how to set different color of border of rectangle using stroke

How about, if just to get top border or left 开发者_如何转开发border using stroke. Is it possible to set different width for different borders

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
 <solid android:color="#FAFAFA"/>
 <stroke android:width="1px" android:color="#cccccc" />
 <corners android:bottomRightRadius="10dp" android:bottomLeftRadius="10dp" 
     android:topLeftRadius="0dp" android:topRightRadius="0dp"
/>

</shape>

Hope you can see the xml i am using. Thanks
