XML : Toolbar overlaps status bar

I've got a problem with my status bar which gets overlapped by the toolbar.

I wanted to have the function that when the user scrolles the ListView down, the toolbar disappears behind the status bar so that only the tabs are visible, just like in the WhatsApp and YouTube apps.

To achieve this effect or to get this function I used this line:

  app:layout_scrollFlags="scroll|enterAlways"    

into my android.support.v7.widget.Toolbar, but know as I said before, the status bar gets overlapped by the toolbar.

  <?xml version="1.0" encoding="utf-8"?>  <android.support.design.widget.CoordinatorLayout      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/main_content"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:fitsSystemWindows="true"      tools:context=".MainActivity">        <android.support.design.widget.AppBarLayout          android:id="@+id/appbar"          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:paddingTop="@dimen/appbar_padding_top"          android:theme="@style/AppTheme.AppBarOverlay">            <android.support.v7.widget.Toolbar              android:id="@+id/toolbar"              android:layout_width="match_parent"              android:layout_height="?attr/actionBarSize"              app:layout_scrollFlags="scroll|enterAlways"              android:background="?attr/colorPrimary"              app:popupTheme="@style/AppTheme.PopupOverlay">            </android.support.v7.widget.Toolbar>            <android.support.design.widget.TabLayout              android:id="@+id/tabs"              android:layout_width="match_parent"              android:layout_height="wrap_content" />        </android.support.design.widget.AppBarLayout>        <android.support.v4.view.ViewPager          android:id="@+id/container"          android:layout_width="match_parent"          android:layout_height="match_parent"          app:layout_behavior="@string/appbar_scrolling_view_behavior" />      </android.support.design.widget.CoordinatorLayout>    

Thankful for any help!
