Drawer layout setBackgroundColor does not work

I need to set the background color of my DrawerLayout at runtime. Here's what I'm doing:
DrawerLayout drawerLayout = findViewById(R.id.drawer_layout);
drawerLayout.setBackgroundColor(Color.parseColor("#ffffff"));
I'm not really going to set it to a hard coded value, that's just for illustration. This seems to have no effect - the background stays a dark gray color that I think is picked up from a style somewhere. I can set the background color of the ExpandableListView inside the DrawerLayout, but I can't get that to fill the vertical space, so some of the background is the correct color and the empty space is the wrong color.
Setting the background color of the ExpandableListView in XML works, but I need to be able to change it at run time. If I don't set the ListView color in XML, the ListView will not fill the vertical space as I want it to do. It just cuts off after displaying all the items. I've tried setting both the drawer layout and list background in Java, and the closest I can come to having any effect is the empty space below the list items changes color. I cannot get the background of the actual list to change. Any suggestions?
Layout XML:
<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"
android:orientation="vertical"
tools:context=".activities.MainActivity">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/primary"

<!-- The navigation drawer -->
<ExpandableListView

android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:groupIndicator="#null" />
</android.support.v4.widget.DrawerLayout>
Screen shot:

I think you need to set background for your NavigationView instead of DrawerLayout.
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white" //set background here
app:itemBackground="#android:color/transparent"
app:menu="#menu/menu_navigation"/>
If you use ExpandableListView inside DrawerLayout. I think you should put the ExpandableListView inside a RelativeLayout. Like this:
<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"
android:orientation="vertical"
tools:context=".activities.MainActivity">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/primary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ToolBarStyle" />
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</FrameLayout>
<!-- The navigation drawer -->
<RelativeLayout
android:id="#+id/drawer_container"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#drawable/background"> //set background here
<ExpandableListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/drawer_background"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:groupIndicator="#null" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>

ExapandableListview inside Navigation Drawer

How to use ExapandableListview inside navigation drawer like Snapdeal
What I want is this
Result so far is this

Try below XML code that works fine
<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"
<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>
</LinearLayout>

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>

Adding a Fixed/Static Header to a Navigation DrawerLayout

Like many apps, I use the DrawerLayout code like this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".MainActivity">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="right"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#FFFFFF" />
</android.support.v4.widget.DrawerLayout>
I have some user information above the ListView so I use the addHeaderView(). However, this scrolls with the list. I would like the list to appear that it is scrolling underneath it and the header stays fixed at the top.
Is this possible? I have tried by wrapping the ListView inside a LinearLayout with the header code inside that layout as well. This completely broke the app. Are there any other ways? I have actually seen Google do this in at least one of their apps (youtube).

Wrapping your List in some kind of layout is the way to go. Maybe you just missed something. Try this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".MainActivity">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- The navigation drawer -->
<LinearLayout
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="right">
<!--SOME HEADER-->
<View
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#FFFFFF" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>

set navigation drawer above view pager dynamically

I just want to put my navigation drawer on the top of my app, right after the navigation drawer my sliding menu should be displayed. So I figured out to do this with "android:layout_marginTop="xdp"/>". When I don't do this my nav drawer and the sliding tabs will overlap each other.
So my question is how can I do this dynamically with xml e.g. how can I get the height of the navdrawer to set the correct size for the marginTop?
Here is my xml-layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.starpedia.marvin.swc_pedia.FragmentNavigationDrawer
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<!-- The ActionBar -->
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!-- The main content view -->
<FrameLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/lvDrawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:paddingTop="24dp"
android:divider="#android:color/darker_gray"
android:dividerHeight="0dp"
android:background="#android:color/background_light" />
<com.starpedia.marvin.swc_pedia.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"/>
</com.starpedia.marvin.swc_pedia.FragmentNavigationDrawer>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white"/>
</LinearLayout>
and a picture of the current screen displayed.
Thanks for your help in advance.
