Subcategory Navigation Box Menu

I have a navigation box in my application using the DrawerLayout and NavigationView class. Right now I have my mailbox showing all my categories, inflating an XML menu file. How can I get it so that some of these categories are separated by subtitles and separators?

You can do this very easily by simply modifying the existing xml menu file.

Your code will look something like this:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/group1" android:title="title1"> <menu> <item android:title="item1" /> <item android:title="item2" /> </menu> </item> <item android:id="@+id/group2" android:title="title2"> <menu> <item android:title="item1" /> <item android:title="item2" /> <item android:title="item3" /> </menu> </item> </menu>

All you do is specify a new menu inside each element and provide the parent element with a title!

I think this code will help you set up a separator between your items and items. Check 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" tools:context=".MainActivity"> <group android:id="@+id/grp1" android:checkableBehavior="single" > <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" android:checkableBehavior="single" > <item android:id="@+id/navigation_item_2" android:icon="@drawable/ic_home" android:title="@string/navigation_item_2" /> </group>

Happy coding
