       </LinearLayout>
         </LinearLayout>
          </LinearLayout>

you can insert a

<View android:layout_height="0dp" android:layout_width="0dp" android:layout_weight="1"/>

right before your buttons.

Or use a relative layout with alignParentBottom="true"

You need a RelativeLayout instead of a LinearLayout as parent; then simply drag the buttons in the layout-GUI to the bottom and they should stick there. When i am at home i am able to post "real" example code.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout …>
<!-- your posted code -->

Dragging the button's layout parent to the bottom will produce:

alignParentBottom="true"
