Problem on android:background="@drawable/white"//

Hi,

I am brand new to the android development, please help me with the following problem if you have any idea.

I built color.xml under the rec directory,

<?xml version="1.0" encoding="UTF-8"?>
<resources>
<drawable name="darkgray">#808080FF </drawable>
<drawable name="white">#FFFFFFFF </drawable>
</resources>

however, in main.xml, the following line has error, telling that @drawable/white could not be found.

android:background="@drawable/white"

my main.xml is as follows:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/white" //this line has problem
>

Thank you.

Regards,
john

hi

you have to put the color.xml (i.e) file in the res/values/ folder (the same as the string.xml file)

the the color.xml must be formatted like this (this is rgb but you can use argb as well)

<?xml version="1.0" encoding="utf-8"?>
 
<resources>
 
<color name="red">#FF0000</color>
 
<color name="green">#00FF00</color>
 
</resources>

to use the color in a layout.xml (i.e) file
you have to do it like this
