How to format correctly according to the device configuration date and time when having a year, month, day, hour and minute?

Use the standard Java DateFormat class.
For example to display the current date and time do the following:
Date date = new Date(location.getTime());
DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
mTimeText.setText("Time: " + dateFormat.format(date));
You can initialise a Date object with your own values, however you should be aware that the constructors have been deprecated and you should really be using a Java Calendar object.
You can use DateFormat. Result depends on default Locale of the phone, but you can specify Locale too :
https://developer.android.com/reference/java/text/DateFormat.html
This is results on a
DateFormat.getDateInstance().format(date)
FR Locale : 3 nov. 2017
US/En Locale : Jan 12, 1952
DateFormat.getDateInstance(DateFormat.SHORT).format(date)
FR Locale : 03/11/2017
US/En Locale : 12.13.52
DateFormat.getDateInstance(DateFormat.MEDIUM).format(date)
FR Locale : 3 nov. 2017
US/En Locale : Jan 12, 1952
DateFormat.getDateInstance(DateFormat.LONG).format(date)
FR Locale : 3 novembre 2017
US/En Locale : January 12, 1952
DateFormat.getDateInstance(DateFormat.FULL).format(date)
FR Locale : vendredi 3 novembre 2017
US/En Locale : Tuesday, April 12, 1952
DateFormat.getDateTimeInstance().format(date)
FR Locale : 3 nov. 2017 16:04:58
DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT).format(date)
FR Locale : 03/11/2017 16:04
DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.MEDIUM).format(date)
FR Locale : 03/11/2017 16:04:58
DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.LONG).format(date)
FR Locale : 03/11/2017 16:04:58 GMT+01:00
DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.FULL).format(date)
FR Locale : 03/11/2017 16:04:58 heure normale d’Europe centrale
DateFormat.getTimeInstance().format(date)
FR Locale : 16:04:58

Date and Time format explanation
EEE : Day ( Mon )
MMMM : Full month name ( December ) // MMMM February
MMM : Month in words ( Dec )
MM : Month ( 12 )
dd : Day in 2 chars ( 03 )
d: Day in 1 char (3)
HH : Hours ( 12 )
mm : Minutes ( 50 )
ss : Seconds ( 34 )
yyyy: Year ( 2020 ) //both yyyy and YYYY are same
YYYY: Year ( 2020 )
zzz : GMT+05:30
a : ( AM / PM )
aa : ( AM / PM )
aaa : ( AM / PM )
aaaa : ( AM / PM )
Here is the simplest way:
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss a", Locale.US);
String time = df.format(new Date());
and If you are looking for patterns, check this https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
Shortest way:
// 2019-03-29 16:11
String.format("%1$tY-%<tm-%<td %<tR", Calendar.getInstance())
%tR is short for %tH:%tM, < means to reuse last parameter(1$).
It is equivalent to String.format("%1$tY-%1$tm-%1$td %1$tH:%1$tM", Calendar.getInstance())
https://developer.android.com/reference/java/util/Formatter.html
Date format class work with cheat code to make date. Like
- M -> 7, MM -> 07, MMM -> Jul , MMMM -> July
- EEE -> Tue , EEEE -> Tuesday
- z -> EST , zzz -> EST , zzzz -> Eastern Standard Time
You can check more cheats here.
This code work for me!
Date d = new Date();
CharSequence s = android.text.format.DateFormat.format("MM-dd-yy hh-mm-ss",d.getTime());
Toast.makeText(this,s.toString(),Toast.LENGTH_SHORT).show();
Locale
To get date or time in locale format from milliseconds I used this:
Date and time
Date date = new Date(milliseconds);
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.SHORT, Locale.getDefault());
dateFormat.format(date);
Date
Date date = new Date(milliseconds);
DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.MEDIUM, Locale.getDefault());
dateFormat.format(date);
Time
Date date = new Date(milliseconds);
DateFormat dateFormat = DateFormat.getTimeInstance(DateFormat.SHORT, Locale.getDefault());
dateFormat.format(date);
You can use other date style and time style. More info about styles here.
I use it like this:
public class DateUtils {
static DateUtils instance;
private final DateFormat dateFormat;
private final DateFormat timeFormat;
private DateUtils() {
dateFormat = android.text.format.DateFormat.getDateFormat(MainApplication.context);
timeFormat = android.text.format.DateFormat.getTimeFormat(MainApplication.context);
}
public static DateUtils getInstance() {
if (instance == null) {
instance = new DateUtils();
}
return instance;
}
public synchronized static String formatDateTime(long timestamp) {
long milliseconds = timestamp * 1000;
Date dateTime = new Date(milliseconds);
String date = getInstance().dateFormat.format(dateTime);
String time = getInstance().timeFormat.format(dateTime);
return date + " " + time;
}
}
Try:
event.putExtra("startTime", "10/05/2012");
And when you are accessing passed variables:
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
Date date = formatter.parse(bundle.getString("startTime"));
It's too late but it may help to someone
DateFormat.format(format, timeInMillis);
here format is what format you need
ex: "HH:mm" returns 15:30
Date from type
EEE : Day ( Mon )
MMMM : Full month name ( December ) // MMMM February
MMM : Month in words ( Dec )
MM : Month ( 12 )
dd : Day in 2 chars ( 03 )
d: Day in 1 char (3)
HH : Hours ( 12 )
mm : Minutes ( 50 )
ss : Seconds ( 34 )
yyyy: Year ( 2020 ) //both yyyy and YYYY are same
YYYY: Year ( 2020 )
zzz : GMT+05:30
a : ( AM / PM )
aa : ( AM / PM )
aaa : ( AM / PM )
aaaa : ( AM / PM )
