These are my layout files.
In brief, I've created a DrawerLayout inside which I've implemented my menu using NavigationView. One of the menu item is a switch and I want to add a .setOnCheckedChangeListener to this switch.
I've tried accessing the switch like this inside the onCreate() function of my activity:
val switch = binding.navView.menu.findItem(R.id.nav_theme) as SwitchCompat
switch.setOnCheckedChangeListener { _, isChecked ->
}
However, it is throwing an exception that MenuItem cannot be cast into a SwitchCompat.
I don't see any otherway to access this switch.

If you want a switch on your item, use actionViewClass to define the component.
And if a not mistaken you can remove app:actionLayout="#layout/theme_switch"
app:actionViewClass="androidx.appcompat.widget.SwitchCompat"

How to draw a line in menu item atctive

I want to put this little green line in the menu item that is active ... already has to create a shape and a custom style but no success ...
My activity_main_drawer.xml
<?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">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_ordem"
android:checked="true"
android:title="Home"/>
<item
android:id="#+id/nav_auto_infracao"
android:title="Payment Profile" />
<item
android:id="#+id/nav_apreensao_deposito"
android:title="Payment history" />
<item
android:id="#+id/nav_doacao"
android:title="My card" />
<item
android:id="#+id/nav_sincronia"
android:title="Frinds" />
</group>
</menu>

Try to use View to draw line.
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#android:color/black" />

One way to solve this is you can highlight the item by calling the following method to detect when to change the visibility and position the view:
onNavigationItemSelected(navigationView.getMenu().getItem(0));
Since you've mentioned you already have a shape and a custom style, put the view (here in this code below, selectedItemBottomView) inside the NavigationView in activity_main or the XML layout file where you've used the activity_main_drawer like this:
activity_main
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.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" />
<com.google.android.material.navigation.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="#menu/activity_main_drawer" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:id="#+id/selectedItemBottomView"
android:layout_width="match_parent"
android:layout_height="10dp"
android:background="#color/green" />
</LinearLayout>
</RelativeLayout>
</com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
On selected, change the visibility or position as per your requirement:
selectedItemBottomView.setVisibility(View.VISIBLE);
Hope this helps.

Toolbar does not display (briefly shows up before disappearing)

I am trying to make an action bar (through toolbar) with a navigation drawer, however I only manage to get the navigation drawer part working. When the app loads in the emulator, it does seem that the toolbar shows up on the screen for a fraction of a second before it disappears, showing a screen without a toolbar. How do i get the toolbar to show up/not disappear on load?
This is how it looks like:

As Ajay mentioned that DrawerLayout should only contain two layouts so I am editing some of your codes to fulfill the requirements and I think this would work just give it a try
main_layout.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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include
android:layout_height="wrap_content"
android:layout_width="match_parent"
layout="#layout/other_layout"/>
<android.support.design.widget.NavigationView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/navigation_view"
android:layout_gravity="start"
app:menu="#menu/drawer_menu"/>
</android.support.v4.widget.DrawerLayout>
Now add your other layouts to another layout file
other_layout.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:background="?attr/colorPrimaryDark"
android:minHeight="?attr/actionBarSize"
android:fitsSystemWindows="true"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<FrameLayout
android:id="#+id/mainfrag"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"

</FrameLayout>
</LinearLayout>

<fragment

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/main_layout" />
</FrameLayout>
</LinearLayout>
<android.support.design.widget.NavigationView

DrawerLayout Should only contain two child Views, first the main content and then the drawer view.
Creating a Navigation Drawer

How to add some space under the last item in a Navigation Drawer?

I have a Navigation Drawer that contains several items.
I added a button on the bottom of the Navigation Drawer.
The problem is that in small size screens the button covers the last item in the Drawer.
How can I add some space under the last item so the button won't cover anything?
activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>

</android.support.v4.widget.DrawerLayout>
activity_main_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu

<item
android:id="#+id/action_contact_us"
android:icon="#drawable/ic_contact_us"
android:title="#string/action_contact_us" />
<item
android:id="#+id/action_share"
android:icon="#drawable/ic_share_24dp"
android:title="#string/action_share" />
<item
android:id="#+id/action_rate_us"

android:title="#string/action_about_us" />
<item
android:id="#+id/action_settings"
android:icon="#drawable/ic_settings_24dp"
android:title="#string/action_settings" />
</group>
</menu>

I came up with an idea how to do it and it worked for me.
What I needed to do is to add one more Item to the Drawer and then disable it.
The code is:
<item
android:title=""
android:enabled="false" >
</item>
Very simple and easy!!!

May be you can try something like this
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
