Android Change Navigation Drawer Menu Items Text programmatically

You can change the title of Navigation Menu Item programmatically by adding following lines in MainActivity.java file.

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    ...    //other stuff here    ...    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);    // get menu from navigationView    Menu menu = navigationView.getMenu();    // find MenuItem you want to change    MenuItem nav_camara = menu.findItem(R.id.nav_camara);    // set new title to the MenuItem    nav_camara.setTitle("NewTitleForCamera");    // do the same for other MenuItems    MenuItem nav_gallery = menu.findItem(R.id.nav_gallery);    nav_gallery.setTitle("NewTitleForGallery");    // add NavigationItemSelectedListener to check the navigation clicks    navigationView.setNavigationItemSelectedListener(this);}

This works fine for me. Hope it'll help you.

Change the code like below in case you rename or remove item from navigation menu drawer list

  NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);    if (navigationView != null) {        Menu menu = navigationView.getMenu();        menu.findItem(R.id.nav_profile).setTitle("My Account");        menu.findItem(R.id.nav_mng_task).setTitle("Control Task");        //menu.findItem(R.id.nav_pkg_manage).setVisible(false);//In case you want to remove menu item        navigationView.setNavigationItemSelectedListener(this);    }

If you have a layout in navigation drawer menu as an item and you want to change it programmatically, this code snippet will help you:

MenuItem nav = navigationView.getMenu().findItem(R.id.nav_close_app);nav.setActionView(R.layout.item_navigationdrawer_close_app);
