Use the code below   navigationView getMenu   getItem 0  setChecked true     Call this method after you call setNavDrawer      The getItem int index  method gets the MenuItem then you can call the setChecked true   on that MenuItem  all you are left to do is to find out which element index does the default have  and replace the 0 with that index   You can select highlight  the item by calling  onNavigationItemSelected navigationView getMenu   getItem 0      Here is a reference link  http   thegeekyland blogspot com 2015 11 navigation-drawer-how-set-selected-item html  EDIT Did not work on nexus 4  support library revision 24 0 0  I recommend use   navigationView setCheckedItem R id nav item    answered by  kingston below

You have to call 2 functions for this   First  for excuting the commands you have implemented in onNavigationItemSelected listener   onNavigationItemSelected navigationView getMenu   getItem R id nav camera      Second  for changing the state of the navigation drawer menu item to selected  or checked    navigationView setCheckedItem R id nav camera     I called both functions and it worked for me

Easiest way is to select it from xml as follows    lt menu gt      lt group android checkableBehavior  single  gt            lt item               android checked  true                android id    id nav home                android icon   drawable nav home                android title   string main screen title home    gt    Note the line android checked  true

There are always problems with Googles  oh so great  support libs  If you want to check an item without downgrading your support libs version  just set checkable before setting checked state    MenuItem item   drawer getMenu   findItem R id action something   item setCheckable true   item setChecked true     It might also work if you set checkable in the menu xml files

API 23 provides the following method   navigationView setCheckedItem R id nav item id     However  for some reason this function did not cause the code behind the navigation item to run  The method certainly highlights the item in the navigation drawer  or  checks  it  but it does not seem to call the OnNavigationItemSelectedListener resulting in a blank screen on start-up if your start-up screen depends on navigation drawer selections  It is possible to manually call the listener  but it seems hacky   if  savedInstanceState    null  this onNavigationItemSelected navigationView getMenu   getItem 0      The above code assumes    You have implemented NavigationView OnNavigationItemSelectedListener in your activity You have already called  navigationView setNavigationItemSelectedListener this   The item you wish to select is located in position 0

First of all create colors for selected item  Here https   stackoverflow com a 30594875 1462969 good example  It helps you to change color of icon  For changing background of all selected item add in your values style xml file  this      lt item name  selectableItemBackground  gt  drawable selectable item background lt  item gt    Where selectable item background should be declared in drawable selectable item background xml      lt  xml version  1 0  encoding  utf-8   gt       lt selector xmlns android  http   schemas android com apk res android  gt       lt item android drawable   color accent translucent        android state pressed  true    gt       lt item android drawable   android color transparent    gt      lt  selector gt    Where color can be declared in style xml    lt color name  accent translucent  gt  80FFEB3B lt  color gt    And after this         The main navigation menu with user-specific actions         mainNavigationMenu     NavigationView  findViewById R id main drawer           mainNavigationMenu  setNavigationItemSelectedListener new NavigationView OnNavigationItemSelectedListener                  Override             public boolean onNavigationItemSelected MenuItem menuItem                    mainNavigationMenu  getMenu   findItem itemId  setChecked true                   return true                              As you see I used this mainNavigationMenu  getMenu   findItem itemId  setChecked true   to set selected item  Here navigationView    lt android support design widget NavigationView         android id    id main drawer          android layout width  wrap content          android layout height  match parent          android layout gravity  start          app headerLayout   layout header main navigation menu          app itemIconTint   color state list          app itemTextColor   color primary          app menu   menu main menu drawer   gt
