Answer 1

You can do something like this inside a relative layout

<LinearLayout android:id="@+id/footer" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:orientation="horizontal"
    android:layout_alignParentBottom="true" style="@android:style/ButtonBar">

    <Button android:id="@+id/saveButton" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_weight="1"
        android:text="@string/menu_done" />

    <Button android:id="@+id/cancelButton" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_weight="1"
        android:text="@string/menu_cancel" />
</LinearLayout>

Answer 2

You can use a FrameLayout to put something in the bottom by:

android:layout_gravity="bottom|center"

For example:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    >
    <ListView
        android:id="@+id/list1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        />
    <Button
        android:id="@+id/btn_"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center"
        android:text="OK"
        />

</FrameLayout>
