title: number counting animation in textview
body: <p>I am developing a game application in android. I am struck at Scorecard implementation.
  I want to display score in a textview as the numbers are continously counting for movement.
  for example : suppose user crosses one obstacle and score for that obstacle is 200. Then numbers in scorecard should count from 0 to 200 smoothly and then will stop at 200.
  I have seen this type of animation in score card of papiJump. </p>
  
  <p>Please guide me.</p>
