title: Multiple Functions in a Single Button
body: <p>I have a google map project, and I am wondering how I would be able to change to different map types using a single button click.</p>
  
  <p>For Example:
  At the first time run of app, the map type is NORMAL, then when I tap on the button it will change to TERRAIN, then when I tap on the button again it will change to HYBRID, and when I tap on the button again it will change to NORMAL. </p>
  
  <p>It seems kinda easy when you think about it, but I don't know how will I approach it, how would it be done? Thanks in advance for the help! :D</p>
