Android java.lang.ClassCastException: android.widget.LinearLayout $ LayoutParams нельзя отбрасывать в android.widget.AbsListView $ LayoutParams

Question

Я получаю эту ошибку при запуске моего приложения на более старом телефоне Android (Android 4.4.2). Код работает на новом телефоне (Android 5.0) и не выдает ошибку. Это полная ошибка.
