public class utility { public static void setlistviewheightbasedonchildren(listview listview) { listadapter listadapter = listview.getadapter(); if (listadapter == null) { // pre-condition return; } int totalheight = 0; (int = 0; < listadapter.getcount(); i++) { view listitem = listadapter.getview(i, null, listview); listitem.measure(0, 0); totalheight += listitem.getmeasuredheight(); } viewgroup.layoutparams params = listview.getlayoutparams(); params.height = totalheight + (listview.getdividerheight() * (listadapter.getcount() - 1)); listview.setlayoutparams(params); } } 
put in oncreate() method:
final scrollview scrollview = ((scrollview) findviewbyid(r.id.scrollview)); scrollview.post(new runnable() { @override public void run() { scrollview.fullscroll(scrollview.focus_up); } }); the code above provides way force scroll of scrollview @ upper position. behavior can caused weight attribute in layouts etc. "debugging" of take more time apply solution above , there isn't guarantee can know each time disturbs initial scroll position.
