NumberPicker on ScrollView doesn't scroll on Android 4.0.4 -

i trying use number picker on activity parent scrollview. since there 2 number pickers arranged vertically. number picker doesn't scroll on android 4.0.4; though works on android 4.1.2

i tried remove 1 number picker, scroll view hides itself, see behavior. still seeing same. numberpicker doesn't change values , stuck. though , down arrows work well, in both cases.

without scrollview in place, works well.

please help.

i know old question, still...

this works me:

numberpicker.setontouchlistener(new ontouchlistener() {      @override     public boolean ontouch(final view v, final motionevent event) {         if (event.getaction() == motionevent.action_move && v.getparent() != null) {             v.getparent().requestdisallowintercepttouchevent(true);         }         if (event.getaction() == motionevent.action_up) {             v.performclick();         }          v.ontouchevent(event);         return true;     } });
