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.

Trying to add a menu to ToolBar

Trying to add a menu to my toolbar, however the code supposedly required to do that is showing errors:
Here's my other code:
res/menu/home_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/settings"
android:title="#string/settings" />
<item
android:id="#+id/dark_theme"
android:title="#string/dark_theme" />
</menu>
Here's the layout with the Toolbar I want to add the menu to:
res/layout/activity_home.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorVeryDark"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar" />
</LinearLayout>
Any idea how I can add my menu to the toolbar?

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:
styles.xml
<resources xmlns:android="http://schemas.android.com/apk/res/android">

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:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/toolbar"
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"
tools:layout="#layout/main_layout" />
</FrameLayout>
</LinearLayout>

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

Onclick highlight my list row doesn't working

Hello friends i have tried many different ways to highlight my listview but nothing works for me. i want to highlight my customlist view when i click on that and than open a new activity.
here is my xml file list_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Selector style for listrow -->
<item
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/gradient_bg" />
<item android:state_pressed="true"
android:drawable="#drawable/gradient_bg_hover" />
<item android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/gradient_bg_hover" />
</selector>
here is my gradient_bg_hover.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!-- Gradient BgColor for listrow Selected -->
<gradient
android:startColor="#18d7e5"
android:centerColor="#16cedb"
android:endColor="#09adb9"
android:angle="270" />
</shape>
And gradient_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

and my _activity_setup.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:divider="#b5b5b5"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector" />
</LinearLayout>
help me

Just remove the list-selector from your listview and instead, set the background for your item view:
Your listview:
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#b5b5b5"
android:dividerHeight="1dp"
android:listSelector="#null" />
Your item view (for example):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/list_selector" >
</LinearLayout>
Hope this helps.
