You can use simple color resources  specified usually inside   res values colors xml    use   lt color name  red  gt  ffff0000 lt  color gt    and use this via android background   color red   This color can be used anywhere else too  e g  as a text color  Reference it in XML the same way  or get it in code via   getResources   getColor R color red     You can also use any drawable resource as a background  use android background   drawable mydrawable  for this  that means 9patch drawables  normal bitmaps  shape drawables
