Я получаю следующую ошибку в своем фрагменте:
java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to androidx.constraintlayout.widget.ConstraintLayout$LayoutParams
Я использую Скелет, чтобы скрыть данные, когда они еще не загружены, и я замечаю, что если я не использую этот Скелет макет, ошибка не появляется. Я не понимаю почему, потому что я использую макет Skeleton и в других фрагментах и не доставляет мне никаких проблем.
Это фрагмент кода:
