title: Swipe gesture for number input
body: <p>If (in Android) you wanted to write an alarm app where the user entered in the time for the alarm by swiping the hours &amp; minutes up and down, what's the easiest way of achieving this? Is it the Swipe or Fling command? </p>
  
  <p>Are there any good tutorials out there for this?</p>
  
  <p>Cheers</p>
