В настоящее время я создаю пользовательский диалог для отображения часов с 00:00 до 23:59, я использую kotlin в качестве языка разработки. Моя проблема в том, что когда я открываю диалоговое окно, экран гаснет и ничего не отображается, я думаю, что я сделал все правильные шаги. Ошибки не отображаются, но перед тем, как я поместил '?' в recyclerViewCalendar? [Calendar Dialog Class], он выдал мне нулевую ошибку в переменной. Это мой код
Класс диалога календаря
class CalendarDialog : DialogFragment() {
/**
* Define variables
*/
private val mDaysList : MutableList<Days> = ArrayList()
private val dayMonthYear = "2018-06-14" //TODO fetch the date of today
/**
* Initialize the adapter
*/
private val adapter = CalendarAdapter(mDaysList)
/**
* Initialize the layout manager
*/
private fun getLinearLayoutManager(): LinearLayoutManager {
return LinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false)
}
private fun initView() {
setDataListItems()
recyclerViewCalendar?.adapter = adapter
recyclerViewCalendar?.layoutManager = getLinearLayoutManager()
recyclerViewCalendar?.setHasFixedSize(true)
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
val rootView = inflater.inflate(R.layout.calendar_dialog, container)
initView()
return rootView
}
/**
* TODO dependendo do horário da clinica bloqueio e desbloqueio horários
*/
private fun setDataListItems() {
mDaysList.add(Days("06:00", dayMonthYear))
mDaysList.add(Days("06:30", dayMonthYear))
mDaysList.add(Days("07:00", dayMonthYear))
