I recommend to use XML.

Add this to your XML:

<Button
        android:layout_height="wrap_content"
        android:id="@+id/button"
        android:text="Button" 
        android:layout_width="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
