How to draw a line between menu item in navigation drawer

Question

I want to highlight navigation items like this:

But my current menu looks like this:

My menu.xml is

<?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">
    <group android:checkableBehavior="single">
        <item android:id="@+id/home"
            android:title="Home"
            android:icon="@drawable/ic_action_home_page"/></group>
    <group android:checkableBehavior="single">
        <item android:id="@+id/p_profile"
            android:title="Payment Profile"
            android:icon="@drawable/ic_action_payment_profile"/></group>
    <group android:checkableBehavior="single">
        <item android:id="@+id/p_history"
            android:title="Payment history"
            android:icon="@drawable/ic_action_payment_history"/></group>
    <group android:checkableBehavior="single">
        <item android:id="@+id/m_cards"
            android:title="My cards"
            android:icon="@drawable/ic_action_my_card"/></group>
        <group android:checkableBehavior="single">
            <item android:id="@+id/menu_friends"
                android:title="Friends"
                android:icon="@drawable/search_people"/></group>

    <group android:checkableBehavior="single">
        <item android:id="@+id/notification"
            android:title="Notification"
            android:icon="@drawable/ic_action_notification"/></group>
    <group android:checkableBehavior="single">
        <item android:id="@+id/about"
            android:title="About"
            android:icon="@drawable/ic_action_about_us"/></group>

    </group>
</menu>

How can I create the above highlight effect?

Answer 1

Give each group a unique id like this:

<group android:checkableBehavior="single"
android:id="@+id/group1">

It'll draw those lines for you between any two groups.

EDIT: Since the line is now showing but it's black on the black background, refer to this question to see how to change the color of the divider.
