How to attach OnScrollListener to a ListView

[ales]

Hi,
I am trying to use Macroid to attach OnScrollListener to a ListView:

w[ListView] <~ FuncOn.scroll[ListView] {
   (view: AdapterView[_], first: Int, visCount: Int, totalCount: Int) =>
      println("doing something")
}

but of course this causes this error message to be thrown on compile time:

object creation impossible, since method onScrollStateChanged in trait OnScrollListener of type (x$1: android.widget.AbsListView, x$2: Int)Unit is not defined.

It there a macroid technique to avoid this message (e.g. define empty onScrollStateChanged method)?

Thank you for any hint

Actually I did the following, but little bit more verbose solution:

w[ListView] <~ Tweak[ListView] { l =>
   l.setOnScrollListener(new OnScrollListener {
      override def onScroll( absListView: AbsListView, first: Int, visCount: Int, totalCount: Int ): Unit = {
         println(s"Scroll: $first, $visCount, $totalCount")
      }
      override def onScrollStateChanged( absListView: AbsListView, i: Int ): Unit = {
         println(s"ScrollStateChanged: $i")
      }
   })
