Answer 1

Below code works fine for me
my nav view:

<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"
    android:background="@color/nav.background"
    app:menu="@menu/menu_drawer"
    app:itemBackground="@drawable/nav_item_background"
    app:itemTextColor="@drawable/nav_item_text"/>

drawable/nav_item_background.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_pressed="true" android:drawable="@color/nav.item.background" />
  <item android:state_checked="true" android:drawable="@color/nav.item.background" />
  <item android:state_focused="true" android:drawable="@color/nav.item.background" />
  <item android:state_activated="true" android:drawable="@color/nav.item.background" />
  <item android:drawable="@color/nav.item.background.default" />
</selector>

drawable/nav_item_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="@android:color/white" android:state_checked="true" />
  <item android:color="#bdbdbd" />
</selector>

Answer 2

@HaloMediaz and @HemantShori To keep the background of the selected item in a selected state,

use android:state_checked="true" instead of android:state_pressed="true" in the color state resource.

So your activated color state resource should look like this:

activated_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@color/White" />
    <item android:state_focused="true" android:drawable="@color/White" />
    <item android:state_activated="true" android:drawable="@color/White" />
    <item android:drawable="@android:color/transparent" />
</selector>

Answer 3

To have the background display on your selected item you need to add

 android:checkable="true"

on every item of your menu.xml items, then set :

app:itemBackground="@drawable/nav_view_item_background"

on your NavigationView and finally:

drawable/nav_view_item_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/primary" android:state_checked="true" />
    <item android:drawable="@android:color/transparent" />
</selector>

Answer 4

You don't set the drawable for the background of a Navigation View item in your styles.xml file. Open up your XML layout file containing your Navigation View widget, and add the following line to the widget's attributes:

app:itemBackground="@drawable/activated_background.xml"

If you're having trouble with the "app" pointer, add the following line in as well:

xmlns:app="http://schemas.android.com/apk/res-auto"

Note that this only changes the colour of the background of a selected list item. If you'd like the icon and text colour to change as well, use the app:itemTextColor attribute instead.

Answer 5

You must use android:background="color" for back color of navigation menu like:

<android.support.design.widget.NavigationView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:id="@+id/shitstuff"
        app:itemTextColor="@color/black"
        app:menu="@menu/drawermenu"
        android:background="@color/colorAccent"
        android:layout_marginTop="-24dp"
        />

and for items color use itemTextColor="color"
