Description

On Android, the ScrollableView scroll event is actually fired when dragging stops; it should therefore be renamed to dragEnd. Then, a proper scroll event, fired continuously as the view is scrolled, is needed. These changes have been addressed in my pull request: [titanium_mobile/#2101](https://github.com/appcelerator/titanium_mobile/pull/2101#issuecomment-5480208)

Test case from Russ's PR

With a little addition to make it viable as an app.js.

   var win = Ti.UI.createWindow({backgroundColor: "#444"});
   var view1 = Ti.UI.createView({ backgroundColor:'#123', width: 250 });
   var view2 = Ti.UI.createView({ backgroundColor:'#246', width: 250 });
   var view3 = Ti.UI.createView({ backgroundColor:'#48b', width: 250 });
   
   var scrollableView = Ti.UI.createScrollableView({
     views: [view1,view2,view3],
     showPagingControl: true,
     width: 260,
     height: 430
   });
   
   win.add(scrollableView);
   win.open();
   
   scrollableView.addEventListener('scroll', function (e) {
      Ti.API.debug('scrollableView got a scroll event: float:' + e.currentPageAsFloat +  ' int: ' + e.currentPage);
   });
   
   scrollableView.addEventListener('dragEnd', function (e) {
      Ti.API.debug('scrollableView got a dragEnd event: ' + e.currentPage);
   });
   
   scrollableView.addEventListener('scrollEnd', function (e) {
      Ti.API.debug('scrollableView got a scrollEnd event: ' + e.currentPage);
   });

Run that and watch logcat, make sure the values shown in logcat are logical.
