Scroll event of big-size items within Android ListView
<p>I have a ListView containing big-sized items. Each item may occupy more than one screen. 
My objective is to calculate the offset (view.getTop()) of the first visible item on the screen. </p>

<p>I use setOnScrollListener to capture the scrolling event. The problem is that the onScroll event is only triggered when the visible item changed. If one item vertically spanned bigger than the screen size, then the onScroll event is not triggered during the scrolling of this big item.</p>

<p>Is there any other event that I could capture to achieve my objective?</p>

<p>Thanks</p>
