Question

I’m using Eclipse.

Problem: Code that references colors in my resource folder can’t be launched.

Example:

--><LinearLayout 

`android:background="@color/background"` // I don't have the color directory. How do I get it. (that code refers to color in my project/res folder)



  android:layout_height="fill_parent" 
</LinearLayout>

As explained by L0rdAli3n and CommonsWare, there’s no default colors file available – you have to create your own. Same as you create layout to give an example.

Here’s an example:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <!-- A COLOR NAMED background with value #FFFFFF in #RRGGBB hex value-->
  <color name="background">#FFFFFF</color>
  <!-- A COLOR NAMED mycolor with value #FFF in #RGB value-->
  <color name="mycolor">#FFF</color>
  <!-- A COLOR NAMED mycolor2 with value #00FFFFFF in #ARGB [A= ALPHA]value-->
  <color name="mycolor2">#00FFFFFF</color>
</resources>

There are currently three formats specified above which are supported. You can include this XML (without the resources tag) in Strings.xml which is in you res/values/ folder. And can straight away use them with @[:packagename]color/[colorname]

Alternatively you can create a colors.xml file in you res/values/ folder and use same as above, this is recommended and best practiced approach.
