.

How fix this problem?

Answer 1

On Android color is defined as ARGB where A stands for alpha channel (transparency). For alpha, value of 00 means fully transparent, and FF means fully opaque. So when you define your color as RGB , ommiting A part, then A is being considered as set to 00 which in result makes your color fully transparent, thus your color is invisible and may look like not working . This behaviour sometimes can differ and lack of of A can be interpreted as opaque, but this is rather exception so it's safer to always specify alpha value. BTW: color cannot work anyway :)
