Android :: Way To Implement A Down State On Clickable TextView?

I have a clickable TextView with a drawable as its background. I'm looking for the right way to implement a down-state drawable so the background changes when the user presses down. I have been able to almost perfectly replicate this behavior by listening for MotionEvents and changing the background when the user is pressing down.. The only thing that doesn't match up with system-wide down state behavior here is that if the user keeps holding down and moves their finger off the button, the state remains down until they release their finger from the screen... whereas in Maps overlays or Buttons or ListViews or anything else the state immediately goes back to off when the finger moves from the object.
