solution

i change second scrollview 1 horizontalscrollview , work!!!

very bad programming practice. can't embed scrollview inside scrollview.

in general listview inside scrollview not working because listview has own scrolling functionality , again embedding scrollview class thats why create jerk.

same in how should integrate scrollview inside scrollview? think logically how should possible? confuse scrollview getting triggered?
