title: Change shape and color of ToggleButton(or maybe somthing else)?
body: <p>I want a togglebutton that looks like a fire or spark. I want to indicate when the button is selected and when its not.
  As far as I know this can be done using a Selector-drawable. Now I want to change color of the "fire" on my button from code. And I want the color to be changed in both the selected and the unselected drawable. </p>
  
  <p>How can I achieve this?</p>
