I need a side drawer layout, with a navigation view that contains a few buttons, doing different things. The issue I am having is that when I go to add ANYTHING within my "onNavigationItemSelected" listener, it never does anything. Basically, I assign the drawer+nav view, then do the ActionBarDrawerToggle with the proper items, and add the DrawerListener, then sync, then add the NavItemSelectedListener. This doesn't work. (Won't respond to clicks)
Here's the code:
private Toolbar toolbar;
private DrawerLayout drawerLayout;
private NavigationView navigationView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
toolbar = findViewById(R.id.main_toolbar);
setSupportActionBar(toolbar);
drawerLayout = findViewById(R.id.drawerlayout);
navigationView = findViewById(R.id.nav_view);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.open,R.string.close);
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
navigationView.setNavigationItemSelectedListener(this);
}
private void replaceFragment(Fragment fragment,String title) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction()
.setCustomAnimations(R.anim.slide_in,
R.anim.fade_out,
R.anim.fade_in,
R.anim.slide_out)
.setReorderingAllowed(true)
.replace(R.id.frameLayout, fragment,title)
.addToBackStack(null);
fragmentTransaction.commit();
}
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
replaceFragment(new Auto(),"auto");
return false;
}
If this doesn't give a clear answer, here is ALL of the code for this task.

I have tried using a switch statement to detect which ID clicked the Item, but none worked. Then I tried making it so that ANY item that clicked the navigationView made the entire screen swap fragments. This did not work. Then, I tried getting a Toast.makeText() to show up when I clicked ANY Item, this did not work. I'm expecting the bug to be somewhere within my NavView set up/on create code. EDIT: The answer was that within my XML, my NavigationView was before my actual content within the screen. You must put the nav View AFTER the layout, be it relative, constraint, etc. It should be the last thing in the drawer layout, basically. This answer was given to me by Mike M. Thanks Mike!
