        android:layout_gravity="bottom|center_horizontal">

Answer 1

What you need to do is to have this LinearLayout of yours put inside a RelativeLayout. The relative layout is preferably your root layout with fill_parent for height as it must reach the bottom.

then add this to your LinearLayout instead of the gravity:

android:layout_centerHorizontal="true" android:layout_alignParentBottom="true"

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
        <LinearLayout 
            android:layout_height="wrap_content" android:background="@color/black"
            android:id="@+id/ll_bookmarkslistad" android:layout_width="fill_parent"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
        >
            <!-- stuff inside layout -->
         </LinearLayout>
</RelativeLayout>

Try using a RelativeLayout with android:layout_alignParentBottom and android:layout_centerHorizontal
