title: Android long-touch event
body: <p>I have two buttons that increment and decrement a value by one with each press and they're working just fine with the onClickListener. I see that an onLongClickListener exists, which I assume is for touch and hold events. How would I have the number rapidly increment/decrement if the button is held?</p>
  
  <p>Am I correct in assuming that onLongClickListener only fires once per long click? Is there a more appropriate listener or a property somewhere that I'm not aware of?</p>
