This LinearLayout probably isn't necessary if the layout_height for the button
is "wrap_content"

Yes, that works.

+        <Button
+            android:id="@+id/clear_button"
+            style="?android:attr/buttonBarButtonStyle"
+            android:layout_width="match_parent"
+            android:layout_height="match_parent"
+            android:focusable="true"
+            android:text="@string/clear_data_delete" />
+    </LinearLayout>

+</LinearLayout>
