Android Gradient drawable color change

Question

I have a shape drawable in the drawable folder. Here is XML structure:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <gradient 
        android:startColor="#4D0418" 
        android:centerColor="#5F031D"
        android:endColor="#7D0227" 
        android:angle="-90" />
</shape>

Now I want to change the startColor, centerColor, endColor from the java code in the runtime. How it is possible to change?

You should be able to do it using Java reflection.

Unfortunately there's no API to do this. I'll add one to a future Android release.

Is there anyway to recreate the total drawable through java code without using any XML?

I have created a GradientDrawable which is substitute of <gradient></gradient>. But how can I set it to any shape? Should I use ShapeDrawable for that? if it is, then how I can set my GradientDrawable to that ShapeDrawable?

GradientDrawable is a substitute for both <shape/> and <gradient/>

GradientDrawable doesn't appear to have anything equivalent to the ShapeDrawable's setShaderFactory method, which can be used to create a gradient with more than just 3 colors. Hmm. :-/

This appears to be in API 16.
