AppBarLayout - Layout sometimes invisible once it enters view (even if it's not entered)

Question

I have a problem where sometimes the AppBarLayout will not show its full content all the time when you play around with it:

Answer 1

This is a solution extending the one provided above: Use this instead of the one provided, which will blend the appbarlayout and the subtle shadow elevation below it.

<View
    android:id="@+id/appbar_bottom"
    android:layout_width="match_parent"
    android:layout_height=".3dp"
    android:background="#606060"
    android:visibility="visible"/>

and the resultant layout:

<android.support.design.widget.AppBarLayout
        android:orientation="vertical"
        android:layout_height="148.3dp"
        android:layout_width="match_parent">

    <android.support.design.widget.TabLayout
            app:layout_scrollFlags="scroll|enterAlways"
            android:layout_height="48dp"
            android:background="@color/primarycolor"
            .../>

    <RelativeLayout
            app:layout_scrollFlags="scroll|enterAlways"
            android:background="@color/white"
            android:layout_height="100dp"
            ...>
    </RelativeLayout>

    <View
        android:id="@+id/appbar_bottom"
        android:layout_width="match_parent"
        android:layout_height=".3dp"
        android:background="#606060"
        android:visibility="visible"/>
</android.support.design.widget.AppBarLayout>
