Contents inside activity not working/not interactive after adding navigation drawer

enter image description hereI followed a tutorial on how to add a side navigation drawer but after adding it properly i can`t interact no more with the textedits/maps etc in my fragments, it´s not registering touch for that layout only for the drawer buttons itself.

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.

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.

NewSession_Activity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_session)
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final DrawerLayout drawer = findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
toggle.setDrawerIndicatorEnabled(false);
Class fragmentClass = SpeciesManager_Fragment.class;
Fragment fragment = null;
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e ) {
e.printStackTrace();
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.new_session_draw_frame, fragment);
fragmentTransaction.commit();
}
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

ViewPager in navigation drawer - Please give some advice

So overall idea is to in first (main page) have swiping gallery and I did it BUT when I choose options from navigation menu I'm having pager layout witch is my navigation drawer layout and its blank cuz just contain android.support.v4.view.ViewPager
