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"

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: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:layout_height="match_parent" />
</LinearLayout>
</FrameLayout>
<!-- The navigation drawer -->

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"

</RelativeLayout>
</android.support.v4.widget.DrawerLayout>

Toolbar fills the whole screen

I'm new to the drawer layout and the use of fragments.
I used the tutorial on creating an activity with a DrawerLayout.
It gave me a nullpointer on getActionBar(), so I added a toolbar to the activity main and used getSupportActionBar() instead.
Now it looks like the toolbar fills the entire screen, because the title is in the middle of the screen and the background of the toolbar is on the whole screen too. Here is the xml code:
<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_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Toolbar -->
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF" />
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
I've tried replacing the layout_height with 56dp and i've tried making a seperate layout file with the toolbar in it and include it into this xml, but that didn't work.
Why is my Toolbar filling the entire screen?

A DrawerLayout expects 2 Views in it. You supply 3.
The first view is the "background". It is the content of your screen. The second view, the drawer, is supposed to animate in and out.
You supply 3 views. So your toolbar is "the content"—thus fullscreen, and your drawer is your actual content.
To fix your issue, try something like this:
<DrawerLayout>
<!-- The main content view -->
<LinearLayout>
<Toolbar/>
<FrameLayout
android:id="#+id/content_frame"/>
</LinearLayout>
<!-- The navigation drawer -->
<ListView/>
</DrawerLayout>

DrawerLayout will accept only two child views. Try to add the Toolbar in frame layout.
Or you can create like beliw.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The ActionBar -->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|enterAlways" />
<!-- The main content view -->
<FrameLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
app:headerLayout="#layout/layout_drawer_header"
app:itemTextColor="#000000"
app:menu="#menu/global">
</android.support.design.widget.NavigationView>

Hi, how can I put a Toolbar within this layout?
This layout for Navigation Drawer.
I've tried some code but still not working.
1. Under FrameLayout: Toolbar did not appear.
2. Below FrameLayout: Toolbar appear but content did not display.
3. Have DrawerLayout in a LinearLayout but my fragment seems didn't work well.
Thank you in advance.

Let me try to explain.
Android draws Views from top to down so; A-B-C- are you 3 respective Views in your DrawerLayout. now A being the Toolbar is drawn first with params width fit-to-the-overallwidth and height fit the content itself, B is drawn with width fit-to-the-overallwidth and height fit-to-the-overallheight, etc etc. that means your FrameLayout is drawn second in the drawing successions and on top of your Toolbar but since its covered you do not see that it is there, if you bring it below, your Toolbar is drawn second in succession hence you see it.
i hope you can deduct a solution from it now.

Have the toolbar in another layout which would be your main content view
<!-- The main content view -->
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:background="#color/octo"/>
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>

Try this :
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".main_drawer">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
>
<include
android:id="#+id/toolbar"
layout="#layout/tool_bar"
/>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:name="am.octogr.app.octocopy.NavigationDrawerFragment"
tools:layout="#layout/main_drawer_listview" />
<!-- Your Content -->
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
with a separate tool_bar.xml :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#color/octo"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
Don't forget to Initialize your Toolbar and set it as the ActionBar:
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
With a minSdkVersion of 14

Try this. It works fine for me.
Use this XML for your drawer activity.

you can find recent documentation about it on appbar.
They missed to include some code to make it work, here they are :
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
where R.menu.menu is your xml file in your project's res/menu/ directory. Paste above code on your activity which implement the Toolbar.

Remove shadow from Toolbar when Navigation Drawer is Open - Material Design support library

I am implementing Material Design into my app that has a navigation drawer. Amongst all the differing implementations of the Nav. Drawer and Toolbar with Material Design (see this post); I have chosen to keep the app feel similar to the ICS/Halo design and have the Nav Drawer slide out under the Toolbar. The problem is that the Toolbar dims with the shadow like the rest of the activity when the nav drawer is open. How would I keep the Toolbar from darkening? If you see the image in the post I linked above I am after #6, 3 or 5, but my looks more like #9 now.
Example (from post above):
What I'm after (no shadow on Toolbar):
What I currently get (Toolbar darkens when nav drawer is open):
Here is the code for my main activity's XML:
<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="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.funkhaus.navdrawer.app.MainActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- We use a Toolbar so that our drawer can be displayed
in front of the action bar; Added for Material Design -->
<android.support.v7.widget.Toolbar
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize" />
</FrameLayout>
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
android:fitsSystemWindows="true"
android:layout_gravity="start"
android:name="com.funkhaus.brewwerks.NavigationDrawerFragment" />
The notable part being that the <FrameLayout> whose ID is 'container' is where all my fragments are inflated, and its marginTop was set to the height of the Toolbar so its content would be below the Toolbar. Similarly, the Navigation Drawer fragment also has its marginTop set to the height of the Toolbar so it slides out below it.

Thanks to #alanv I fixed my issue.
My post above shows my activity_main.xml code; I simplified it to this, removing the Toolbar view and removing the marginTop formatting:
<android.support.v4.widget.DrawerLayout
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"
android:fitsSystemWindows="true"
tools:context="com.funkhaus.navdrawer.app.MainActivity">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<fragment android:id="#+id/navigation_drawer"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:layout_gravity="start"
android:name="com.funkhaus.brewwerks.NavigationDrawerFragment" />
</android.support.v4.widget.DrawerLayout>
I created a toolbar.xml, which I now setContentView() on in my main Activity that <include>'s the activity_main.xml above:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical">
<!-- We use a Toolbar so that our drawer can be displayed
in front of the action bar; Added for Material Design -->
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<include android:id="#+id/drawer_layout" layout="#layout/activity_main" />
</LinearLayout>
Finally, in my Activity's onCreate() I setContentView() on the toolbar.xml:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.toolbar);
// Rest of code here....

You do it in the same xml like this, This is for underlying toolbar navigation like play store app design
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"

</android.support.v4.widget.DrawerLayout>
</FrameLayout>

How do I make DrawerLayout to display below the Toolbar?

How to make the drawer layout be below the actionbar/toolbar? I'm using v7:21 app compat library with the new ToolBar view.
Examples that I see looks like
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/my_drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- drawer view -->
<LinearLayout
android:layout_width="304dp"
android:layout_height="match_parent"
android:layout_gravity="left|start">
<!-- drawer content -->
</LinearLayout>
<!-- normal content view -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The toolbar -->
<android.support.v7.widget.Toolbar
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<!-- The rest of content view -->
</LinearLayout>
But then the toolbar will be hidden by the drawer, which makes an animated hamburger icon (like v7.ActionBarDrawerToggle) useless since it will not be visible below the drawer, but I do want to use the new ToolBar view to support Material theme better.
So how to accomplish that? Is it possible to have DrawerLayout as a non top-level view?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The toolbar -->
<android.support.v7.widget.Toolbar
android:id="#+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/my_drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- drawer view -->
<LinearLayout
android:layout_width="304dp"
android:layout_height="match_parent"
android:layout_gravity="left|start">
<!-- drawer content -->
</LinearLayout>
<!-- normal content view -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The rest of content view -->
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>

i don't think you can when using custom toolbar
but a work around would be to set a top_margin to drawer.
(the same thing on google play store!)
<!-- drawer view -->
<LinearLayout
android:layout_marginTop="?attr/actionBarSize"
...
if you found a better solution tell me too ;)

Change Your drawer layout style like as below
RelativeLayout
----Toolbar
----DrawerLayout
---ContentView
---DrawerList

My solution: generate template with Android Studio 2.1.2, drawer template:
Only need three changes: set margin top in view NavigationView and delete overloap statusbar in style.xml
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
android:fitsSystemWindows="false"
layout main.xml set margin top get size actionbar value
android:layout_marginTop="?attr/actionBarSize"

I had issues getting this to work, and it finally displayed properly. Here is the layout I used:
<LinearLayout...[add your namespaces, etc]
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar [your custom toolbar] />
<android.support.v4.widget.DrawerLayout [your drawer layout] />
<LinearLayout>
[content here]
</LinearLayout>
<android.support.design.widget.NavigationView />
</LinearLayout>
Be careful moving the design widgets around, if one is under the wrong root tag, you'll get a
"no layout_gravity_left"
exception.

I have found a simpler solution:
Set the DrawerLayout and NavigationView attribute:
android:fitsSystemWindows="false"
and then give marginTop to navigation view as
"?actionBarSize"
maybe your statusbar background will become transparent in that case in styles.xml add
<item name="android:statusBarColor">#color/colorPrimaryDark</item>
attribute to get back the normal color or any other color you want...

Here is the Kotlin solution:
In the layout file containing your DrawerLayout...
Add android:keepScreenOn="true" to the DrawerLayout
Add android:layout_marginTop="?android:attr/actionBarSize" to the NavigationView
The full XML piece should look like this:
<com.mullr.neurd.Miscellaneous.CustomDrawerLayout
android:id="#+id/clipped_drawer_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:keepScreenOn="true"
tools:openDrawer="start"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<com.google.android.material.navigation.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:layout_marginTop="?android:attr/actionBarSize"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</com.mullr.neurd.Miscellaneous.CustomDrawerLayout>
That should do it (ignore my clipped nav drawer).
