AppBarLayout Toolbar TabLayout ViewPager DrawerLayout

Question

I want to use a DrawerLayout in combination with a ViewPager which is connected to a TabLayout. On top I want the Toolbar.

This code brings the best results however, when the drawer is open it hides the toolbar.

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


<android.support.v4.widget.DrawerLayout
    android:id="@+id/my_drawer_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.support.v7.widget.Toolbar
            android:id="@+id/my_awesome_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:minHeight="?attr/actionBarSize" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="0dp"

            android:paddingTop="0dp"
            app:tabGravity="fill"


            app:tabMode="scrollable" />

        <com.sourcecastle.commons.controls.CustomViewPager
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />


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

    <LinearLayout
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="?attr/theme_background_color"
        android:choiceMode="singleChoice"

        android:orientation="vertical">


        <TextView
            android:id="@+id/tvTime"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:gravity="center"
            android:text="00:00:00"
            android:textAppearance="?android:attr/textAppearanceLarge" />


        <TextView
            android:id="@+id/tvDistance"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"

            android:text="123km"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:visibility="gone" />

        <LinearLayout
            android:id="@+id/llMap"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:orientation="vertical">

            <fragment
                android:id="@+id/speedFragment"
                class="com.sourcecastle.logbook.fragments.SpeedFragment"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                android:layout_weight=".60" />

            <fragment
                android:id="@+id/mMap"
                class="com.google.android.gms.maps.SupportMapFragment"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight=".40" />
        </LinearLayout>

        <TextView
            android:id="@+id/tvEnlarge"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"

            android:gravity="center"
            android:text="@string/enlarge"
            android:textAppearance="?android:attr/textAppearanceLarge" />

    </LinearLayout>

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

I already tried almost all combinations and read a lot of posts. Also the simmilar question here: Android CoordinatorLayout + TabLayout + ViewPager Toolbar not hidding on scroll

When I bring out the AppBarLayout and leave the ViewPager in the DrawerLayout the ViewPager is unter the TabLayout and Toolbar.

To this Linear Layout give top margin of the height of your toolbar

<LinearLayout
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="?attr/theme_background_color"
    android:choiceMode="singleChoice"
    android:layout_marginTop="?attr/actionBarSize"
    android:orientation="vertical">
