System.err При использовании конструктора библиотеки Kotlin в проекте Java ⇐ Android

[Anonymous]

Я включил библиотеку Kotlin (https://github.com/ognev-zair/kotlin-agendacalendarview) в свой проект Java. Используя рекомендацию из других сообщений, я могу получить проект, чтобы скомпилировать, и это половина работает. Используя информацию в файле readme на GitHub, я преобразовал ее в Java и создал следующие классы: < /p>
mainActivity < /p>
public class AgendaActivity2 extends AppCompatActivity implements CalendarController {

private AgendaCalendarView agendaCalendarView;
private CalendarContentManager contentManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_agenda2);

agendaCalendarView = findViewById(R.id.agenda_calendar_view_2);

agendaCalendarView.getAgendaView().getAgendaListView().setSaveEnabled(false);

// Setup date range
Calendar minDate = Calendar.getInstance();
Calendar maxDate = Calendar.getInstance();
minDate.add(Calendar.MONTH, -10);
minDate.add(Calendar.YEAR, -1);
minDate.set(Calendar.DAY_OF_MONTH, 1);
maxDate.add(Calendar.YEAR, 1);

// Create your event adapter (implemented below)
EventAgendaAdapter adapter = new EventAgendaAdapter(this);

// Initialize the calendar content manager
contentManager = new CalendarContentManager(
this,
agendaCalendarView,
adapter
);
contentManager.setLocale(Locale.getDefault());
contentManager.setDateRange(minDate, maxDate);

List events = new ArrayList();
Calendar eventStart = Calendar.getInstance();
Calendar eventEnd = Calendar.getInstance();
eventEnd.add(Calendar.HOUR, 2);

events.add(new MyCalendarEvent(
eventStart,
eventEnd,
new DayItem(eventStart.getTime(), eventStart.getFirstDayOfWeek(),false,"March"),
new Event("Meeting", "Project discussion")
));

eventStart.add(Calendar.DAY_OF_MONTH,2);
eventEnd.add(Calendar.DAY_OF_MONTH,2);

events.add(new MyCalendarEvent(
eventStart,
eventEnd,
new DayItem(eventStart.getTime(), eventStart.getFirstDayOfWeek(),false,"March"),
new Event("Meeting", "Project discussion")
));

contentManager.loadItemsFromStart(events);
}

// CalendarController interface methods:

@Override
public int getEmptyEventLayout() {
// Return your layout resource for an "empty event"
return R.layout.empty_event_item;
}

@Override
public int getEventLayout() {
// Return your layout resource for an event item
return R.layout.event_item;
}

@Override
public void onDaySelected(IDayItem dayItem) {
// Handle a day being selected
Toast.makeText(this, "Day selected: " + dayItem.getDate(), Toast.LENGTH_SHORT).show();
}

@Override
public void onScrollToDate(Calendar calendar) {
// Optionally, handle scroll events (e.g., update toolbar title)
}
}
< /code>
eventagendaadapter < /p>
public class EventAgendaAdapter extends DefaultEventAdapter {
private final SimpleDateFormat headerFormat;

public EventAgendaAdapter(Context context) {
headerFormat = new SimpleDateFormat(
"ddd MM yyyy",
Locale.ENGLISH
);
}

@Override
public int getEventLayout(boolean hasEvent) {
return hasEvent ? R.layout.event_item : R.layout.empty_event_item;
}

@Override
public int getHeaderLayout() {
return R.layout.view_agenda_header;
}

@Override
public void getEventItemView(@NonNull View view,
@NonNull CalendarEvent event,
int position) {
TextView title = view.findViewById(R.id.event_title);
TextView desc = view.findViewById(R.id.event_time);

if (event.getEvent() instanceof Event) {
Event javaEvent = (Event) event.getEvent();
title.setText(javaEvent.getName());
desc.setText(javaEvent.getDescription());
}
}

@Override
public void getHeaderItemView(@NonNull View view, @NonNull Calendar day) {
TextView header = view.findViewById(R.id.view_agenda_day_of_month);
header.setText(headerFormat.format(day.getTime()));
}
}

mycalendarevent < /p>
public class MyCalendarEvent extends BaseCalendarEvent {

private Calendar startTime = Calendar.getInstance();

public MyCalendarEvent(){}

public MyCalendarEvent(Calendar start, Calendar end,
IDayItem dayItem, Event event) {

this.dayReference = dayItem;
this.event = event;
}

@NotNull
@Override

@NotNull
@Override
public Calendar getEndTime() { return endTime; }

@Nullable
@Override
public Object getEvent() { return event; }

@Override @NotNull
public MyCalendarEvent copy() {
return new MyCalendarEvent(
(Calendar) startTime.clone(),
(Calendar) endTime.clone(),
dayReference,
(Event) event
);
}

@Override
public boolean hasEvent() {
return event != null;
}
}
< /code>
событие < /p>
public class Event {
private long id;
private String name;
private String description;

public Event(String name, String description) {
this.name = name;
this.description = description;
}

// Getters and setters
public String getName() { return name; }
public String getDescription() { return description; }
}
< /code>
Я получаю систему.constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {}
< /code>
constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {

val inflater = context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
inflater.inflate(R.layout.view_agenda, this, true)

(findViewById(R.id.refresh_layout) as SwipeRefreshLayout).isEnabled = false
}
< /code>
constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {

...

val inflater = context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
inflater.inflate(R.layout.view_agendacalendar, this, true)
}
< /code>
Following your advice in the comment, I searched the logcat in more detail and found more information:
