I'm using navigation template of android studio in my project. I have two items to navigate through fragments and I added another item to exit the app via finish() method. The problem is this component doesn't use onNavigationItemSelected and when I try to use navigationView.setNavigationItemSelectedListener() my exit item works fine but fragment switching doesn't work any more.
Here's my code:
public class MainActivity extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
private ActivityMainBinding binding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
setSupportActionBar(binding.appBarMain.toolbar);
binding.appBarMain.fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = binding.drawerLayout;
NavigationView navigationView = binding.navView;
// 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_setting)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment_content_main);
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_content_main);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
}
I found the solution thanks to Martin Marconcini . Solution is :
NavigationUI.onNavDestinationSelected(dest, navController)
Here's the piece of code that helped me :
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull @NotNull MenuItem item) {
if (item.getItemId() == R.id.nav_exit) {
finish();
} else {
NavigationUI.onNavDestinationSelected(item, navController);
drawer.closeDrawers();
}
return false;
}
});
