Android buttons use same Drawable for shape but use different colors

In my application I am using lot of buttons. And all buttons must be in same shape but different in color. I wrote drawable for each button with same features but different solid android:color. This makes more than 20 drawable xml in my app. How can I use the same drawable for all buttons, but should be able to set different background color. I tried as below, but did not work.
1. In attrs.xml

  1. In drawable folder created buttonshape.xml for rectangle shape


  2. In styles.xml @drawable/buttonshape
    @color/mycolor

  3. In Colors.xml #000000

And finally in my activity xml, for the button I set the theme as 

<Button android:id="@+id/btnTest" 
android:theme="@style/TestTheme"   android:text="Test" />

This did not work for me. Could anyone of you please help me to sort this out? I am a new to android development. I am not able to figure out where I am going wrong. Any help would be really appreciated. Thanks, Roger

use this: GradientDrawable bgShape = (GradientDrawable)view.getBackground().getCurrent(); bgShape.setColor(Color.BLACK);

where ever you want to set different color of any view, just use this code.

.getCurrent gives the selected drawable layerlist

use this it will not throw java.lang.ClassCastException: android.graphics.drawable.GradientDrawable cannot be cast to android.graphics.drawable.ShapeDrawable exception.

it works perfectly for me.
