This is my xml.

Answer 1

Maybe it's an old answer but there are 2 simple solutions:

1. Toolbar with layout_marginBottom

If you need to have a transparent (or semi transparent) TabLayout then you can do something like this:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        app:titleEnabled="false">

        <YourMagicViewWithBackgroundImageTextAndOtherStuff
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="48dp"
            android:background="@color/semiTransparentHeaderBg"
            app:layout_collapseMode="pin" />

        <android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="48dp"
            android:layout_gravity="bottom"
            android:background="@color/semiTransparentHeaderBg" />

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

2. TabLayout outside CollapsingToolbarLayout

If you don't need to have a transparent TabLayout then just put them outside CollapsingToolbarLayout as kris larson or winter suggests. AppBarLayout extend from LinearLayout so everything should works flawlessly.

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        app:titleEnabled="false">

        <YourMagicViewWithBackgroundImageTextAndOtherStuff
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/semiTransparentHeaderBg"
            app:layout_collapseMode="pin" />

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

    <android.support.design.widget.TabLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

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

In your CollapsingToolbarLayout each ImageView,TextView set

android:layout_below="@+id/yourid "

set each widget one by one below of other widget based on your designview order.
