Pros of Etar-Calendar

• More modern and visually appealing user interface
• Better support for recurring events and complex calendars
• Integration with external calendars like Google Calendar

Cons of Etar-Calendar

• Less frequent updates and maintenance compared to Simple-Calendar
• Fewer customization options for colors and themes
• Slightly more complex to set up and configure

Code Comparison

Etar-Calendar (Event creation):

public void createEvent(String title, long startTime, long endTime) {
    ContentValues values = new ContentValues();
    values.put(CalendarContract.Events.TITLE, title);
    values.put(CalendarContract.Events.DTSTART, startTime);
    values.put(CalendarContract.Events.DTEND, endTime);
    // ... additional event properties
}

Simple-Calendar (Event creation):

fun insertEvent(event: Event) {
    val values = ContentValues().apply {
        put(Events.TITLE, event.title)
        put(Events.DESCRIPTION, event.description)
        put(Events.START_DATE, event.startTS)
        put(Events.END_DATE, event.endTS)
        // ... additional event properties
    }
}

Both projects use similar approaches for event creation, with Etar-Calendar using Java and Simple-Calendar using Kotlin. The main differences lie in the specific fields and data structures used, reflecting their individual design choices and feature sets.

Pros of react-native-calendars

• Cross-platform compatibility for iOS and Android
• Rich set of customizable components and themes
• Active development with frequent updates and community support

Cons of react-native-calendars

• Steeper learning curve for developers new to React Native
• Larger bundle size due to React Native dependencies
• Limited native calendar integration compared to Simple-Calendar

Code Comparison

Simple-Calendar (Kotlin):

override fun getEventTypes(callback: (List<EventType>) -> Unit) {
    ensureBackgroundThread {
        callback(eventTypesDB.getEventTypes())
    }
}

react-native-calendars (JavaScript):

const Calendar = () => (
  <CalendarList
    onDayPress={(day) => console.log('selected day', day)}
    markedDates={{
      '2023-05-16': {selected: true, marked: true, selectedColor: 'blue'}
    }}
  />
);

Simple-Calendar focuses on native Android development with Kotlin, providing deep integration with device calendars. react-native-calendars offers a more flexible, cross-platform solution with extensive customization options, but may require more setup and configuration for native calendar integration.

Pros of Calendar

• More customizable and flexible UI components
• Better support for complex calendar layouts and views
• Extensive documentation and sample code for implementation

Cons of Calendar

• Steeper learning curve for beginners
• Limited built-in functionality compared to Simple-Calendar
• Requires more code to implement basic calendar features

Code Comparison

Simple-Calendar (XML layout):

<com.simplemobiletools.commons.views.MyTextView
    android:id="@+id/month_view_holder"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Calendar (Kotlin implementation):

val calendarView = CalendarView(this)
calendarView.dayBinder = object : DayBinder<DayViewContainer> {
    override fun create(view: View) = DayViewContainer(view)
    override fun bind(container: DayViewContainer, day: CalendarDay) {
        container.textView.text = day.date.dayOfMonth.toString()
    }
}

Simple-Calendar provides a more straightforward implementation with pre-built views, while Calendar offers greater flexibility but requires more custom code. Simple-Calendar is better suited for quick, out-of-the-box solutions, whereas Calendar excels in scenarios requiring highly customized calendar interfaces.

Pros of Material-CalendarView

• More focused on providing a customizable calendar view component
• Offers a wider range of customization options for appearance and behavior
• Better suited for integration into existing Android applications

Cons of Material-CalendarView

• Less feature-rich as a standalone calendar application
• Requires more development effort to create a full-fledged calendar app
• May have a steeper learning curve for beginners

Code Comparison

Simple-Calendar (Kotlin):

override fun onCreateOptionsMenu(menu: Menu): Boolean {
    menuInflater.inflate(R.menu.menu_main, menu)
    return true
}

Material-CalendarView (Java):

@Override
public void onDateSelected(@NonNull MaterialCalendarView widget, @NonNull CalendarDay date, boolean selected) {
    // Handle date selection
}

The code snippets show different aspects of the projects. Simple-Calendar focuses on creating a full application with menus and UI elements, while Material-CalendarView provides callbacks for calendar-specific actions like date selection.

Both projects offer valuable solutions for different use cases. Simple-Calendar is better suited for users looking for a complete calendar application, while Material-CalendarView is ideal for developers who need a customizable calendar component for their Android apps.

Pros of Android-Week-View

• Specialized for week view calendar display, offering a more focused and optimized solution
• Highly customizable appearance and behavior through various attributes and methods
• Supports both vertical and horizontal scrolling for easy navigation

Cons of Android-Week-View

• Limited to week view functionality, lacking other calendar views like month or year
• Less comprehensive feature set compared to Simple-Calendar (e.g., no event management)
• May require more setup and configuration for basic usage

Code Comparison

Simple-Calendar (event creation):

val event = Event(id, title, startTS, endTS, description, reminder1Minutes,
    reminder2Minutes, reminder3Minutes, importId, flags, repeatInterval,
    repeatRule, repeatLimit, attendees, color)
eventsHelper.insertEvent(event)

Android-Week-View (event creation):

WeekViewEvent event = new WeekViewEvent(1, "Event", startTime, endTime);
event.setColor(getResources().getColor(R.color.event_color_01));
mWeekView.addEvent(event);

Both repositories offer calendar functionality for Android, but with different focuses. Simple-Calendar provides a full-featured calendar application with various views and event management capabilities. Android-Week-View, on the other hand, specializes in providing a customizable week view component for developers to integrate into their applications. The choice between the two depends on the specific requirements of the project and the level of customization needed.
