This is how I do it to return to the right fragment otherwise if you have several fragments on the same level it would return to the first one if you don  t override the toolbar back button behavior   toolbar setNavigationOnClickListener new View OnClickListener              Override         public void onClick View view                finish

This is how I implemented it pre-material design and it seems to still work now I ve switched to the new Toolbar  In my case I want to log the user in if they attempt to open the side nav while logged out   and catch the event so the side nav won t open   In your case you could not return true     Override public boolean onOptionsItemSelected MenuItem item        if   isLoggedIn    amp  amp  item getItemId      android R id home            login            return true            return mDrawerToggle onOptionsItemSelected item     super onOptionsItemSelected item

If you want to know when home is clicked is an AppCompatActivity then you should try it like this   First tell Android you want to use your Toolbar as your ActionBar   setSupportActionBar toolbar     Then set Home to be displayed via setDisplayShowHomeEnabled like this   getSupportActionBar   setDisplayShowHomeEnabled true     Finally listen for click events on android R id home like usual    Override public boolean onOptionsItemSelected MenuItem menuItem        if  menuItem getItemId      android R id home            Timber d  Home pressed              return super onOptionsItemSelected menuItem       If you want to know when the navigation button is clicked on a Toolbar in a class other than AppCompatActivity you can use these methods to set a navigation icon and listen for click events on it  The navigation icon will appear on the left side of your Toolbar where the the  home  button used to be    toolbar setNavigationIcon getResources   getDrawable R drawable ic nav back    toolbar setNavigationOnClickListener new View OnClickListener          Override     public void onClick View v            Log d  cek    home selected                If you want to know when the hamburger is clicked and when the drawer opens  you re already listening for these events via onDrawerOpened and onDrawerClosed so you ll want to see if those callbacks fit your requirements

I think the correct solution with support library 21 is the following     action bar is def resource of appcompat      if you have not provided your own toolbar I mean   Toolbar toolbar    Toolbar  findViewById R id action bar   if  toolbar    null           change home icon if you wish     toolbar setLogo this getResValues   homeIconDrawable         toolbar setOnClickListener new View OnClickListener              Override         public void onClick View view                  catch here title and home icon click

The easiest approach we could do is change the home icon to a known icon and compare drawables  because  android R id home icon can differ to different api versions   so set a toolbar as actionbar SetSupportActionBar  toolbar     toolbar NavigationIcon   your known drawable here      for  int i   0  i  lt   toolbar ChildCount  i                                  View v    toolbar GetChildAt i                   if  v is ImageButton                                        ImageButton imageButton   v as ImageButton                       if  imageButton Drawable GetConstantState   Equals  bookMarkIcon GetConstantState                                                    here v is the widget that contains the home  icon you can add your click events here

Try this code   Override public boolean onOptionsItemSelected MenuItem item        int id   item getItemId        if id    android R id home             You can get            return super onOptionsItemSelected item       Add below code to your onCreate   metod  ActionBar ab   getSupportActionBar        ab setDisplayHomeAsUpEnabled true

I changed the DrawerLayout a bit to get the events and be able to consume and event  such as if you want to use the actionToggle as back if you are in detail view   public class ListenableDrawerLayout extends DrawerLayout        private OnToggleButtonClickedListener mOnToggleButtonClickedListener      private boolean mManualCall       public ListenableDrawerLayout Context context            super context              public ListenableDrawerLayout Context context  AttributeSet attrs            super context  attrs              public ListenableDrawerLayout Context context  AttributeSet attrs  int defStyle            super context  attrs  defStyle                         Sets the listener for the toggle button                param mOnToggleButtonClickedListener             public void setOnToggleButtonClickedListener OnToggleButtonClickedListener mOnToggleButtonClickedListener            this mOnToggleButtonClickedListener   mOnToggleButtonClickedListener                        Opens the navigation drawer manually from code lt br gt          lt b gt NOTE   lt  b gt Use this function instead of the normal openDrawer method                param drawerView             public void openDrawerManual View drawerView            mManualCall   true          openDrawer drawerView                         Closes the navigation drawer manually from code lt br gt          lt b gt NOTE   lt  b gt Use this function instead of the normal closeDrawer method                param drawerView             public void closeDrawerManual View drawerView            mManualCall   true          closeDrawer drawerView                Override     public void openDrawer View drawerView                Check for listener and for not manual open         if   mManualCall  amp  amp  mOnToggleButtonClickedListener    null                    Notify the listener and behave on its reaction             if  mOnToggleButtonClickedListener toggleOpenDrawer                      return                                      Manual call done         mManualCall   false              Let the drawer layout to its stuff         super openDrawer drawerView               Override     public void closeDrawer View drawerView                Check for listener and for not manual close         if   mManualCall  amp  amp  mOnToggleButtonClickedListener    null                    Notify the listener and behave on its reaction             if  mOnToggleButtonClickedListener toggleCloseDrawer                      return                                      Manual call done         mManualCall   false              Let the drawer layout to its stuff         super closeDrawer drawerView                         Interface for toggle button callbacks             public static interface OnToggleButtonClickedListener                           The ActionBarDrawerToggle has been pressed in order to open the drawer                        return true if we want to consume the event  false if we want the normal behaviour                     public boolean toggleOpenDrawer                            The ActionBarDrawerToggle has been pressed in order to close the drawer                        return true if we want to consume the event  false if we want the normal behaviour                     public boolean toggleCloseDrawer

For anyone looking for a Xamarin implementation  since events are done differently in C    I simply created this NavClickHandler class as follows   public class NavClickHandler   Java Lang Object  View IOnClickListener       private Activity mActivity      public NavClickHandler Activity activity                this mActivity   activity            public void OnClick View v                DrawerLayout drawer    DrawerLayout mActivity FindViewById Resource Id drawer layout           if  drawer IsDrawerOpen GravityCompat Start                         drawer CloseDrawer GravityCompat Start                     else                       drawer OpenDrawer GravityCompat Start                       Then  assigned a custom hamburger menu button like this           SupportActionBar SetDisplayHomeAsUpEnabled true           SupportActionBar SetDefaultDisplayHomeAsUpEnabled false           this drawerToggle DrawerIndicatorEnabled   false          this drawerToggle SetHomeAsUpIndicator Resource Drawable MenuButton     And finally  assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier           this drawerToggle ToolbarNavigationClickListener   new NavClickHandler this     And then you ve got a custom menu button  with click events handled
