CalendarView, optimized for seasons
Add the library into your project using Gradle. Put it in (normally, it should be) app/build.gradle:
implementation 'com.acaziasoft.highlightedcalendarview:highlightedcalendarview:1.0.1'
Use in the XML layout file like so:
<com.acaziasoft.highlightedcalendarview.CalendarView
app:dateFormat="MMMM yyyy"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Where app:dateFormat is SimpleDateFormat compatible.
