Fix bottom bar in CoordinatorLayout

Question

I have a CoordinatorLayout which contains AppBarLayout and a FrameLayout which contains fragments.

One of this fragment contains a TabLayout at Top, one List trough RecyclerView and at the Bottom one "homemade" toolbar.

The AppBarLayout is configured with app:layout_scrollFlags="scroll|enterAlways"

My problem is that both "toolbars" are hiding when scroll, the AppBarLayout and my "homemade" toolbar at the bottom. This is the current behaviour

I would like to fix the bottom "homemade" toolbar to keep visible but I can't achieve it.

This is the XML of the fragment Layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    <android.support.design.widget.TabLayout
        android:id="@+id/toolbarfilter"
        android:layout_width="match_parent"
        android:background="@color/azul_asde"
        app:tabMode="fixed"
        app:tabMaxWidth="0dp"
        android:elevation="4dp"

        android:visibility="visible"
        >
        <ImageView

            android:tint="@color/gris_desactivado" />
        <ImageView
            android:id="@+id/select"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/ic_bookmark_border_white_24dp"/>

        <ImageView
            android:id="@+id/send"
            android:layout_width="0dp"

            android:src="@drawable/ic_send_white_24dp"
            android:tint="@color/gris_desactivado" />

    </LinearLayout>

</LinearLayout>

Try this layout :
