android - Clicking hamburger icon on Toolbar does not open Navigation Drawer -

i have simple android.support.v7.widget.toolbar , trying open navigationdrawer pressing "hamburger" icon in top left corner. "hamburger" button visible, , when start pull left see animation on button pressing button not open/close navigationdrawer expect. have followed [google documentation][1] , still not able figure out. sorry confusion, below simplified code attempting use:

public class mainactivity extends appcompatactivity implements     view.onclicklistener,     googleapiclient.connectioncallbacks,     googleapiclient.onconnectionfailedlistener {    @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_main);       toolbar toolbar = (toolbar) findviewbyid(r.id.my_toolbar);     setsupportactionbar(toolbar);     getsupportactionbar().setdisplayhomeasupenabled(true);        toolbar.setnavigationonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             log.d("nick", "button button button..................");         }     });          mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer);         navigationview n = (navigationview) findviewbyid(r.id.nav);         mdrawerlayout.setonclicklistener(new view.onclicklistener(){             @override             public void onclick(view v) {                 log.d("nick", "button button button..................");             }         });          //mdrawerlayout.setdrawerlistener(mdrawertoggle);         n.setnavigationitemselectedlistener(new navigationview.onnavigationitemselectedlistener() {             @override             public boolean onnavigationitemselected(menuitem menuitem) {                 switch (menuitem.getitemid()) {                     ////.......                  }                 mdrawerlayout.closedrawers();  // close drawer                 return true;             }         });  @override public boolean onoptionsitemselected(menuitem item) {      log.d("nick","cwecnewkvneripnviewnfvipewnvipewnvpiewnvpiewnvpiewnvpirwnvprwvpo");     switch (item.getitemid()) {         case android.r.id.home:             mdrawerlayout.opendrawer(gravitycompat.start);  // open drawer             log.d("nick","cwecnewkvneripnviewnfvipewnvipewnvpiewnvpiewnvpiewnvpirwnvprwvpo");             return true;      }            return super.onoptionsitemselected(item);   }  @override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);     mdrawertoggle.onconfigurationchanged(newconfig); }    @override public boolean oncreateoptionsmenu(menu menu) {     getmenuinflater().inflate(r.menu.drawer, menu);     return true; }   } 

}

and not of log debug statements when running.

this issue have: https://stackoverflow.com/a/26636045/1489990. i've followed , doesn't work.

it understanding setnavigationonclicklistener called when hamburger icon pressed, , focusing efforts event handled because when press button not log statement. let me know if idea incorrect. https://developer.android.com/reference/android/widget/toolbar.html#setnavigationonclicklistener(android.view.view.onclicklistener)

see answer similar post.

basically, skip actionbardrawertoggle if don't need other things (like callbacks). can remove code , implement open/close drawer behavior, this:

@override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {        case android.r.id.home:             mdrawerlayout.opendrawer(gravitycompat.start);  // open drawer             return true;         ....     }     return super.onoptionsitemselected(item); } 

the code segment above works whether or not you're using navigationview. if using navigation view, in navigationview click listener:

navigationview.setnavigationitemselectedlistener(     new navigationview.onnavigationitemselectedlistener() {         @override         public boolean onnavigationitemselected(menuitem menuitem) {             // handle menu item clicks here.             drawerlayout.closedrawers();  // close drawer             return true;         }     }); 

update:

also, make sure activity extending appcompatactivity (and not actionbaractivity). see my answer here more info.

update2:

i debugged revised code. try this. should work now. read inline comments see changed , why:

import android.os.bundle; import android.support.design.widget.navigationview; import android.support.v4.view.gravitycompat; import android.support.v4.widget.drawerlayout; import android.support.v7.app.appcompatactivity; import android.support.v7.widget.toolbar; import android.util.log; import android.view.menu; import android.view.menuitem;  public class mainactivity extends appcompatactivity { //        view.onclicklistener, //        googleapiclient.connectioncallbacks, //        googleapiclient.onconnectionfailedlistener {       drawerlayout mdrawerlayout;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          toolbar toolbar = (toolbar) findviewbyid(r.id.my_toolbar);         setsupportactionbar(toolbar);         // missing sethomeasupindicator         getsupportactionbar().sethomeasupindicator(r.drawable.ic_menu);         getsupportactionbar().setdisplayhomeasupenabled(true);          // removed toolbar , drawer click listeners.         // they're not needed open drawer.         // drawer opens onoptionsitemselected().          mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer);         navigationview n = (navigationview) findviewbyid(r.id.nav);         n.setnavigationitemselectedlistener(new navigationview.onnavigationitemselectedlistener() {             @override             public boolean onnavigationitemselected(menuitem menuitem) {                 switch (menuitem.getitemid()) {                     ////.......                  }                 mdrawerlayout.closedrawers();  // close drawer                 return true;             }         });     }      @override     public boolean onoptionsitemselected(menuitem item) {          log.d("nick", "cwecnewkvneripnviewnfvipewnvipewnvpiewnvpiewnvpiewnvpirwnvprwvpo");         switch (item.getitemid()) {             // drawer/hamburger button             case android.r.id.home:                 mdrawerlayout.opendrawer(gravitycompat.start);  // open drawer                 log.d("nick", "cwecnewkvneripnviewnfvipewnvipewnvpiewnvpiewnvpiewnvpirwnvprwvpo");                 return true;          }         return super.onoptionsitemselected(item);     } }  // removed onconfigurationchanged(). // it's not needed since you're no longer using actionbardrawertoggle.  

update3: problem layout

looking @ activitymain.xml, see toolbar outside of drawerlayout. can't that. toolbar needs child of drawerlayout in order toolbar find proper context.

you need make drawerlayout root of activity. here's documentation, , specific quote is:

to add navigation drawer, declare user interface drawerlayout object root view of layout. inside drawerlayout, add 1 view contains main content screen (your primary layout when drawer hidden) , view contains contents of navigation drawer.

so basically, change activitymain.xml this:

<android.support.v4.widget.drawerlayout     android:id="@+id/drawer"     ... >      <relativelayout         android:id="@+id/d"         ...>          <android.support.v7.widget.toolbar             android:id="@+id/my_toolbar"             ... />          <!-- other content goes here -->      </relativelayout>      <android.support.design.widget.navigationview         android:id="@+id/nav"         ... />  </android.support.v4.widget.drawerlayout> 

hopefully, takes care of problems.
