                android:id="@+id/action_addtag"
                android:title="@string/add_hashtag_string"
                app:showAsAction="never" />
            <item
                android:id="@+id/action_block_list"
                android:title="Block"
                app:showAsAction="never" />
            <item
                android:id="@+id/action_report_list"
                android:title="Report"
                app:showAsAction="never" />
<!--group2-->
            <item
                android:id="@+id/terms"
                android:title="Terms"
                app:showAsAction="never" />
            <item
                android:id="@+id/feedback"
                android:title="FeedBack"
                app:showAsAction="never" />
<!--group3-->
            <item
                android:id="@+id/action_setting"
                android:title="Setting"
                app:showAsAction="never" />
    </menu>

Solution

All you need to do is define a group with an unique ID, I have checked the implementation if group has different id's it will create a divider.

Example menu, creating the separator:

<menu 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"
tools:context=".MainActivity">

<group android:id="@+id/grp1">
    <item
        android:id="@+id/navigation_item_1"
        android:checked="true"
        android:icon="@drawable/ic_home"
        android:title="@string/navigation_item_1" />
</group>

<group android:id="@+id/grp2">
    <item
        android:id="@+id/navigation_item_2"
        android:icon="@drawable/ic_home"
        android:title="@string/navigation_item_2" />
</group>

hope this helps

UPDATE

for menu item may be you can use this

    <menu 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">
    <item
        android:id="@+id/action_cart"
        android:title="cart"
        android:actionLayout="@layout/cart_update_count"
        android:icon="@drawable/shape_notification"
        app:showAsAction="always"/>
</menu>

and actionLayout file will be

 <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:id="@+id/divider"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/divider"/>

    <TextView
        android:id="@android:id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?android:attr/selectableItemBackground"
        android:gravity="center_vertical"          
        android:textAppearance="?attr/textAppearanceListItemSmall"/>

</LinearLayout>
