[android] XML shape drawable not rendering desired color

I defined a drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <solid android:color="#ffffffff" />
  <size android:width="60dp"
        android:height="40dp" />
</shape>

But how to use it in the layout definition?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              >
    <ImageView
        android:src="@drawable/ic_title"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        />
</LinearLayout>

I still see only black background.

Edited:

It turned out I missed one : in the drawable xmlns declaration. Now this example works in the Gingerbread device :)

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape>
