Bottom Legacy bar not appearing below ListView

Hi,

I want to add both top & bottom Legacy Bar in between ListView, but bottom Legacy bar not appearing below ListView. If i used same code in another activity not having ListView means, it working. Below is my code

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ab="http://schemas.android.com/apk/res/Xamarin.Android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
   <legacybar.library.bar.LegacyBar
     android:id="@+id/actionbar"
     style="@style/actionbar" />

   <ListView
        android:id="@+id/notesList"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />
   <legacybar.library.bar.LegacyBar
        android:id="@+id/bottomActionbar"
        style="@style/actionbar"
        ab:separator="@color/bottomactionbar_separator"
        ab:background="@drawable/bottomactionbar_background"
        ab:background_item="@drawable/bottomactionbar_btn" />

</LinearLayout>
