edit 2.0:
my activity:
public class contacts_list_activity extends activity { private searchview msearchview; private contacts_list_adapter_obj contactsadapter; private menu menu; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_contacts_list); contactsadapter = new contacts_list_adapter_obj(this); final listview listview = (listview) findviewbyid(r.id.contacts); listview.setadapter(contactsadapter); } @override public boolean oncreateoptionsmenu(final menu menu) { this.menu = menu; menuinflater inflater = getmenuinflater(); inflater.inflate(r.menu.menu_contact_list_screen, menu); msearchview = (searchview) menu.finditem(r.id.search).getactionview(); msearchview.setonquerytextlistener(new searchview.onquerytextlistener() { @override public boolean onquerytextsubmit(string s) { return false; } @override public boolean onquerytextchange(string s) { contacts_list_adapter_obj filteradapter = contactsadapter; if (textutils.isempty(s)) { filteradapter.getfilter().filter(""); } else { filteradapter.getfilter().filter(s.tolowercase()); } return true; } }); msearchview.setonsearchclicklistener(new view.onclicklistener() { @override public void onclick(view v) { set_menuitem_visible(false); } }); msearchview.setoncloselistener(new searchview.oncloselistener() { @override public boolean onclose() { set_menuitem_visible(true); return false; } }); final menuitem searchmi = menu.finditem(r.id.search); msearchview.setonquerytextfocuschangelistener(new view.onfocuschangelistener() { @override public void onfocuschange(view view, boolean querytextfocused) { if (!querytextfocused) { searchmi.collapseactionview(); } } }); return true; } }
this tried xml layout , works :
public class mainactivity extends appcompatactivity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); } the issue in case seems base activity. extend contacts_list_activity appcompatactivity
updated layout - adding app:layout_scrollflags="scroll|enteralways" toolbar , app:layout_behavior="@string/appbar_scrolling_view_behavior" listview
