Я создал 2 recyclerView внутри ConstraintLayout , который ограничен по горизонтали с chainStyle layout_constraintHorizontal_chainStyle="spread_inside", однако я хочу перевернуть их симметрично, используя ConstraintSet Очистить и Подключить . Когда я пытаюсь соединить виджеты с ConstraintSet CHAIN_SPREAD_INSIDE, появляется эта ошибка

java .lang.IllegalArgumentException: справа налево undefined в android .support .constraint.ConstraintSet.connect (ConstraintSet. java: 1260)

, вот рисунок, который более подробно объясняет эту проблему, спасибо за помощь. enter image description here
