title: Animate two views like when you pass a phone call
body: <p>I have made many tries to have the same effect of switch than the one you can see when calling a phone number : the front view disapear with a zoom effect, while the other one appears also with a zoom effect.</p>
  
  <p>I can't achieve doing that effect, it's always a so-so. There seems to have a scale effect, with an action on opacity, but...</p>
  
  <p>Do you know how this can be done to reflect that effect (not a so-so, I have tons of those) ? </p>
