This is a new Drawerlayout project using Android studio to run out after the effect (no Android studio friends hurriedly go to download a bar).

After the generated code is a bit confusing, a little tidying up, then first look at the layout file

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:app= "Http://schemas.android.com/apk/res-auto"       xmlns:tools= "http// Schemas.android.com/tools "      android:id=" @+id/drawer_layout "       android:layout_width= "Match_parent"       android:layout_ height= "Match_parent"       android:fitssystemwindows= "true"        tools:opendrawer= "Start" >        <include           layout= "@layout/app_bar_main"            android:layout_width= "Match_parent"            android:layout_height= "Match_parent"  />        < android.support.design.widget.navigationview           Android:id= "@+id/nav_view"           android:layout_width= " Wrap_content "          android:layout_height=" Match_parent "           android:layout_gravity= "Start"            android:fitssystemwindows= "true"            app:headerlayout= "@layout/nav_header_main"            app:menu= "@menu/activity_main_drawer"  />    </ Android.support.v4.widget.drawerlayout>

If App_bar_main.xml is referenced in Drawerlayout, Heraderlayout represents the green part of the slide-in menu in the Navigationview control, and menu represents the item.

App_bar_main.xml:

<?xml version= "1.0"  encoding= "Utf-8"?>  < Android.support.design.widget.coordinatorlayout xmlns:android= "Http://schemas.android.com/apk/res/android "      xmlns:app="     "Http://schemas.android.com/apk/res-auto"    xmlns:tools= "Http://schemas.android.com/tools"       android: Layout_width= "Match_parent"       android:layout_height= "Match_parent"        android:fitssystemwindows= "true"       tools: context= "Com.lg.slidingmenudemo.MainActivity" >        < Android.support.design.widget.appbarlayout          android: Layout_width= "Match_parent"           android:layout_height= " Wrap_content "          andRoid:theme= "@style/apptheme.appbaroverlay" >             <android.support.v7.widget.Toolbar               android:id= "@+id/toolbar"                android:layout_width= "Match_parent"                android:layout_height= "Attr/actionbarsize"                android:background= "Attr/colorprimary"                app:popuptheme= "@style/ Apptheme.popupoverlay " />        </ Android.support.design.widget.appbarlayout>        <include  layout= "@layout/content_main"  />    </android.support.design.widget.coordinatorlayout> 

App_bar_main.xml in the toolbar can set the top title, feel reference content_main.xml troublesome words can be directly in the inside write layout, delete Content_main.xml can.

Mainactivity:

public class mainactivity extends appcompatactivity           implements NavigationView.OnNavigationItemSelectedListener {          @Override       protected void  OnCreate (bundle savedinstancestate)  {           Super.oncreate (savedinstancestate);           setcontentview ( R.layout.activity_main);          toolbar toolbar  =  (Toolbar)  findviewbyid (R.id.toolbar);           Setsupportactionbar (toolbar);             //Control side-slip menu          DrawerLayout drawer =  (Drawerlayout)  findviewbyid (R.id.drawer_layout);           actionbardrawertoggle toggle =  new actionbardrawertoggle (                   this, drawer, toolbar, r.string.navigation_drawer_open,  r.string.navigation_drawer_close);           Drawer.setdrawerlistener (toggle);           toggle.syncstate ( );             //setting selection events for Navigationview menu           NavigationView navigationView =  (Navigationview )  findviewbyid (R.id.nav_view);           Navigationview.setnavigationitemselectedlistener (This);      }           //back Key       @Override       public void  Onbackpressed ()  {          drawerlayout drawer  =  (drawerlayout)  findviewbyid (r.id.drawer_layout);           if  (Drawer.isdraweropen (gravitycompat.start))  {               drawer.closedrawer (Gravitycompat.start);           } else {               super.onbackpressed ();           }      }        @ Suppresswarnings ("Statementwithemptybody")        @Override        public boolean onnavIgationitemselected (Menuitem item)  {          int  id = item.getitemid ();             if  (Id == r.id.nav_camera)  {             } else if  (id == r.id.nav_gallery)  {             } else if  (id == r.id.nav_slideshow)  {             } else if  (id ==  r.id.nav_manage)  {            }  else if  (Id == r.id.nav_share)  {             } else if  (id == r.id.nav_send)  {              }            //close the slide-out menu           DrawerLayout drawer =  (drawerlayout )  findviewbyid (r.id.drawer_layout);           Drawer.closedrawer (Gravitycompat.start);           return  true;      }  }

You can also customize the menu

<?xml version= "1.0"  encoding= "Utf-8"? >  <menu xmlns:android= "http// Schemas.android.com/apk/res/android ">        <group android : checkablebehavior= "single" >          <item               android:id= "@+id/nav_camera"               android:icon= "@drawable/ic _menu_camera "              android:title = "Import"  />          <item               android:id= "@+id/nav_gallery"                android:icon= "@drawable/ic_menu_ Gallery "&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBsp;        android:title= "Gallery"  />           <item               android:id= "@+id/nav_slideshow"                android:icon= "@drawable/ic_menu_slideshow"                android:title= "Slideshow"  />           <item               android:id= "@+id/nav_manage"                android:icon= "@drawable/ic_menu_manage"                android:title= "Tools"  />      </ Group>  &nbsP;     <item android:title= "Communicate" >           <menu>               <item                   android:id= "@+id/nav_share"                    android:icon= "@drawable/ic_menu_share"                    android:title= "Share " />              <item                   android: Id= "@+id/nav_send"                    android:icon= "@drawable/ic_menu_send"                    android:title= "Send"  />           </menu>      </item>    </ Menu>

icon in item is the menu item icons Resource Id,title is the menu item title (the text that the menu item displays), which can be customized according to the requirements
