How do i fix overlapping fragments

I have a top bar and a bottom bar. I want to go to certain places from the top menu and to certain places from the bottom menu. But these two parts overlap each other, how can I solve this in the fragment. I make Twitter-style bottom and top components, but the fragment is overwritten.
I searched for fragment removal code but I couldn't find it.
Can you tell me where I went wrong?
Thanks.

You will need to setup all over NavigationController.
Magic happens down below =)
setSupportActionBar(binding.appBarMain.toolbar);
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_gallery, R.id.nav_slideshow)
.setOpenableLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment_content_main);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
Also, don't forget about OnSupportNavigateUp to handle drawer layout icon clicks
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment_content_main);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}

Android - DrawerLayout only shows Back Arrow

I'm trying to build in a hamburger menu into my Android (Kotlin) application. I thought I followed all of the steps, but only the back arrow show, which does nothing. I can however slide the menu from the left.
I then started a new application and tried to start from scratch, with the same result. Again the statusbar is shown, with only the back arrow.
I'm can't seem to find what I'm doing wrong.
Here's my code

Change this line of code
setupActionBarWithNavController(navController, appBarConfiguration)
To this
toolbar.setupWithNavController(navController, appBarConfiguration)

You need to set ActionBarDrawerToggle to achieve this -
private lateinit var drawerToggle: ActionBarDrawerToggle
In onCreate method you need to initialize drawerToggle as below -
drawerToggle = ActionBarDrawerToggle(this, drawer, toolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close)
drawer.addDrawerListener(toggle)
toggle.setDrawerIndicatorEnabled(true)
toggle.syncState()

Thanks you for the suggestions. The answer of #KakyireLastBorn give me an idea. I changed the line
setupActionBarWithNavController(navController, appBarConfiguration)
to
toolbar.setupWithNavController(navController, drawerLayout)
This solved the issue !

Android Options menu shows up but is empty

I'm developing an Android app from "Navigation Drawer Activity" Template.
When I click on the Options menu, it shows an empty menu when it should show the Settings item.
I guess it could be because of the text color but I checked and for me it is not that.
Where is my error?

Thanks for your help!
EDIT: What I want vs what I get

Make adjustments to your menu XML file.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_settings"
android:title="#string/action_settings"
app:showAsAction="ifRoom" /> // this is the key
</menu>
Add this into your app's theme
<item name="android:actionMenuTextColor">#color/black</item>

Is it possible to centre the actionbar title from a fragment using AndroidX navigation?

Currently, I am using the Navigation component from Android and the actionbar title is displayed on the left. However, I kind of want it centralised to make things neater, is there any way to go about doing so?

Activity's code:
public class General extends AppCompatActivity {
private BottomNavigationView bottomNavigationView;
private NavController navController;
private AppBarConfiguration appBarConfiguration;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.general);
bottomNavigationView = findViewById(R.id.bottomNavigationView);
navController = Navigation.findNavController(this, R.id.fragment);
appBarConfiguration = new AppBarConfiguration.Builder(R.id.addFragment, R.id.homeFragment).build();
NavigationUI.setupWithNavController(bottomNavigationView, navController);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
}
}

<fragment

</navigation>

After a bit of searching, it seems like this did the trick. All I had to do was to add it to my Activity code.

As the fragments are a childs of Parent activity, so we can centralize or customize the title as we want on the Parent Activity.
Here is an example how to center the title without doing the iterate for all View widgets ...
override fun onCreate(savedInstanceState: Bundle?) {
setTheme(R.style.AppTheme);
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
navView = findViewById(R.id.nav_view)
navController = findNavController(R.id.nav_host_fragment)
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
val appBarConfiguration = AppBarConfiguration(
setOf(
R.id.navigation_home, R.id.navigation_settings, R.id.navigation_info
)
)
setupActionBarWithNavController(navController, appBarConfiguration)
navView.setupWithNavController(navController)
// Detect on where fragment we are, and custom the title from here
navController
.addOnDestinationChangedListener { nc: NavController, nd: NavDestination, args: Bundle? ->
when(nd.id){
R.id.navigation_home -> {
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM
supportActionBar?.setCustomView(R.layout.title_home_action_bar_layout)
}
R.id.navigation_settings -> {
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM
supportActionBar?.setCustomView(R.layout.title_settings_action_bar_layout)
}
R.id.navigation_info -> {
supportActionBar?.displayOptions = ActionBar.DISPLAY_SHOW_CUSTOM
supportActionBar?.setCustomView(R.layout.title_info_action_bar_layout)
}
}
}
}
For the custom centered title : title_settings_action_bar_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical">
<TextView
android:id="#+id/tvTitle"

android:layout_height="wrap_content"
android:gravity="center"
android:text="Settings Baby Watcher"
android:textColor="#FFFFFF" />
</LinearLayout>

You need to add when in onNavigationItemSelected as below
override fun onNavigationItemSelected(item: MenuItem): Boolean {
when(item.itemId){
R.id.youritemid-> {
Log.e("NAV","nav selected working")
return true
}
return true
}

Here I got the answer the problem is we should put our navigation view after the linear layout component inside the drawerlayout after all the content views at the end of the drawerLayout
