ImageView is not showing in Drawer?

I have simple DrawerLayout which contains some main content (they all display nicely), a navigation drawer which is only a RelativeLayout (id: drawerPane) and ListView (which I filled with BaseAdapter).
My goal is to insert some image above navigation items in the drawer. I tried inserting that image (from within drawerPane of course) by encapsulating it in LinearLayout, RelativeLayout, placing it on its own, but image is not showing.
How to insert that image in Drawer above navigation items?
Here is XML with short comments.

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:

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

Hide Toolbar and footer when scrolling up

I want to use the CoordinatorLayout in one of my activities.
The layout of the activity contains a Toolbar in the top, a RecyclerView in the middle, and a RelativeLayout at the bottom (the footer).
I would like to hide the Toolbar and the footer when the user swipes up the RecyclerView.
What I achieved so far:
When I swipe up, the Toolbar hides, but the footer (which was hidden before) reappears. I want the Toolbar and footer to be linked somehow, so that they hide at the same time when the user swipes.
I've heard about Behaviors but I don't know how to create them (I'm just using the default one).
My activity layout:
<android.support.v4.widget.DrawerLayout

Relative layout always seems to work for only drawer layout or frame layout, both child doesn't work together

I have a relative layout in which i have two child .one is drawer layout and the other is a frame layout in which i have used a fragment .The problem is when i keep drawer layout in the top and the frame layout in the bottom,drawer layout doesn't work and if do the opposite,frame layout doesn't
this is my relative layout
<RelativeLayout 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">
<include
android:id="#+id/toolbar_actionbar"
layout="#layout/mtoolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar_actionbar">
<fragment
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="com.example.rohit.newmastervocab.FloatingFragment"
android:id="#+id/fragment2"
android:layout_alignParentStart="true"
tools:layout="#layout/fragmentfloating"
android:layout_alignTop="#+id/drawer"
android:layout_gravity="center_horizontal|bottom" />
</FrameLayout>
<android.support.v4.widget.DrawerLayout android:id="#+id/drawer1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:layout_below="#+id/toolbar_actionbar"
android:layout_alignParentBottom="true">
<ListView
android:id="#+id/drawerlist1"
android:layout_width="240dp"
android:layout_height="match_parent"
android:entries="#array/navigation_items"
android:background="#F3F6C8"
android:layout_gravity="start">
</ListView>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>

Mike M. is absolutely right: you need to keep FrameLayout as one of the Children of DrawerLayout.
I've updated your XML a bit, take a look:
<?xml version="1.0" encoding="utf-8"?>
<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:openDrawer="start">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_actionbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<FrameLayout
android:layout_below="#+id/toolbar_actionbar"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:layout_gravity="center_horizontal|bottom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="com.example.rohit.newmastervocab.FloatingFragment"
android:id="#+id/fragment2"/>
</FrameLayout>
</RelativeLayout>
<ListView
android:id="#+id/drawerlist1"
android:layout_width="240dp"
android:layout_height="match_parent"
android:entries="#array/navigation_items"
android:background="#F3F6C8"
android:fitsSystemWindows="true"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
Now drawer works just as expected and Fragment is stick to the bottom|center of the screen.

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"
