Date 对象. Date 对象用于处理日期与时间。. 创建 Date 对象： new Date () 以下四种方法同样可以创建 Date 对象：. var d = new Date (); var d = new Date (milliseconds); // 参数为毫秒 var d = new Date (dateString); var d = new Date (year, month, day, hours, minutes, seconds, milliseconds); milliseconds 参数是 Android provides controls for the user to pick a time or date as ready-to-use dialogs. These pickers provide controls for selecting each part of the time (hour, minute, AM/PM) or date (month, day, year). Note: For a better user experience, see the Material Design date picker and time picker documentation. Figure 1. First you should to get the first day from date from your input year and month 2017/February; Second you should to get the number of days of this month; Third you should to loop until the number to your days in your case from 1 to 28 and add a day to your date The year in a Date starts from 1900, while most of the date operations usually use Epoch time which starts from January 1st, 1970. Also, the day, month and year offset of a Date is counterintuitive. Days start at 0, while month begins from 1. To access any of them, we must use the Calendar class. If you don't want to deal with a 3rd party library, then get Date objects representing the two dates in question and call getTime() on both, subtract the latest from the earliest and you'll have the delta between the dates in milliseconds. The maths to convert that into years/months/days etc is trivial.* Something like: KVzjy.
