Java swing日历控件，界面精美，使用方便，能用于个人作品首先，声明一点，这个控件是我从一套据说价值九百多美元的swing类包中提取出来，并加以修改的，所以：
一，你不能把该控件用于任何商业产品中。

二，该控件没有源代码。

（DatePicker.java除外，这个是我加进去的）
三，该控件可以用于你的个人作品中。

截图如下：
使用之前请把datepicker.jar导入classpath中
使用方法如下：
DatePicker datepick = new DatePicker();
或者
datepick = new DatePicker(date,DefaultFormat,font,dimension);//自定义参数值
//各参数含义如下
//参数1 设置该控件的初始值（可选）
//参数2 设置日期的格式（可选）
//参数3 设置该控件的字体（可选）
//参数3 设置该控件的大小（可选）
//该控件继承自JComponent ，它继承了Jcomponent的属性
datepick.setTimePanleVisible(true);//设置时钟面板可见
atepick.setHightlightdays(hilightDays, Color.red);//设置一个月份中需要高亮显示的日子
datepick.setDisableddays(disabledDays);//设置一个月份中不需要的日子，呈灰色显示。

calendarview 用法CalendarView 是一个展示日历的控件，可以通过在布局文件中使用<CalendarView>标签来添加。

同时还可以通过代码来动态设置属性和监听事件。

以下是一些常用方法和属性的使用方法：1. 设置选中日期的最小值和最大值：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setMinDate(minDate.getTime()); // 设置最小日期calendarView.setMaxDate(maxDate.getTime()); // 设置最大日期```2. 监听日期选中事件：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {@Overridepublic void onSelectedDayChange(@NonNull CalendarView view, int year, int month, int dayOfMonth) {// 处理选中日期的逻辑}});```3. 设置是否显示周数：```javaCalendarView calendarView = findViewById(R.id.calendarView); calendarView.setShowWeekNumber(true); // 显示周数calendarView.setShowWeekNumber(false); // 不显示周数```4. 设置选中日期的背景色：```javaCalendarView calendarView = findViewById(R.id.calendarView);// 自定义选中日期的背景calendarView.setDateTextAppearance(R.style.SelectedDateStyle);// 或者使用系统默认的选中背景calendarView.setDateTextAppearance(android.R.style.TextAppear ance_DeviceDefault_Widget_DatePicker_Day_Selected);```5. 获取当前选中的日期：```javaCalendarView calendarView = findViewById(R.id.calendarView); long selectedDate = calendarView.getDate(); // 获取当前选中的日期，单位为毫秒```这些只是 CalendarView 的一些常用方法和属性，还有其他一些属性和方法可以根据需要进行查阅和使用。
