shape - How to programatically change the startColor attribute of gradient - Android

Question

I have a shape that I'm using in a layout. I want the color to be programmatically changed in my activity.

<shape android:id="@+id/shape1" xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
   <gradient android:id="@+id/gradient1"
        android:startColor="@color/widget_header"
        android:endColor="#0000CC" 
        android:angle="270"/> 

   <corners android:bottomRightRadius="1dp"
        android:bottomLeftRadius="1dp" 
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp"/> 
</shape>

Is there any way I could change the "startColor" and "endColor" attributes in my Activity?

Check this out, there's quite a bit of additional code but it seems to demonstrate how to create a drawable and gradient drawable in code... look around line 159. You may not need to create the shape in XML as you will probably need to progmatically create the shape etc
