Navbar - won't go infront of the body when scrolling

Question

I am trying to get my navigation bar to appear on top of the body when scrolling. Currently it goes below as images shows.

I have a navdrawer also which has stopped working since introducing the scrollview... I feel as though this could be because when I click the 'hamburger' icon it is actually behind the scroll view so doesn't work but not sure... just want to get this bit done then I will find out if that the reason I guess. Thank you.

Layout xml for that page is also below.

What happens:

XML:

Go through this link on [how to use coordinatior layout](http://saulmm.github.io/mastering-coordinator) and [this](https://stackoverflow.com/questions/32523188/coordinatorlayout-appbarlayout-navigationdrawer) for using coordinatior layout with drawerlayout. — , Dec 22 '17 at 12:36
That seems like a lot of rework, considering all the pages I have, is there any simpler way or will I have to take that approach? — user3095083, Dec 22 '17 at 12:39
No, actually it isn't. You just have to use the second [link](https://stackoverflow.com/questions/32523188/coordinatorlayout-appbarlayout-navigationdrawer) for this issue. See the accepted answer. — , Dec 22 '17 at 12:40

activity_edit_appointment.xml contains a DrawerLayout as a parent view with sub-subsequent children as CoordniatorLayout and NavigationView 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"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">

<android.support.design.widget.CoordinatorLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/overview_coordinator_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">


        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimaryDark"
            app:layout_scrollFlags="enterAlways|scroll" />

    </android.support.design.widget.AppBarLayout>

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <include layout="@layout/your_contents" />

    </android.support.v4.widget.NestedScrollView>


</android.support.design.widget.CoordinatorLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/nvView"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@android:color/white"
    app:headerLayout="@layout/nav_header"
    app:menu="@menu/navigationdrawer_main" />
  </android.support.v4.widget.DrawerLayout>

your_contents.xml will contain views you want to display for current activity.

 <LinearLayout

                android:text="Save Notes" />

            <Button
                android:id="@+id/NSndEml"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="Send Email" />
        </LinearLayout>

    </LinearLayout>

you can place your navigation drawer inside these 2 xml files: nav_header.xml(will give you a header like gmail app) and navigationdrawer_main.xml(specify your drawer entries inside this menu file)

To give title to the toolbar, you can either do it programatically or just give android:label="Edit Appointment" to this activity's activity tag in AndroidManifest.xml.

sorry I think I am slowing getting there!! Now using code above though I am getting DrawerLayout must be measured with MeasureSpec.EXACTLY error I can see it is something to do with the height/width just can't find the issue... any chance you know exactly what is causing it? — user3095083, Dec 22 '17 at 13:53
