title: Android map v2 set position infoWindow
body: <p>I update my project from Android google map v1 to map v2.
  But I have a serious problem, I have to set the entire infoWindow on the screen without changing the position of the map (Only if the window can't enter in the screen).</p>
  
  <p>I make a custom InfoWindowAdapter, but how can I set the position of infoWindow ?
  Or do something to make the infoWindow center on the screen, without moving the map to center the infoWindow. </p>
  
  <p>What I want when we clic on the overlay (without moving map)

  <p>If I don't arrive to solve this probleme, I have to return to map v1 :(</p>
  
  <p>I hope, I arrive to explain my problem.</p>
