How do I add more spacing per item in my NavigationDrawer?

I can't seem to find a solution on how to add even more space between each item of my navigation drawer. Here is the image of what it looks like now.
.
I want to my items in my navigation drawer to have even more space in between. I tried android:paddingTop and android:layout_marginTop in my NavigationView of my activity.xml but it doesn't seem to work. How can I add more space between Items?
To help here is my code for my activity.xml
<?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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".Location.Location"
android:id="#+id/drawer_layout"
tools:openDrawer="start"
>
<com.google.android.material.navigation.NavigationView
android:id="#+id/drawerNavigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/navigation_drawer_header"
app:menu="#menu/navigation_drawer_menu"
android:fitsSystemWindows="true"
app:insetForeground="#android:color/transparent">
</com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
It might help, here is my Menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<group android:checkableBehavior="single">
<item
android:id="#+id/homeNavigationDrawer"
android:title="Home"
android:icon="#drawable/icon_home_nav_drawer"
/>
<item
android:id="#+id/profileNavigationDrawer"
android:title="Profile"
android:icon="#drawable/icon_profile_nav_drawer"
/>
<item
android:id="#+id/topicsNavigationDrawer"
android:title="Topics"
android:icon="#drawable/icon_latest_news_black"
/>
<item
android:id="#+id/settingsNavigationDrawer"
android:title="Settings"
android:icon="#drawable/icon_settings"
/>
</group>
</menu>

For more space between each item You can apply following Theme in your styles.xml for Navigation Drawer
style name="NavigationTheme" parent="AppTheme">
<item name="android:textSize">16sp</item>
<item name="android:layout_marginBottom">8dp</item>
</style>
Apply this theme in Navigation Drawer
android:theme="#style/NavigationTheme"

xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView

<item
android:id="#+id/menu_end_session"

</menu>

first: You can put your device in RTL mode, go to develop settings (Force RTL layout direction).
After doing this all the layouts will mirror correctly.
If you don't want to change the whole device into RTL use this code in onCreate method of mainactivity before super and before you inflate the content view
window.decorView.layoutDirection = View.LAYOUT_DIRECTION_RTL

You need to use a custom layout for NavigationView.
According to this: http://www.kamilslesinski.com/home/navigation-drawer-customising-navigationview-items you can override the layout by copying original file and customizing it, or you can add a reference to your custom layout, like that:

in refs.xml.

Android Change Navigation View Menu Background

In my app i want to change the navigation view menu background, but i dont know how to do this. All posts i have watched explains how to change each menu item background, but all i need is to change the entire background of the menu.
This is what i want to change, the entire white background:
activity_main_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item android:id="#+id/nav_camara" android:icon="#android:drawable/ic_menu_camera"
android:title="Import" />
<item android:id="#+id/nav_gallery" android:icon="#android:drawable/ic_menu_gallery"
android:title="Gallery" />
<item android:id="#+id/nav_slideshow" android:icon="#android:drawable/ic_menu_slideshow"
android:title="Slideshow" />
<item android:id="#+id/nav_manage" android:icon="#android:drawable/ic_menu_manage"
android:title="Tools" />
</group>
<item android:title="Communicate">
<menu>
<item android:id="#+id/nav_share" android:icon="#android:drawable/ic_menu_share"
android:title="Share" />
<item android:id="#+id/nav_send" android:icon="#android:drawable/ic_menu_send"
android:title="Send" />
</menu>
</item>
</menu>
Is there anyway to change the white background from the activity_main_drawer layout?
activity_main.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>
Thanks in advance.

You can set background to your NavigationView to change its color like below (set to app_white ) & for header set any color as a background of drawer_header_layout.
<android.support.design.widget.NavigationView
android:id="#+id/adcl_navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/app_white"
app:headerLayout="#layout/drawer_header_layout"
app:itemIconTint="#color/app_secondary_text"
app:itemTextColor="#color/app_secondary_text"
app:menu="#menu/menu_drawer"
app:theme="#style/ThemeOverlay.AppCompat.Light" />

just add android:background="#color/yourColor" to the <android.support.design.widget.NavigationView.

See navigation drawer preview

I'm designing a native navigation drawer in Android Studio.
I can't see the drawer in my preview because it is sitting left of the activity, out of range of the preview.
For now I'm using a testlayout.xml file to see my changes, but a lot of times I forget to copy paste them into the right activity.
Is there a way to preview the drawer layout?

If you want to be able to preview the drawer layout / navigation bar
If you are following the tutorial at https://developer.android.com/training/implementing-navigation/nav-drawer.html
You can put your listview for the nav drawer in a different xml file in the /layout folder, then include it in the drawer layout xml. Means you can edit it in the drawer_layout file and be able to see it properly
layout/drawer_layout
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/left_drawer"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#color/nav_drawer_background_color"/>
Then in the navbar
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- The navigation drawer -->
<include
android:id="#+id/listView"
layout="#layout/drawer_layout"/>
</android.support.v4.widget.DrawerLayout>

To see NavigationView preview add tools namespace to your drawer layout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
then add attribute tools:openDrawer equal to gravity of layout_gravity value of your Navigation view, for example
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:openDrawer="left">
<android.support.design.widget.NavigationView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="left"
app:headerLayout="#layout/navigation_header_main"
app:itemTextAppearance="#style/NavigationItemStyleLight"
app:menu="#menu/navigation_main_menu"/>
</android.support.v4.widget.DrawerLayout>

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_camera"
android:icon="#drawable/ic_menu_camera"
android:title="Import" />
<item
android:id="#+id/nav_gallery"
android:icon="#drawable/ic_menu_gallery"
android:title="Gallery" />
<item
android:id="#+id/nav_slideshow"
android:icon="#drawable/ic_menu_slideshow"
android:title="Slideshow" />
<item
android:id="#+id/nav_manage"
android:icon="#drawable/ic_menu_manage"
android:title="Tools" />
</group>
<item android:title="Communicate">
<menu>
<item
android:id="#+id/nav_share"
android:icon="#drawable/ic_menu_share"
android:title="Share" />
<item
android:id="#+id/nav_send"
android:icon="#drawable/ic_menu_send"
android:title="Send" />
</menu>
</item>
Just Add
tools:showIn="navigation_view"

You can use NavigationView to get its preview on AndroidStudio, Its much better and easier to implement then the old NavigationDrawer.
activity_main.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/prof_app_bar"
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:itemTextColor="#color/text_head_color"
app:itemIconTint="#null"
app:headerLayout="#layout/nav_header_main2"
app:menu="#menu/professional_menu" />
</android.support.v4.widget.DrawerLayout>
Define the menu in navigationmenu.xml place it in menu resource folder:-
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single"
android:id="#+id/top_menu">
<item
android:id="#+id/pnav_setting"
android:icon="#drawable/accountsettings"
android:title="#string/paccount_settingss" />
<item
android:id="#+id/pnav_expertise"
android:icon="#drawable/professional"
android:title="#string/pexpertise" />
<item
android:id="#+id/pnav_comu"
android:icon="#drawable/communication"
android:title="#string/pcomunication" />
<item
android:id="#+id/pnav_change_pass"
android:icon="#drawable/changepasswd"
android:title="#string/pchange_pass" />
<item
android:id="#+id/pnav_change_lang"
android:icon="#drawable/changelang"
android:title="#string/pchange_lang"
android:visible="true"/>
</group>
<group android:checkableBehavior="single"
android:id="#+id/middle_menu">
<item
android:id="#+id/pnav_about_us"
android:icon="#drawable/aboutus"
android:title="#string/about_us" />
<item
android:id="#+id/pnav_feedback"
android:icon="#drawable/feedback"
android:title="#string/feedback"
android:visible="false"/>
<item
android:id="#+id/nav_privacy_policy"
android:icon="#drawable/privacy"
android:title="#string/privacy_policy" />
<item
android:id="#+id/pnav_faq"
android:icon="#drawable/faq"
android:visible="false"
android:title="#string/faq" />
<item
android:id="#+id/pnav_contact_us"
android:icon="#drawable/contactus"
android:title="#string/contact_us" />
</group>
<group android:checkableBehavior="single"
android:id="#+id/bottom_menu">
<item
android:id="#+id/pnav_sign_out"
android:icon="#drawable/signout"
android:title="#string/sign_out" />
</group>
</menu>
And, for getting click events use this:-
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(yourItemclickListener);
