`NavigationView` is not meant to have arbitrary `View`s added to it. If you're not using the `NavigationView` for its specific functionalities, then remove it, and make the `LinearLayout` the drawer, by setting `android:layout_gravity="start"` on it, and giving it a definite `layout_width`, e.g., `240dp`. — Mike M., Feb 14 '18 at 08:04
remove the `LinearLayout` inside the `NavigationView`. Just `` the menu layout inside it. — Ishita Sinha, Feb 14 '18 at 08:07
@IshitaSinha That's still adding arbitrary `View`s to the `NavigationView`, which is not how that's meant to be used. If the `NavigationView` is not actually being used for what it does, it should just be removed. — Mike M., Feb 14 '18 at 08:15
@Mike M with reference to this https://stackoverflow.com/questions/30626324/navigationview-and-custom-layout. i wanted to add a custom menu and use navigation menu just like this .. and my requirement were also a full screen navigation view — Farrukh khalid, Feb 14 '18 at 08:18
Yeah, don't do that. That's a terrible answer, and I can't believe it has that many upvotes. `NavigationView` is meant for a very specific design. It's not supposed to be a general-purpose container for other `View`s. You're not using it for what it does, so just remove it, and make the `LinearLayout` the drawer. A drawer does not have to be a `NavigationView`. It can be pretty much any `View`, like your `LinearLayout`, or even just the ``, depending on what's in that. — Mike M., Feb 14 '18 at 08:21
@Mike M. Thanks it worked ! but now a different issue arises the lay out that i added is not showing background colors that its supposed to show .. — Farrukh khalid, Feb 14 '18 at 08:33
I'm not sure what you mean. You can set the `background` on the `LinearLayout`, if that's what you're talking about. I believe the default for `NavigationView` is `android:background="?android:attr/windowBackground"`, which you could add to the `LinearLayout` yourself. — Mike M., Feb 14 '18 at 08:42

You have to include your Nav. Drawer menu items like this , Check the below xml code as references :

Here included as app:menu="@menu/nav_drawer_items"

You can take the reference of this question with solution : Align custom view to left of navigation drawer

 <?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">

    <android.support.design.widget.NavigationView
        android:id="@+id/nav1"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/nav_drawer_items"
        app:itemBackground="@color/app_bg_color"
        app:itemIconTint="@color/text_white"
        app:itemTextColor="@color/text_white"
        android:background="@color/bottom_navigation_color"
        android:fitsSystemWindows="true"
        android:theme="@style/NavigationView" />
</android.support.v4.widget.DrawerLayout>
