<android.support.v4.widget.drawerlayout     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:id="@+id/drawer_layout"     android:layout_height="match_parent"     android:layout_width="match_parent"     android:fitssystemwindows="true">      <include android:id="@+id/toolbar" layout="@layout/toolbar" />      <framelayout         android:id="@+id/frame_container"         android:layout_width="match_parent"         android:layout_height="match_parent" />      <android.support.design.widget.navigationview         android:id="@+id/nav_view"         android:layout_height="match_parent"         android:layout_width="wrap_content"         android:layout_gravity="start"         android:fitssystemwindows="true"         app:headerlayout="@layout/navigation_header"         app:menu="@menu/drawer_view"/>  </android.support.v4.widget.drawerlayout> 

toolbar:

<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="?attr/actionbarsize"     android:background="?attr/colorprimary"     android:elevation="4dp"     android:fitssystemwindows="true"     app:popuptheme="@style/menuoverlay" /> 

mainactivity:

public class mainactivity extends appcompatactivity {     private drawerlayout mdrawerlayout;     public static toolbar toolbar;      public static fragmentmanager supportfragmentmanager;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);          setcontentview(r.layout.activity_main);          setuptoolbar();         setupnavdrawer();          mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout);          navigationview navigationview = (navigationview) findviewbyid(r.id.nav_view);         if (navigationview != null) {             setupdrawercontent(navigationview);         }     }      @override     public boolean oncreateoptionsmenu(menu menu) {         getmenuinflater().inflate(r.menu.menu_main, menu);          return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         switch (item.getitemid()) {             case android.r.id.home:                 mdrawerlayout.opendrawer(gravitycompat.start);                 return true;         }          return super.onoptionsitemselected(item);     }      private void setupdrawercontent(navigationview navigationview) {         navigationview.setnavigationitemselectedlistener(new navigationview.onnavigationitemselectedlistener() {                     @override                     public boolean onnavigationitemselected(menuitem menuitem) {                         menuitem.setchecked(true);                         mdrawerlayout.closedrawers();                         return true;                     }                 });     }      private void setuptoolbar() {         toolbar = (toolbar) findviewbyid(r.id.toolbar);         if (toolbar != null) {             setsupportactionbar(toolbar);         }     }      private void setupnavdrawer() {         if (toolbar != null) {             getsupportactionbar().setdisplayhomeasupenabled(true);             toolbar.setnavigationicon(r.drawable.ic_menu);             toolbar.setnavigationonclicklistener(new view.onclicklistener() {                 @override                 public void onclick(view v) {                     mdrawerlayout.opendrawer(gravitycompat.start);                 }             });         }     } } 

the main content view must first child inside drawerlayout, have change activity_main layout to:

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/drawer_layout" android:layout_height="match_parent" android:layout_width="match_parent" android:fitssystemwindows="true">  <linearlayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <include android:id="@+id/toolbar" layout="@layout/test_toolbar" />      <framelayout         android:id="@+id/frame_container"         android:layout_width="match_parent"         android:layout_height="match_parent" />  </linearlayout>  <android.support.design.widget.navigationview     android:id="@+id/nav_view"     android:layout_height="match_parent"     android:layout_width="wrap_content"     android:layout_gravity="start"     android:fitssystemwindows="true"     app:headerlayout="@layout/navigation_header"     app:menu="@menu/drawer_view"/>  </android.support.v4.widget.drawerlayout>
