+         We need this padding to place @id/bottom_divider at the same position
+         regardless of @id/top_divider state.
+
+         Detail:
+         When ProgressBar is used in @id/top_divider, we have 7dip implicit
+         padding inside the ProgressBar object, while we don't have the
+         padding when View is used. As a result, all the objects below it
+         including @id/bottom_divider moves up/down in 7dip between those
+         two states. It is WAI for @id/content, but not for the others.
+
+         Note that we cannot let bottom dividers/buttons align with parent's
+         bottom edge using layout_alignParentBottom="true", since we'd like
+         to control bottom margin between @id/bottom_buttons and the edge
+         depending on software keyboard is shown/hidden.
+
+         We need to enclose @id/bottom_padding with @id/bottom_padding_layout
+         to let @id/bottom_divider use android:layout_below.
+         android:visibility="gone" really let the object go away,
+         causing @id/bottom_divider to lose the target for android:layout_below.
