Using windowTranslucentStatus with hidden Toolbar

Question

I'm trying to incorporate windowTranslucentStatus and AppBarLayout with Toolbar flagged with app:layout_scrollFlags="scroll|enterAlways"

Testing simultaneously on APIs 18, 19 and 22 (from the left).

Problem is on the highest API, where toolbar is partialy visible under the statusbar. I tried many many combinations of styles but this is the closest I got.

In styles I use:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:colorPrimary" tools:targetApi="lollipop">@color/primary</item>
    <item name="android:colorPrimaryDark" tools:targetApi="lollipop">@color/primary_dark</item>
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/primary</item>
    <item name="android:colorAccent" tools:targetApi="lollipop">@color/primary</item>
    <item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item>
    <item name="android:windowBackground">@color/background</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

Here is my layout xml:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    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:minHeight="?attr/actionBarSize"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

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

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/background"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />


<android.support.design.widget.FloatingActionButton
    android:id="@+id/add_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:backgroundTint="@color/green"
    app:layout_anchor="@id/recycler_view"
    app:layout_anchorGravity="bottom|right|end" />

I created sample app, which is available on github

Is there something missing in this puzzle?

Fixed it. It might not be the most beautiful solution, but it wokrs (tested on 19 and 22). I added a negative margin to the coordinator layout and a positive margin to the toolbar (25dp as this is the height of the status bar).

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/coordinator_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?attr/colorPrimary"
    android:fitsSystemWindows="true"
    android:layout_marginTop="-25dp">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        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:minHeight="?attr/actionBarSize"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            android:layout_marginTop="25dp"/>

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/background"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/add_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:backgroundTint="@color/green"
        app:layout_anchor="@id/recycler_view"
        app:layout_anchorGravity="bottom|right|end" />

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