i have navigation drawer image. want add section separator (like line separating neptune). seems simple can't find on web useful case.
here mainactivity:
public class mainactivity extends activity { private drawerlayout mdrawerlayout; private listview mdrawerlist; private actionbardrawertoggle mdrawertoggle; private charsequence mdrawertitle; private charsequence mtitle; private string[] mplanettitles; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); mtitle = mdrawertitle = gettitle(); mplanettitles = getresources().getstringarray(r.array.planets_array); mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout); mdrawerlist = (listview) findviewbyid(r.id.left_drawer); // set custom shadow overlays main content when drawer opens mdrawerlayout.setdrawershadow(r.drawable.drawer_shadow, gravitycompat.start); // set drawer's list view items , click listener mdrawerlist.setadapter(new arrayadapter<string>(this, r.layout.drawer_list_item, mplanettitles)); mdrawerlist.setonitemclicklistener(new draweritemclicklistener()); // enable actionbar app icon behave action toggle nav drawer getactionbar().setdisplayhomeasupenabled(true); getactionbar().sethomebuttonenabled(true); // actionbardrawertoggle ties the proper interactions // between sliding drawer , action bar app icon mdrawertoggle = new actionbardrawertoggle( this, /* host activity */ mdrawerlayout, /* drawerlayout object */ r.drawable.ic_drawer, /* nav drawer image replace 'up' caret */ r.string.drawer_open, /* "open drawer" description accessibility */ r.string.drawer_close /* "close drawer" description accessibility */ ) { public void ondrawerclosed(view view) { getactionbar().settitle(mtitle); invalidateoptionsmenu(); // creates call onprepareoptionsmenu() } public void ondraweropened(view drawerview) { getactionbar().settitle(mdrawertitle); invalidateoptionsmenu(); // creates call onprepareoptionsmenu() } }; mdrawerlayout.setdrawerlistener(mdrawertoggle); if (savedinstancestate == null) { selectitem(0); } } @override public boolean oncreateoptionsmenu(menu menu) { menuinflater inflater = getmenuinflater(); inflater.inflate(r.menu.main, menu); return super.oncreateoptionsmenu(menu); } /* called whenever call invalidateoptionsmenu() */ @override public boolean onprepareoptionsmenu(menu menu) { // if nav drawer open, hide action items related content view boolean draweropen = mdrawerlayout.isdraweropen(mdrawerlist); menu.finditem(r.id.action_websearch).setvisible(!draweropen); return super.onprepareoptionsmenu(menu); } @override public boolean onoptionsitemselected(menuitem item) { // action bar home/up action should open or close drawer. // actionbardrawertoggle take care of this. if (mdrawertoggle.onoptionsitemselected(item)) { return true;

} return true; default: return super.onoptionsitemselected(item); } } /* click listner listview in navigation drawer */ private class draweritemclicklistener implements listview.onitemclicklistener { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { selectitem(position); } } private void selectitem(int position) { // update main content replacing fragments fragment fragment = new planetfragment(); bundle args = new bundle(); args.putint(planetfragment.arg_planet_number, position);

int = getarguments().getint(arg_planet_number); string planet = getresources().getstringarray(r.array.planets_array)[i]; int imageid = getresources().getidentifier(planet.tolowercase(locale.getdefault()), "drawable", getactivity().getpackagename()); ((imageview) rootview.findviewbyid(r.id.image)).setimageresource(imageid); getactivity().settitle(planet); return rootview; } } } activity_main.xml:

make sure define different grups different ids.
for example, drawer_menu.xml:
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <group android:id="@+id/menu_top" android:checkablebehavior="single"> <item android:checked="true" android:id="@+id/drawer_item_timeline" android:icon="@drawable/ic_timer_grey600_24dp" android:title="@string/drawer_timeline"/> <item android:id="@+id/drawer_item_reports" android:icon="@drawable/ic_timetable_grey600_24dp" android:title="@string/drawer_reports"/> </group> <group android:id="@+id/menu_bottom" android:checkablebehavior="none"> <item android:id="@+id/drawer_item_settings" android:icon="@drawable/ic_settings_black_24dp" android:title="@string/drawer_settings" > </item> </group> </menu>
