关于Etar日历库仅使用Day View模式及精简相关类的技术咨询

Hey there! Great choice picking Etar—it's a solid, well-structured calendar library. If you only need the Day View and want to slim down the codebase by removing unused classes, here's a step-by-step approach I've used before:

First, locate the main classes that power the Day View. In Etar's codebase, these are typically:

• DayFragment.java (or DayFragment.kt if you're using the Kotlin variant)
• DayView.java/DayView.kt (the actual view rendering component)
• DayAdapter.java/DayAdapter.kt (handles event items in the day view)
• DayController.java/DayController.kt (manages logic like event loading, interactions)

Also, keep an eye on any utility classes directly used by these—things like EventUtils.java that handle event formatting specifically for day view, or TimeUtils.java for time-related calculations needed here.

Next, you need to figure out which other classes these core Day View components depend on. Use your IDE's "Find Usages" feature (Ctrl/Cmd + F7 in IntelliJ/Android Studio) to:

• Check each core Day View class for imports and method calls to other library classes
• Mark any class that's only referenced by Day View components as safe to keep (for now)
• Flag classes that are used by multiple views (like Month/Week View) – you'll need to either refactor those to keep only the parts used by Day View, or if they're too intertwined, consider keeping a trimmed-down version.

Now start cleaning out the parts you don't need:

• Delete entire fragments/activities related to Month View, Week View, Agenda View (e.g., MonthFragment.java, WeekActivity.java)
• Remove adapters, controllers, and views tied to those unused views
• Get rid of any resource files (layouts, drawables, strings) that are only used by the deleted components. Use your IDE's "Unused Resources" inspection to make this easier.
• If there's a core CalendarProvider or EventLoader class, trim it to only fetch data needed for Day View (e.g., events for a single day instead of a month).

After deleting files, you'll likely run into compilation errors. Fix these by:

• Removing imports for deleted classes in remaining files
• Refactoring any shared utility classes to remove code that's only used by unused views
• If you kept a shared class, make sure it only exposes methods needed by Day View. For example, if EventUtils had a method to format month view event titles, delete that method.

Finally, test the Day View extensively to ensure all functionality works:

• Verify event loading, creation, editing, and deletion
• Check scrolling, time slot interactions, and event click behavior
• Test edge cases like multiple events in the same time slot, all-day events, and empty days

A quick pro tip: If you're using version control (like Git), make a branch before starting this cleanup. That way you can easily revert if you accidentally delete something critical!
