title: how to detect Android ListView Scrolling stopped?
body: <p>I'm trying to do something after scrolling stopped.So, I tried using <code>OnScrollListener#onScrollStateChanged(SCROLL_STATE_IDLE)</code> to detect when the scrolling stopped(either <code>TOUCH_SCROLL or FLING</code>)(at 1.5 it's runs as i expect).
  But when it runs on 2.0, onScrollStateChanged can't received the event after releasing the finger.Is there any callback or anyway to detect that event? </p>
