Home button not showing up in navigation drawer android -


i'm using navigation drawer project, working fine 1 small problem, arrow displayed not home button. tried found in documentations, forums , here nothing working.

what tried far:

mdrawertoggle.syncstate();  actionbar.setdisplayshowtitleenabled(true); actionbar.setdisplayhomeasupenabled(true);     @override     public void onpostcreate(bundle savedinstancestate, persistablebundle persistentstate) {         super.onpostcreate(savedinstancestate, persistentstate);         mnavigationdrawerfragment.getmdrawertoggle().syncstate();     }  actionbar actionbar = getsupportactionbar();   actionbar.setnavigationmode(actionbar.navigation_mode_standard); actionbar.setdisplayshowtitleenabled(true); actionbar.setdisplayhomeasupenabled(true); actionbar.sethomebuttonenabled(true); actionbar.settitle(mtitle);

navigationdrawerfragment:

// defer code dependent on restoration of previous instance state.         mdrawerlayout.post(new runnable() {             @override             public void run() {                 mdrawertoggle.syncstate();             }         });

i have been busy making simple app navigation drawer..don't use template there deprecated methods.. working.. created example.. try this..

your mainactivity

public class mainactivity extends actionbaractivity {     toolbar toolbar;     protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     toolbar = (toolbar) findviewbyid(r.id.app_toolbar);     setsupportactionbar(toolbar);       profile profile = (profile) getsupportfragmentmanager().findfragmentbyid(r.id.profilefragmentinmain);     profile.setup((drawerlayout) findviewbyid(r.id.drawer),toolbar);  }  @override public boolean onoptionsitemselected(menuitem item) {     return super.onoptionsitemselected(item); }

this fragment..

public class profile extends fragment {  actionbardrawertoggle drawertoggle; drawerlayout mdrawerlayout;  @nullable @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {      view view = inflater.inflate(r.layout.profile, container, false);     return view; }  public void setup(drawerlayout drawerlayout, toolbar toolbar) {      mdrawerlayout = drawerlayout;     drawertoggle = new actionbardrawertoggle(getactivity(), drawerlayout, toolbar, r.string.open, r.string.close){          @override         public void ondraweropened(view drawerview) {             super.ondraweropened(drawerview);             getactivity().invalidateoptionsmenu();         }          @override         public void ondrawerclosed(view drawerview) {             super.ondrawerclosed(drawerview);             getactivity().invalidateoptionsmenu();         }          @override         public boolean onoptionsitemselected(menuitem item) {              if (item != null && item.getitemid() == android.r.id.home) {                 if (mdrawerlayout.isdraweropen(gravity.right)) {                     mdrawerlayout.closedrawer(gravity.right);                 } else {                     mdrawerlayout.opendrawer(gravity.right);                 }                 return true;             }             return false;         }      };     mdrawerlayout.setdrawerlistener(drawertoggle);       mdrawerlayout.post(new runnable(){          @override         public void run(){              drawertoggle.syncstate();         }      }); } }

this in classes..

now xml layouts..

activity_main.xml

 <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:id="@+id/drawer" android:layout_height="match_parent" >   <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical"     tools:context=".mainactivity">      <include         android:id="@+id/app_toolbar"         layout="@layout/toolbar"/> </linearlayout>  <fragment     android:id="@+id/profilefragmentinmain"     android:layout_width="240dp"     android:layout_height="match_parent"     android:layout_gravity="start"     app:layout="@layout/profile"     android:name="com.example.ajay.myapplication.profile"     tools:layout="@layout/profile"/>  </android.support.v4.widget.drawerlayout>

your profile.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" app:theme="@android:style/theme.holo.light.dialogwhenlarge.noactionbar">  </linearlayout>

your toolbar.xml

<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/app_toolbar" />
