Нет такой ошибки поля в android проекте с использованием kotlin

Question

Я получаю Ошибка выполнения NoSuchField в моем приложении android с использованием Kotlin, в то время как поле существует, я попытался переименовать, как указано здесь Нет stati c Поле list_container типа I в классе Landroid / support / v7 / preference / R $ id пока нет решения

Это мой класс MainActivityWarrant

Answer 1

Я полагаю, что ваша проблема в том, что ни в одном из ваших xml нет элемента, который имеет идентификатор "frag_contain". Не могли бы вы проверить, совпадает ли ваш идентификатор с тем элементом, который вы ищете? Должно выглядеть примерно так:

<android.widget.FrameLayout
        android:id="@+id/fragment_contain"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
