come convertire i millisecondi in formato data in Android?

Question

Ho millisecondi. ho bisogno di essere convertiti in formato data di

esempio:

23/10/2011

come raggiungerlo?

Answer 1

Basta provare questo codice di esempio: -

import java.text.DateFormat; 
import java.text.SimpleDateFormat; 
import java.util.Calendar; 


public class Test { 

/** 
* Main Method 
*/ 
public static void main(String[] args) { 
    System.out.println(getDate(82233213123L, "dd/MM/yyyy hh:mm:ss.SSS")); 
} 


/** 
* Return date in specified format. 
* @param milliSeconds Date in milliseconds 
* @param dateFormat Date format 
* @return String representing date in specified format 
*/ 
public static String getDate(long milliSeconds, String dateFormat) 
{ 
    // Create a DateFormatter object for displaying date in specified format. 
    SimpleDateFormat formatter = new SimpleDateFormat(dateFormat); 

    // Create a calendar object that will convert the date and time value in milliseconds to date. 
    Calendar calendar = Calendar.getInstance(); 
    calendar.setTimeInMillis(milliSeconds); 
    return formatter.format(calendar.getTime()); 
} 
} 

Spero che questo aiuto ...

Answer 2

provare questo codice potrebbe aiutare, modificarlo base alle proprie esigenze

SimpleDateFormat format = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy"); 
Date d = format.parse(fileDate); 

Answer 3

È possibile costruire java.util.Date in millisecondi. E poi convertito in stringa con java.text.DateFormat.

Answer 4

Convertire il valore millisecondo nell'istanza Date e passarlo al formattatore scelto.

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); 
String dateString = formatter.format(new Date(dateInMillis))); 

Answer 5

ho finalmente trovato il codice normale che funziona per me

Long longDate = Long.valueOf(date); 

Calendar cal = Calendar.getInstance(); 
int offset = cal.getTimeZone().getOffset(cal.getTimeInMillis()); 
Date da = new Date(); 
da = new Date(longDate-(long)offset); 
cal.setTime(da); 

String time =cal.getTime().toLocaleString(); 
//this is full string   

time = DateFormat.getTimeInstance(DateFormat.MEDIUM).format(da); 
//this is only time 

time = DateFormat.getDateInstance(DateFormat.MEDIUM).format(da); 
//this is only date

public class LogicconvertmillistotimeActivity extends Activity { 
    /** Called when the activity is first created. */ 
    EditText millisedit; 
     Button millisbutton; 
     TextView millistextview; 
     long millislong; 
     String millisstring; 
     int millisec=0,sec=0,min=0,hour=0; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     millisedit=(EditText)findViewById(R.id.editText1); 
     millisbutton=(Button)findViewById(R.id.button1); 
     millistextview=(TextView)findViewById(R.id.textView1); 
     millisbutton.setOnClickListener(new View.OnClickListener() {    
      @Override 
      public void onClick(View v) { 
       millisbutton.setClickable(false); 
       millisec=0; 
       sec=0; 
       min=0; 
       hour=0; 
       millisstring=millisedit.getText().toString().trim(); 
       millislong= Long.parseLong(millisstring); 
       Calendar cal = Calendar.getInstance(); 
       SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss"); 
       if(millislong>1000){ 
        sec=(int) (millislong/1000); 
        millisec=(int)millislong%1000; 
        if(sec>=60){ 
         min=sec/60; 
         sec=sec%60; 
        } 
        if(min>=60){ 
         hour=min/60; 
         min=min%60; 
        } 
       } 
       else 
       { 
        millisec=(int)millislong; 
       } 
       cal.clear(); 
       cal.set(Calendar.HOUR_OF_DAY,hour); 
       cal.set(Calendar.MINUTE,min); 
       cal.set(Calendar.SECOND, sec); 
       cal.set(Calendar.MILLISECOND,millisec); 
       String DateFormat = formatter.format(cal.getTime()); 
//    DateFormat = ""; 
       millistextview.setText(DateFormat); 

      } 
     }); 
    } 
} 

Answer 7

public static String convertDate(String dateInMilliseconds,String dateFormat) { 
    return DateFormat.format(dateFormat, Long.parseLong(dateInMilliseconds)).toString(); 
} 

chiamare questa funzione

convertDate("82233213123","dd/MM/yyyy hh:mm:ss"); 

Answer 8

DateFormat.getDateInstance().format(dateInMS); 

Answer 9

breve ed efficace:

DateFormat.getDateTimeInstance().format(new Date(myMillisValue)) 

Answer 10

public static Date getDateFromString(String date) { 

    Date dt = null; 
    if (date != null) { 
     for (String sdf : supportedDateFormats) { 
      try { 
       dt = new Date(new SimpleDateFormat(sdf).parse(date).getTime()); 
       break; 
      } catch (ParseException pe) { 
       pe.printStackTrace(); 
      } 
     } 
    } 
    return dt; 
} 

public static Calendar getCalenderFromDate(Date date){ 
    Calendar cal =Calendar.getInstance(); 
    cal.setTime(date);return cal; 

} 
public static Calendar getCalenderFromString(String s_date){ 
    Date date = getDateFromString(s_date); 
    Calendar cal = getCalenderFromDate(date); 
    return cal; 
} 

public static long getMiliSecondsFromString(String s_date){ 
    Date date = getDateFromString(s_date); 
    Calendar cal = getCalenderFromDate(date); 
    return cal.getTimeInMillis(); 
} 

Answer 11

public static String toDateStr(long milliseconds, String format) 
{ 
    Date date = new Date(milliseconds); 
    SimpleDateFormat formatter = new SimpleDateFormat(format, Locale.US); 
    return formatter.format(date); 
}
