Opening a new fragment on navigation bar

I have a navigation bar with fragment container inside. I have added an imageview in it.My problem is to replace fragment container with a new fragment when I choose an item in the navigation bar. When i choose an item on the navigation bar, it opens but fragment container still appear behind.
I would like to open an item on the navigation bar and the fragment container is fully overwritten by the new fragmement.

fragments overlaid in bottom navigation and drawer layout using viewpager 2 in android app

I'm almost new to programming in Android and there are still things that I don't handle very well. Now I'm doing a project in Android using java that has me half frustrated since I've been trying to find and fix a problem for WEEKS but I still can't identify what it is. The app consists of a view that contains a drawer layout with a series of "options", it also contains a viewpager2 and a bottom navigation with 2 other "options." The error appears when I press the bottom navigation tabs since the two fragments they overlap each other, the same happens when I select an option from the navigation drawer, the fragments are superimposed, then I leave you part of my code so that I hope you can help me, thank you very much for taking the time to help me.

Toolbar menu being cleared after being set (When activity is started)

Toolbar menu is inflated in fragment but then cleared later.
When activity is first created (or rotated) the toolbar menu is inflated properly in the fragment, but then gets cleared before it can be displayed.
I set the toolbar menu in my fragment's onActivityCreated, and it stays set through onResume in the activity. The next call I've found is in onCreateOptionsMenu in the activity, but at this point toolbar.getMenu().size() = 0
Somewhere between onResume and onCreateOptionsMenu the toolbar menu is getting reset.
Edit:
I'm not sure what is necessary to reproduce it, but here is all(?) of the relevant code.
Activity:
private Toolbar toolbar;
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;
private FloatingActionButton fab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_main);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
fab = findViewById(R.id.main_fab);
drawer = findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(this, drawer,toolbar,R.string.nav_drawer_open,R.string.nav_drawer_close);
drawer.addDrawerListener(toggle);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
if (savedInstanceState == null) {
showFragment(ScheduleFragment.newInstance());
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(toggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
CharSequence retainTitle = toolbar.getTitle();
super.onPostCreate(savedInstanceState);
toggle.syncState();
toolbar.setTitle(retainTitle);
}
Fragment:
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
toolbar = ((MainActivity)getActivity()).getToolbar();
setMenuAction(MENU_ACTION_DELETE);
}
protected void setMenuAction(int menuAction) {
Log.d(logger, "setting the menu");
switch(menuAction) {
case MENU_ACTION_DELETE:
toolbar.getMenu().clear();
toolbar.inflateMenu(R.menu.menu_delete);
break;
case MENU_ACTION_NONE:
Log.d(logger, "clearing menu");
toolbar.getMenu().clear();
break;
}
}

The problem in my current code as posted was the line setSupportActionBar(toolbar);
This was not needed, and was in fact causing the troubling lifecycle problems stated above.

i have bottom navigation and navigation drawer and i set home screen fragment as default

i have bottom navigation and navigation drawer and i set home screen fragment as default
now problem is when i run my app on Emulator hamburger icon and bottom navigation is showing and home Fragment by default
when i click to hamburger icon its not working
when i remove default home fragment then navigation drawer is working
How to solve this Problem so both navigationDrawer and bottom navigation will work

DrawerLayout mDrawerLayout;
ActionBarDrawerToggle mToggle;

#Override

bottomNavigationView = findViewById(R.id.homeScreenBottomNavigation);
bottomNavigationView.setOnNavigationItemSelectedListener(bottomNavListener);
// getSupportFragmentManager().beginTransaction().replace(R.id.homeScreenframeLayout, new HomeFragment()).commit();
mDrawerLayout = findViewById(R.id.HomeScreenDrawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
private BottomNavigationView.OnNavigationItemSelectedListener bottomNavListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
Fragment selectedFragment = null;
switch (menuItem.getItemId()) {
case R.id.bottomNavHome:
selectedFragment = new HomeFragment();
break;
case R.id.bottomNavAdd:
selectedFragment = new AddFragment();
break;

The issue is with your ActivityHomeScreen.xml. You have to make DrawerLayout as the parent view. Inside that you have to place BottomNavigationDrawer and remaining code.
And You havent created custom appbar for naviagtion drawer(it now comes with navigation drawer template)
Your ActivityHomeScreen.xml should look like this:
ActivityHomeScree.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
Now create a layout file app_bar_main.xml. Inside it create a toolbar and place your frameLayout here.
app_bar_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!--
Place your frameLayout here
-->
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="bottom"
app:menu="#menu/navigation" />
</android.support.design.widget.CoordinatorLayout>
Now both Navdrawer and BottomNavigationDrawer should work.

Using data binding inside of a Drawer Layout, where the drawer holds a fragment

I have a Navigation Drawer Activity, however, I'm using a Fragment inside of the drawer. I can't get both data binding and the fragment working together. With the example code the data binding doesn't work. If I change binding = ContentNewSessionBinding.inflate(getLayoutInflater()) to binding = DataBindingUtil.setContentView(this, R.layout.content_new_session_); I get an error that a view cannot be found the fragment.

setContentView(R.layout.activity_new_session)

setSupportActionBar(toolbar);
final DrawerLayout drawer = findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(

fragmentTransaction.replace(R.id.new_session_draw_frame, fragment);

ContentNewSessionBinding binding = ContentNewSessionBinding.inflate(getLayoutInflater());
binding.setWeatherModel(MainActivity.weatherModel);
}

You should try to move that FrameLayout in your activity_new_session.xml outside the NavigationView, between the toolbar layout and the NavigationView is the place for the fragment container and then you can add to your NavigationView:
app:headerLayout="YourHeaderLayout"
in case you want to have a header in your DrawerLayout
app:menu="YourMenuXml"
where you have the items that will show on your DrawerLayout
