推荐答案

你可以使用 JodaTime 库，以获得有效的结果。

You can use JodaTime library for efficient results.

String dateStr = "04/05/2010"; SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yyyy"); Date dateObj = null; try { dateObj = curFormater.parse(dateStr); } catch (ParseException e) { e.printStackTrace(); } Period age = calcDiff(dateObj,new Date()); Toast.makeText(this, PeriodFormat.wordBased().print(age),Toast.LENGTH_SHORT).show();

并使用此方法获取差异

private Period calcDiff(Date startDate,Date endDate) { DateTime START_DT = (startDate==null)?null:new DateTime(startDate); DateTime END_DT = (endDate==null)?null:new DateTime(endDate); Period period = new Period(START_DT, END_DT); return period; }

或根据您的要求，您可以更改 PeriodFormat 像这样

or as per your requirement you can change PeriodFormat like this

PeriodFormatter mPeriodFormat; mPeriodFormat = new PeriodFormatterBuilder().appendYears().appendSuffix(" year(s) ").appendMonths().appendSuffix(" month(s) ").appendDays().appendSuffix(" day(s) ").printZeroNever().toFormatter(); Toast.makeText(this,mPeriodFormat.print(age),Toast.LENGTH_SHORT).show();
