You can place them in a LinearLayout and then set the width to "fill_parent" and the layout_weight to "1". Like this:

<LinearLayout android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:orientation="horizontal"
              android:layout_below="@id/text1">
    <Button android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:id="@+id/deleteButton_dialog"
            android:text="Delete" />
    <Button android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:id="@+id/cancelButton_dialog"
            android:text="Cancel"/>
</LinearLayout>
