android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/header"
app:menu="@menu/drawer" />
</android.support.v4.widget.DrawerLayout>
header.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="190dp"
android:background="@drawable/background_material"
android:orientation="vertical"

<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"

</RelativeLayout>
drawer_menu_items.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/inbox"

android:title="My Places" />
</group>
</menu>
How can I only scroll the menu item not the header... I've attached some pictures too...

You should be able to place your header outside of the NavigationView, like so:
<?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"
<!-- nav drawer -->
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
>
<!-- header -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="190dp"
android:background="@drawable/background_material"
android:orientation="vertical"
>
<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/profile_image"
android:layout_width="76dp"
android:layout_height="76dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:layout_marginLeft="24dp"
android:layout_marginStart="24dp"
android:src="@mipmap/ic_launcher"
app:border_color="#FF000000" />
</RelativeLayout>
<!-- menu -->
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="0px"
android:layout_weight="1"
android:layout_gravity="start"
app:menu="@menu/drawer" />
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
Note: I've added a FrameLayout to encapsulate everything in a single view for the DrawerLayout, adjusted the NavigationView's height to automatically use the available space below your header, and have removed the headerLayout attribute.

I know its Too old Question but its too easy!
<android.support.design.widget.NavigationView
android:id="@+id/navigationview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/header_drawer"
app:menu="@menu/item_drawer">
</android.support.design.widget.NavigationView>
Add the following code to the NavigationView (<include layout="@layout/header_drawer"/>)
<android.support.design.widget.NavigationView
android:id="@+id/navigationview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/header_drawer"
app:menu="@menu/item_drawer">
<include layout="@layout/header_drawer"/>
</android.support.design.widget.NavigationView>

I couldn't get Lornes answer to work, but I had some success by using a custom NavigationView. It's very hacky but achieves the desired effect.
The methods added to the custom NavigationView allow you to add a header on top of the NavigationView then size the menu so it fits beneath the header.
Comments for improvements are welcome
The overrided NavigationView
public class CustomNavigationView extends NavigationView {
public CustomNavigationView(Context context) {
super(context);
}
public CustomNavigationView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomNavigationView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
// Consumes touch in the NavigationView so it doesn't propagate to views below
public boolean onTouchEvent (MotionEvent me) {
return true;
}
// Inflates header as a child of NavigationView
public void createHeader(int res) {
LayoutInflater inflater = LayoutInflater.from(getContext());
View view = inflater.inflate(res, this, false);
// Consumes touch in the header so it doesn't propagate to menu items below
view.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event){
return true;
}
});
addView(view);
}
// Positions and sizes the menu view
public void sizeMenu(View view) {
// Height of header
int header_height = (int) getResources().getDimension(R.dimen.nav_header_height);
// Gets required display metrics
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
float screen_height = displayMetrics.heightPixels;
// Height of menu
int menu_height = (int) (screen_height - header_height);
// Layout params for menu
LayoutParams params = new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.BOTTOM;
params.height = menu_height;
view.setLayoutParams(params);
}
}
And this in the onCreate of main activity
// Inflates the nav header
CustomNavigationView navigationView = (CustomNavigationView) findViewById(R.id.your_nav_view);
navigationView.createHeader(R.layout.your_nav_header);
// sizes nav drawer menu so it appears under header
ViewGroup parent = (ViewGroup) navigationView;
View view = parent.getChildAt(0);
navigationView.sizeMenu(view);

I also faced thhis problem and resolved it . here is the solution
1) Create default navigation drawer in your project
2) remove header tag from NavigationView in activity_main.xml and add header inside NavigationView
<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_main" >>>>>> X
app:menu="@menu/activity_main_drawer" >
<include
layout="@layout/nav_header_main"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.NavigationView>
3) add required blank items in top of menu->activity_main_drawer.xml (depand on your header height

I solved this problem by doing
<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/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
//where your main content goes.
<include
layout="@layout/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<include
layout="@layout/nav_drawer_layout"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true" />
Inside drawer layout, included add this layout,
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/nav_drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
//your header layout.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/nav_header_height"
android:gravity="bottom"
android:orientation="vertical">
<include layout="@layout/layout_drawer_header"></include>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/drawerRecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:layout_weight="1"
android:background="#ffffff" />
//your footer layout
<include layout="@layout/nav_footer_item" />
Then just populate the recyclerview.

change it to below code (include header inside)
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="@menu/drawer" />
<include layout="@layout/header"/>
</android.support.v4.widget.DrawerLayout>
work like charm happy coding :)
