Android: 2 or more ExpandableListView inside Navigation Drawer
Finally i have got it!
This is the code I created to get an ExpandableListView with section titles.
Now it's I can easily create three xml custom layouts for titles, groups and childrens.
It work for me, but I accept any code improvements to optimize memory usage, speed and so on.

how to create an expandable listView inside navigation drawer?
You can create an ExpandableListView and use it as your NavigationView. An example of xml result:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
tools:context=".MainActivity">
<include
layout="@layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!-- This DrawerLayout has two children at the root -->
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- This LinearLayout represents the contents of the screen -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The main content view where fragments are loaded -->
<FrameLayout
android:id="@+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- The navigation drawer that comes from the left -->
<!-- Note that `android:layout_gravity` needs to be set to 'start' -->
<ExpandableListView
android:id="@+id/lvExp"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
You can find an example of using an ExpandableListView here
How to integrate expandable list view inside navigation drawer?
You can do it by adding ExpandableListView in NavigationDrawer like below:
You can create it using custom ListView.
See the code below activity_navigation_view.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<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">
<ExpandableListView
android:id="@+id/navigationmenu"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginTop="192dp"
android:background="@android:color/white">
</ExpandableListView>
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
And Simply create adapter for it and use it like a normal ExpandableListView.
implement expandablelistview in navigation drawer activity made by android studio
You have to do that the same way as you would add headings in any ListView using Adapter to return heading rows as well as detail rows.

- How To Make Material Design Navigation Drawer With Header View
Android Navigation Drawer ExpandableListView
If you want to achieve above behavior to your NavigationDrawer you can follow below steps:
1) You have to add Expandable listview to your NavigationView.
2) Create Header View
3) Create Child View.
4) Extend BaseExpandableListAdapter
5) Set Adapter in MainActivity
There are few solutions available. You can follow this tutorial or this. For basic knowledge about creating Navigation drawer, you can go here. I got helped by these tutorials and they are very easy to apply.
Hope this helps.
