CalendarView
CalendarView is a high-performance Android UI component designed for displaying dates and navigating chronological views. It functions as a canvas-based widget that utilizes direct drawing instead of standard list views to minimize memory usage and ensure fast rendering of complex date interfaces.
The component provides a programmable interface for switching between month, week, year, and lunar views. It differentiates itself through a pluggable customization system that allows developers to override the drawing logic for dates, text, event markers, and selection layouts.
The library supports multiple date selection modes, including single, multiple, and range-based picking, with the ability to restrict specific dates from being selectable. It includes integration for nested scrolling containers and tools for configuring structural parameters such as the starting day of the week.
