У меня есть TabHostAdapter, который содержит 3 фрагмента.Но второй фрагмент всегда вылетает, когда я использую андроид болотный телефон (или эмулятор).Я обнаружил, что сбой произошел из моего макета, но я не выяснил, почему .. Если я использую последний телефон с Android, проблем нет
Я получаю следующую ошибку:
java.lang.NullPointerException: попытка вызвать виртуальный метод int android.view.View.getVisibility () для нулевой ссылки на объект.
Вот моя функция:
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
// Inflate the layout for this fragment
return inflater!!.inflate(R.layout.fragment_second, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
//val activitySession : ActivitySession = arguments!!.getSerializable(Constants.ACTIVITY_SESSION) as ActivitySession
//val stats = activitySession.statistic
//showStats(stats)
//val laps = activitySession.laps
//showLaps(laps)
}
И мой макет:

РЕДАКТИРОВАТЬ 2:
Я обнаружил проблему, мне пришлось заменить все "«match_parent» атрибутом wrap_content для каждого компонента внутри моего TableLayout и TableRow.Итак, я думаю, что tableRow и TableLayout должны знать высоту / ширину компонента внутри них.(Это было сбой с версиями до Android Marshmallow)
