I am using the Android Template Navigation Drawer Activity but if I change the title and add Fragments, if I click it doesn''t take me to the fragment [duplicate]

This question already has an answer here:
How is Android Studio Navigation Drawer navigating different Fragments?
(1 answer)
Closed 2 years ago.
I open a new Activity using Android template for Navigation Drawer Activity.
When I click on the default Navigation drawer it shows the different fragment.
I have changed the title of the options in Navigation Drawer.
But if I click on then, it doesn't take me to the Fragment.
I cannot find any itemSelected or onClick methods in the Main Activity of the template where I can change the code to show new Fragments.
Please help how can I adjust the code to get my own fragments.

How to setup default navigation drawer and select different fragments?

I am novice developer and I'm integrating default (ready-made) Navigation drawer in my app with androidx. I'm having problem with navigating fragments as it doesn't work when I click on the drawer menu items. There are two fragments which are linked with their id's and set onClick listener, but it doesn't work. It just shows the main fragment but doesn't navigate to other fragments.
I'm not familiar with default functions like onCreateOptionsMenu(Menu menu) and onSupportNavigateUp() which are created by itself when I created the default drawer activity, so I just comment these functions and by following a tutorial I implement the NavigationView.OnNavigationItemSelectedListener which gives me onNavigationItemSelected(#NonNull MenuItem item) function where I wrote the code for navigate fragments. But it doesn't worked and when I debug, it shows that the onNavigationItemSelected(#NonNull MenuItem item) is not called.
public class FindBarber extends AppCompatActivity implements.
NavigationView.OnNavigationItemSelectedListener {
private AppBarConfiguration mAppBarConfiguration;
ActionBarDrawerToggle toggle;
Toolbar toolbar;
DrawerLayout drawer;
NavigationView navigationView;
int OPEN, CLOSE;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_find_barber);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawer = findViewById(R.id.drawer_layout);
navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
toggle = new ActionBarDrawerToggle(this, drawer, toolbar, OPEN, CLOSE);
drawer.addDrawerListener(toggle);
toggle.syncState();
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
/* mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_profile, R.id.nav_kutit_wallet,
R.id.nav_terms_of_use, R.id.nav_rate_the_app, R.id.nav_contact_us)
.setDrawerLayout(drawer)
.build();*/
/* NavController navController = Navigation.findNavController(this, R.id.content_frame);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);*/
FragmentManager fmanager = getSupportFragmentManager();
fmanager.beginTransaction().replace(R.id.content_frame, new GMap()).commit();
}
/*#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.find_barber, menu);
return true;
}
*/
// #Override
/* public boolean onSupportNavigateUp() {
*//*NavController navController = Navigation.findNavController(this, R.id.content_frame);*//*
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}*/
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId())
{
case R.id.nav_home:
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new GMap()).commit();
break;
case R.id.nav_profile:
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new Profile()).commit();
break;
}
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
There is no error message nor any app crash occurs. When I click navigation drawer item for navigating any fragment, it doesn't show anything except the main default fragment which I show in screen.

Call loadFragment(new Fragment(),"My Fragment") onNavigationItemSelected
public void loadFragment(Fragment fragment, String title_name){
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.customer_container,fragment,title_name);
fragmentTransaction.addToBackStack(fragment.getClass().getSimpleName());
fragmentTransaction.commit();
}

Please try this below line :
navigationView.getMenu().performIdentifierAction(R.id.posts, 0);

Nothing happens when item of navigation bar clicked

I have used google's sample navigation activity. In that I have modified the navigation bar items. I want to start a new activity when an item is clicked.
I have add onNavigationItemClicked event as well, still when I click on the item nothing happens.
public class MainActivity extends AppCompatActivity{
private AppBarConfiguration mAppBarConfiguration;
private TextView name, email;
private DrawerLayout drawer;
private Context context;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()){
case R.id.nav_my_printers:
Intent intent = new Intent(context, MyPrintersActivity.class);
startActivity(intent);
break;
case R.id.nav_settings:
Toast.makeText(context, "Not yet Implemented", Toast.LENGTH_SHORT).show();
}
return false;
}
});
View headerView = navigationView.getHeaderView(0);
name = headerView.findViewById(R.id.name);
email = headerView.findViewById(R.id.email);
name.setText(SessionClass.getUserInSession().getName());
email.setText(SessionClass.getUserInSession().getEmail());
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_my_printers, R.id.nav_settings)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
}

The line
NavigationUI.setupWithNavController(navigationView, navController);
Calls setNavigationItemSelectedListener internally to connect destinations to menu items. This overrides the OnNavigationItemSelectedListener view you've set.
Navigation supports <activity> destinations, allowing you to use the default setupWithNavController functionality out of the box. You'd add an activity destination to your graph that uses the same id as your menu item:
<activity
android:id="#+id/nav_my_printers"
android:name=".MyPrintersActivity"/>
Then the default setupWithNavController will call startActivity for you.

navigation drawer is not open when i click on the drawer how to solve this problem
is there any code is missing in my code.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.menu);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawer.openDrawer(START);
}
});

Try this,
<item
android:id="#+id/nav_camera"
android:icon="#drawable/ic_menu_camera"
android:title="#string/import" />
</group>
