{ 
    "error": false, 
    "users": [ 
    {

    }, 
    { 
     "id": 3, 
     "username": "test2",

    ] 
} 

, und ich will es ändern Shamsi, was wie dieses 1395- aussehen sollte 11-26 13:42:26 Gibt es irgendeine Klasse, es zu tun?

Answer 1

Verwenden Joda Time

Als solche:

 Chronology iso = ISOChronology.getInstanceUTC(); 
     Chronology hijri = IslamicChronology.getInstanceUTC(); 

     LocalDate todayIso = new LocalDate(2013, 3, 31, iso); 
     LocalDate todayHijri = new LocalDate(todayIso.toDateTimeAtStartOfDay(), 
              hijri); 
     System.out.println(todayHijri); // 1434-05-19 

Um das Jahr, Monat und Tag zu erhalten aus der Zeichenfolge die folgende verwenden:

String startDateString = "2017-02-14 00:13:25"; 
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
Date date = df.parse(startDateString); 
Calendar calendar = new GregorianCalendar(); 
calendar.setTime(date); 

int year = calendar.get(Calendar.YEAR); 
//Add one to month {0 - 11} 
int month = calendar.get(Calendar.MONTH) + 1; 
int day = calendar.get(Calendar.DAY_OF_MONTH);

Sie können diese Klasse hinzufügen in Ihrem Projekt, source

import java.text.SimpleDateFormat; 
import java.util.Date; 

public class PersianDate { 
    public String todayShamsi() 
    { 
     SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd"); 
     String curentDateandTime = sdf.format(new Date()); 
     String year = curentDateandTime.substring(0, 4); 
     String month = curentDateandTime.substring(4, 6); 
     String day = curentDateandTime.substring(6, 8); 
     int Y = Integer.valueOf(year); 
     int M = Integer.valueOf(month); 
     int D = Integer.valueOf(day); 
     return Shamsi(Y, M, D); 
    } 
    public static String Shamsi(int Y, int M, int D) 
    { 
     if (Y == 0)
