title: What's the correct way to animate a View from one coordinate to another?
body: <p>I would like to do the following. I have a set of buttons that have some icons on them.  When the user taps one, I would like to introduce a new View that starts in the same coordinate as the tapped icon, and then that new View would shift over to some other location on the screen and when it arrived there be removed. </p>
  
  <p>I know how to create a new view and add/remove it to the parent RelativeLayout (should it not be a RelativeLayout?)  and all that.  What I'm not clear on is how to get the absolute coordinates of the button that was tapped (since it's just one element inside a parent layout, inside another parent layout) and then set its coordinates and apply an animation, and then what would notify me that it has arrived where it was going, so that I can remove it?</p>
  
  <p>Can't find an example of how to do this anyway, so, hoping someone can point me in the right direction. </p>
