title: How to make a gradent constant-glow with gradient shadow button in android?
body: <p>I know this topic has been discussed before but I didn't find really what I am looking for.</p>
  
  <p>I have those buttons (screenshot at the bottom). Now I want to add a constant outer glow. Is there another possibility to do this than saving it as .png in the drawable folder? That would make much less work.
  Thank you!</p>
