日期选择器代码与所有地方相同
我的约会格式:
1990/06/07(获取此格式)
我需要计算年龄,即当前日期 - DOB 2016-1990 = 26
代码:
public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar calendar = Calendar.getInstance();
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
int a = yy - calendar.get(Calendar.YEAR);
Log.e("999999", String.valueOf(a));
return new DatePickerDialog(getActivity(), this, yy, mm, dd);
}

您可以使用JodaTime库来获得有效的结果。
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();
并使用此方法获得差异
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,您可以像这样更改PeriodFormat
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();
