How to integrate expandable list view inside navigation drawer?

I created a project for my expandable list view. Also, in my other main project, I created a navigation drawer. Everything works fine as it is own. Unfortunately, I want to show this expandable list view inside my navigation drawer and I don't know where to start. I feel like there should be minor additions (already have adapter and stuff) but seriously I have no idea about how to implement the layout inside the drawer. I searched about this topic and all examples and answers are not so clear to me.
Can you please point me to the right direction?

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.

Make a custom Layout to use custom navigation view as given below in (layout_nav_bar.xml):-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/color_white"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<include
android:id="#+id/nav_header"
layout="#layout/nav_header_main"
/>
<ExpandableListView
android:id="#+id/expandableListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none"
android:overScrollMode="never"
android:background="#android:color/white"
android:divider="#null"
android:groupIndicator="#null" />
</LinearLayout>
Add this to your DrawerLayout
<include
android:id="#+id/nav_view"
layout="#layout/layout_nav_bar"
android:layout_gravity="start"
android:fitsSystemWindows="true"
android:layout_height="match_parent"
android:layout_width="match_parent"/>

How can i create Grid like view using Menu Item in android NavigationView

I have an android application with navigation drawer. It has list of menu like Gmail application as follows
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:openDrawer="left">
<include
layout="#layout/app_bar_dashboard"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header_dashboard"
app:menu="#menu/activity_dashboard_drawer" />
I want that menu list to be a grid like view. how can i achieve that?

Instead of NavigationView you can use your custom layout. create a layout file with Grid design and include it here in this file instead of NavigationView
<LinearLayout
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
android:orientation="vertical">
<include layout="#layout/layout_grid_left" />
</LinearLayout>
and create layout_grid_left with your left View

How to Add scroable footer layout in navigationview tag in drawer in android?

This is drawer layout part.
<?xml version="1.0" encoding="utf-8"?>
<include layout="#layout/main_fragment"></include>
<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"
app:headerLayout="#layout/nav_header_dashboard"
app:menu="#menu/activity_dashboard_drawer">

android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="bottom">
<include layout="#layout/nav_header_dashboard"/>
</LinearLayout>
</android.support.design.widget.NavigationView>
Here i have add menu attribute and header layout attribute.
But i am not able to add unfixed footer layout.

My emulator shows just Listview on entire screen. even its width is limited to 240dp

I am using drawer layout and Listview is using as drawer.
My emulator just showing Listview as width set to match parent even it's set to 240dp.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/drawer Layout"
android:background="#000000">
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:id="#+id/drawerList"
android:background="#color/colorAccent"/>
<FrameLayout
android:layout_width="250dp"
android:layout_height="match_parent"
android:id="#+id/fragmentContainer"
android:background="#ffffff"
android:choiceMode="singleChoice"
android:dividerHeight="0dp"
android:divider="#android:color/transparent"/>
</android.support.v4.widget.DrawerLayout>

Drawer layouts are usually hidden outside of the screen until you open them. Try opening the drawer by swiping from the side.

You must use NavigationView inside DrawerLayout and limit width in NavigationView.
Example layout structure is like that , there is 2 different usage of NavigationView :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- you can add extra views in DrawerLayout -->
<include layout="#layout/content_home"/>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:layout_gravity="start"
app:menu="#menu/homepage_leftdrawer"/>
<!-- you can use listview, recyclerview etc in navigationview -->
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view2"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:fitsSystemWindows="false"
app:headerLayout="#layout/homepage_right_header"
android:layout_gravity="end">
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:choiceMode="singleChoice"
android:dividerHeight="1dp"
android:layout_marginTop="80dp" />
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>

Android hide NavigationView header

I am working on an android app and it requires DrawerLayout below the ToolBar. I've achieved that but NavigationView's header i.e Status Bar 24dp is visible even after removing the header.
Is there a way to remove that?
XML file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<include
layout="#layout/app_bar_home"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<android.support.v4.widget.DrawerLayout
android:layout_marginTop="?android:attr/actionBarSize"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.design.widget.NavigationView
android:paddingBottom="0dp"
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#null"
app:menu="#menu/activity_home_drawer"/>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>

try this one :
View headerView = navigationView.inflateHeaderView(R.layout.nav_header_home);
headerView.setVisibility(View.GONE);
and remove the line app:headerLayout="#null" from your xml.

Also try like this,
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:background="#color/list_background"/>

Probably because the height is not enough. Why don't you use wrap_content with layout="#layout/app_bar_home" and add android:layout_below to your DrawerLayout?
Or to keep it simple, you can also use LinearLayout in this case. It would be easier:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<include
layout="#layout/app_bar_home"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.design.widget.NavigationView
android:paddingBottom="0dp"
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#null"
app:menu="#menu/activity_home_drawer"/>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>

Remove app:headerLayout="#null" from your navigationview.
inflate your headerlayout from onCreate() like this, and then set the visiblity gone.
View headerView= LayoutInflater.from(this).inflate(R.layout.drawer_header, null);
navigationView.addHeaderView(headerView);
navigationView.getHeaderView(0).setVisibility(View.GONE);

Define groups in menu and then hide group using:
navigationView.getMenu().setGroupVisible(groupPosition, false);
Also, remove headerLayout attribue.
