title: Invisible / transparent button that works like a regular in android?
body: <p>How do I get one area in the middle of a image clickable (not the whole image)? Tried with a button set to invisible and clickable but the button does not work. What are the alternatives to an invisible / transparent button that works like a regular?</p>
  
  <p>I've also thought of a completely transparent and clickable PNG that should work but maybe not the best way?</p>
