below code:
activity class:
public class orderactivity extends fragmentactivity implements onorderselectedlistener { private static final string tag = "orderactivity"; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); log.d(tag, "oncreate called"); setcontentview(r.layout.order_details); if (findviewbyid(r.id.fragment_container) != null) { if (savedinstancestate != null) { return; } orderlistfragment orderlistfragment = new orderlistfragment(); orderlistfragment.setarguments(getintent().getextras()); getsupportfragmentmanager().begintransaction() .add(r.id.fragment_container, orderlistfragment).commit(); } } @override public void onorderselected(int position) { log.d(tag, "onorderselected called"); orderdetailfragment detailsfrag = (orderdetailfragment) getsupportfragmentmanager() .findfragmentbyid(r.id.order_detail_fragment); if (detailsfrag != null) { if (!detailsfrag.isvisible()) { detailsfrag.setuservisiblehint(true); detailsfrag.updateorderview(position); } } else { orderdetailfragment newfragment = new orderdetailfragment(); bundle args = new bundle(); args.putint(orderdetailfragment.arg_position, position); newfragment.setarguments(args);; fragmenttransaction transaction = getsupportfragmentmanager() .begintransaction(); transaction.replace(r.id.fragment_container, newfragment); transaction.addtobackstack(null); transaction.commit(); } } } list fragment

try this
listview.setchoicemode(listview.choice_mode_single); listview.setitemchecked(0,false);
