Estou tentando adicionar outra barra de ação ou menu à parte inferior do layout da minha atividade e manter a barra de ação superior.

Algo assim :

Aqui está o meu layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.yasser.version6.PublierActivity">


<include
    android:id="@+id/toolbar"
    layout="@layout/toolbar" />



<RelativeLayout
     android:layout_width="fill_parent"
     android:layout_height="match_parent"
     >


    <LinearLayout
        android:layout_width="fill_parent"
        android:id="@+id/user"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="1">


        <ImageView
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_gravity="center"
            android:layout_margin="4dp"
            android:id="@+id/profil_image"
            android:layout_alignParentTop="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_marginRight="218dp"
            android:layout_marginEnd="218dp" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textMultiLine|textCapSentences"
            android:ems="10"
            android:background="#00000000"
            android:layout_margin="4dp"
            android:hint="Écriver quelque chose..."
            android:id="@+id/publication_text"
            android:maxLength="150"
            android:textSize="15dp"
            android:maxLines="3"
            android:layout_alignParentTop="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true">
            <requestFocus />
        </EditText>


    </LinearLayout>




    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="@dimen/image_size"
        android:id="@+id/publication_image"
        android:layout_weight="1"
        android:padding="0dp"
        android:background="@drawable/default_image"
        android:layout_marginTop="5dp"
        android:scaleType="fitXY"
        android:layout_below="@+id/user" />

</RelativeLayout>

Tentei adicionar um RelativeLayout personalizado que parece quase uma barra de ação, mas a barra de ferramentas sobe e atrapalha tudo.
