Google Maps API v2 SupportMapFragment inside ScrollView - users cannot scroll the map vertically

Question

I am trying to put a Google map inside a scroll view, so that the user can scroll down other contents to see the map. The problem is that this scroll view is eating up all t

Thank you for suggestions,

After much try-and-error, pulling off my hairs and swearing at monitor and my poor Android test phone, I've figured that if I customise ScrollView, override onInterceptTouchEvent in which we return false when the event is on a map view no matter what, then the scrolling on a map does happen as expected.

class MyScrollView(c:Context, a:AttributeSet) extends ScrollView(c,a) {
  val parent = c.asInstanceOf[MyActivity]
  override def onInterceptTouchEvent(ev:MotionEvent):Boolean = {
    var bound:Rect = new Rect()
    parent.mMap.getHitRect(bound)
    if(bound.contains(ev.getX.toInt,ev.getY.toInt))
      false
    else
      super.onInterceptTouchEvent(ev)
  }
}

This code is in Scala but you get the idea.

Note I've ended up using a raw map view (as shown in android-sdks\extras\google\google_play_services\samples\maps\src\com\example\mapdemoRawMapViewDemoActivity.java). Guess you can do the pretty much same thing with fragments, I just never liked fragments in the first place.

I think Google owes me an apology.
