Pros of material-calendarview

• More modern Material Design aesthetic
• Supports custom decorators for date cells
• Offers more customization options for appearance

Cons of material-calendarview

• Larger library size
• May require more setup for basic functionality
• Less established/mature compared to android-times-square

Code Comparison

material-calendarview:

MaterialCalendarView calendarView = findViewById(R.id.calendarView);
calendarView.setSelectionMode(MaterialCalendarView.SELECTION_MODE_MULTIPLE);
calendarView.addDecorator(new EventDecorator(Color.RED, dates));

android-times-square:

CalendarPickerView calendar = findViewById(R.id.calendar_view);
calendar.init(startDate, endDate)
    .inMode(CalendarPickerView.SelectionMode.MULTIPLE);

material-calendarview offers more built-in customization options, while android-times-square provides a simpler API for basic functionality. The former allows for easy decoration of specific dates, while the latter focuses on a straightforward date selection process.

Both libraries serve the purpose of providing a calendar view for Android applications, but material-calendarview leans more towards modern design principles and extensive customization. android-times-square, developed by Square, is known for its reliability and simplicity, making it a solid choice for projects that don't require advanced styling options.

Pros of Calendar

• More flexible and customizable, allowing for a wider range of calendar styles and layouts
• Supports both vertical and horizontal scrolling
• Better performance for handling large date ranges

Cons of Calendar

• Steeper learning curve due to increased complexity and customization options
• Requires more setup code for basic implementations
• Less mature project with potentially fewer community resources

Code Comparison

Calendar:

val calendarView = CalendarView(context)
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()
    }
}

TimesSquare:

CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
Calendar nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 1);
calendar.init(new Date(), nextYear.getTime())
    .withSelectedDate(new Date());

The Calendar library offers more granular control over day rendering and binding, while TimesSquare provides a simpler setup for basic calendar functionality. Calendar's code is in Kotlin, which may be preferred by some developers, while TimesSquare uses Java.

Pros of Caldroid

• More customizable appearance with support for custom cell views and backgrounds
• Supports both date picker and date range selection modes
• Includes built-in swipe navigation between months

Cons of Caldroid

• Less actively maintained (last update in 2019)
• Fewer stars and contributors on GitHub
• May have compatibility issues with newer Android versions

Code Comparison

Caldroid:

CaldroidFragment caldroidFragment = new CaldroidFragment();
Bundle args = new Bundle();
Calendar cal = Calendar.getInstance();
args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
caldroidFragment.setArguments(args);

android-times-square:

Calendar nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 1);
CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
calendar.init(new Date(), nextYear.getTime())
    .withSelectedDate(new Date());

Both libraries offer easy-to-use calendar views for Android applications. Caldroid provides more customization options and flexibility in terms of appearance and selection modes. However, android-times-square is more actively maintained and likely to have better compatibility with recent Android versions. The code snippets show that both libraries have straightforward initialization processes, with Caldroid using a fragment-based approach and android-times-square using a view-based approach.

Pros of MaterialDateTimePicker

• Offers both date and time picker functionality
• Follows Material Design guidelines for a modern, sleek appearance
• Supports theming and customization options

Cons of MaterialDateTimePicker

• May have a steeper learning curve due to more complex implementation
• Potentially larger library size due to additional features

Code Comparison

MaterialDateTimePicker:

Calendar now = Calendar.getInstance();
DatePickerDialog dpd = DatePickerDialog.newInstance(
    this,
    now.get(Calendar.YEAR),
    now.get(Calendar.MONTH),
    now.get(Calendar.DAY_OF_MONTH)
);
dpd.show(getFragmentManager(), "Datepickerdialog");

android-times-square:

Calendar nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 1);
CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
calendar.init(new Date(), nextYear.getTime())
    .withSelectedDate(new Date());

MaterialDateTimePicker offers a more comprehensive date and time selection solution with a modern design, while android-times-square focuses on a simpler, calendar-based date selection. The code examples show that MaterialDateTimePicker uses a dialog-based approach, whereas android-times-square integrates directly into the layout. Choose based on your specific needs and design preferences.

Pros of Android-Week-View

• Offers a more comprehensive week view with customizable event display
• Supports horizontal scrolling for navigating between weeks
• Provides zoom functionality for adjusting the time scale

Cons of Android-Week-View

• More complex implementation due to additional features
• May have a steeper learning curve for developers
• Potentially higher resource consumption due to advanced functionality

Code Comparison

Android-Week-View:

WeekView weekView = findViewById(R.id.weekView);
weekView.setOnEventClickListener(this);
weekView.setMonthChangeListener(this);
weekView.setEventLongPressListener(this);

android-times-square:

CalendarPickerView calendar = findViewById(R.id.calendar_view);
Date today = new Date();
calendar.init(today, nextYear.getTime())
    .withSelectedDate(today);

Android-Week-View provides a more detailed week view with event handling capabilities, while android-times-square focuses on a simpler month-based calendar picker. The code snippets demonstrate the initialization process for each library, highlighting the different approaches to calendar functionality.

Pros of CompactCalendarView

• More customizable appearance with options for event indicators and day labels
• Supports horizontal scrolling for month navigation
• Smaller footprint and easier integration into existing layouts

Cons of CompactCalendarView

• Less comprehensive date range selection functionality
• Fewer built-in themes and styling options
• Limited support for custom date formats

Code Comparison

CompactCalendarView:

CompactCalendarView compactCalendarView = (CompactCalendarView) findViewById(R.id.compactcalendar_view);
compactCalendarView.setUseThreeLetterAbbreviation(true);
compactCalendarView.setFirstDayOfWeek(Calendar.MONDAY);
compactCalendarView.setIsRtl(false);
compactCalendarView.displayOtherMonthDays(false);

android-times-square:

CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
Date today = new Date();
calendar.init(today, nextYear.getTime())
    .inMode(CalendarPickerView.SelectionMode.SINGLE)
    .withSelectedDate(today);

Both libraries offer easy-to-use calendar views for Android applications. CompactCalendarView provides a more compact and customizable appearance, while android-times-square offers robust date range selection and built-in theming options. The choice between the two depends on specific project requirements and design preferences.
