android - Create a scrollable LinearLayout without a ScrollView -

i spent part of day looking scrolling content in android. however, in app need apply custom type of scrolling contains among other things listview. listview has own scrolling , scrollview should never used list view together.

but there must intrinsic scroll functionality views. documentation on view indicate support methods provided not seem provide listeners detect scrolling.

a scrollview built on framelayout problematic in app.

you can make linearlayout scrollable with:

android:isscrollcontainer="true" 

but doesn't seem anything.

in fact can set scrollbars linearlayout:

android:scrollbars="vertical" 

but doesn't seem anything.

i don't want control scrolling rather have listener detects scrolling on screen regardless whether listview, framelayout or other control visible. guess looking writing own custom scrollview control without limitations of framelayout , unnecessary overhead don't need. suggestions?

on way resolve above problem have 2 scrollview, 1 outer scrollview contain view , other inner scrollview instead of listview , adding items inside linearlayout dynamically(inside inner scrollview)
