I wrote the following code
Date d = new Date();
CharSequence s = DateFormat.format("MMMM d, yyyy ", d.getTime());
But is asking me parameter, I want current date in string format,
like
28-Dec-2011
so that I can set over TextView
,
explain a bit, if you think something is necessary, I am new to Android Development.
You can use the SimpleDateFormat
class for formatting date in your desired format.
Just check this link where you get an idea for your example.
For example:
String dateStr = "04/05/2010";
SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yyyy");
Date dateObj = curFormater.parse(dateStr);
SimpleDateFormat postFormater = new SimpleDateFormat("MMMM dd, yyyy");
String newDateStr = postFormater.format(dateObj);
Update:
The detailed example is here, I would suggest you go through this example and understand the concept of SimpleDateFormat class.
Final Solution:
Date c = Calendar.getInstance().getTime();
System.out.println("Current time => " + c);
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = df.format(c);
Its simple one line code for get current Date in this yyyy-MM-dd format you can use your format that you want :
String date = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault()).format(new Date());
This is nothing to do with android as it is java based so you could use
private String getDateTime() {
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
return dateFormat.format(date);
}
public String giveDate() {
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("EEE, MMM d, yyyy");
return sdf.format(cal.getTime());
}
try this,
SimpleDateFormat timeStampFormat = new SimpleDateFormat("yyyyMMddHHmmssSS");
Date myDate = new Date();
String filename = timeStampFormat.format(myDate);
CharSequence s = DateFormat.getDateInstance().format("MMMM d, yyyy ");
You need an instance first
Works like a charm and converts to String as a bonus ;)
SimpleDateFormat currentDate = new SimpleDateFormat("dd/MM/yyyy");
Date todayDate = new Date();
String thisDate = currentDate.format(todayDate);
String date = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
// import Date class as java.util
The below code displays the both time and date
Calendar cal = Calendar.getInstance();
cal.getTime().toString();
Calendar cal = Calendar.getInstance();
Calendar dt = Calendar.getInstance();
dt.clear();
dt.set(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),cal.get(Calendar.DATE));
return dt.getTime();
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String date = df.format(Calendar.getInstance().getTime());
A simple tweak to Paresh's solution:
Date date = Calendar.getInstance().getTime();
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = df.format(date);
You can use following code to get a date in the format you want.
String date = String.valueOf(android.text.format.DateFormat.format("dd-MM-yyyy", new java.util.Date()));
Date c = Calendar.getInstance().getTime();
System.out.println("Current time => " + c);
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = df.format(c);
This one is the best answer...
Calendar c = Calendar.getInstance();
int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + (month + 1) + "/" + year;
Log.i("TAG", "--->" + date);
I am providing the modern answer.
java.time and ThreeTenABP
To get the current date:
LocalDate today = LocalDate.now(ZoneId.of("America/Hermosillo"));
This gives you a LocalDate
object, which is what you should use for keeping a date in your program. A LocalDate
is a date without time of day.
Only when you need to display the date to a user, format it into a string suitable for the user’s locale:
DateTimeFormatter userFormatter
= DateTimeFormatter.ofLocalizedDate(FormatStyle.LONG);
System.out.println(today.format(userFormatter));
When I ran this snippet today in US English locale, output was:
July 13, 2019
If you want it shorter, specify FormatStyle.MEDIUM
or even FormatStyle.SHORT
. DateTimeFormatter.ofLocalizedDate
uses the default formatting locale, so the point is that it will give output suitable for that locale, different for different locales.
If your user has very special requirements for the output format, use a format pattern string:
DateTimeFormatter userFormatter = DateTimeFormatter.ofPattern(
"d-MMM-u", Locale.forLanguageTag("ar-AE"));

I am using and recommending java.time, the modern Java date and time API. DateFormat
, SimpleDateFormat
, Date
and Calendar
used in the question and/or many of the other answers, are poorly designed and long outdated. And java.time is so much nicer to work with.
Question: Can I use java.time on Android?
Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.
- In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
- In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
- On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from
org.threeten.bp
with subpackages.

- Java Specification Request (JSR) 310, where
java.time
was first described. - ThreeTen Backport project, the backport of
java.time
to Java 6 and 7 (ThreeTen for JSR-310). - ThreeTenABP, Android edition of ThreeTen Backport

The simplest way to get the current date in current locale (device locale!) :
String currentDate = DateFormat.getDateInstance().format(Calendar.getInstance().getTime());
If you want to have the date in different styles use getDateInstance(int style)
:
DateFormat.getDateInstance(DateFormat.FULL).format(Calendar.getInstance().getTime());
Other styles: DateFormat.LONG
, DateFormat.DATE_FIELD
, DateFormat.DAY_OF_YEAR_FIELD
, etc. (use CTRL+Space to see all of them)
If you need the time too:
String currentDateTime = DateFormat.getDateTimeInstance(DateFormat.DEFAULT,DateFormat.LONG).format(Calendar.getInstance().getTime());
public static String getDateTime() {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMMM dd, yyyy HH:mm:ss", Locale.getDefault());
Date date = new Date();
return simpleDateFormat.format(date);
}
try with this link of code this is absolute correct answer for all cases all over date and time. or customize date and time as per need and requirement of app.

I wrote calendar app using CalendarView and it's my code:
CalendarView cal = (CalendarView) findViewById(R.id.calendar);
cal.setDate(new Date().getTime());
'calendar' field is my CalendarView. Imports:
import android.widget.CalendarView;
import java.util.Date;
I've got current date without errors.
This is the code i used:
Date date = new Date(); // to get the date
SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy"); // getting date in this format
String formattedDate = df.format(date.getTime());
text.setText(formattedDate);
I've already used this:
Date What_Is_Today=Calendar.getInstance().getTime();
SimpleDateFormat Dateformat = new SimpleDateFormat("dd-MM-yyyy");
String Today=Dateformatf.format(What_Is_Today);
Toast.makeText(this,Today,Toast.LENGTH_LONG).show();
at first I get time, then I declared a Simple Date Format (to get date like: 19-6-2018) then I use format to change date to string.
public static String getcurrentDateAndTime(){
Date c = Calendar.getInstance().getTime();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
String formattedDate = simpleDateFormat.format(c);
return formattedDate;
}
// String currentdate= getcurrentDateAndTime();
This is the code I used:
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
// Set current date into textview
tvDisplayDate.setText(new StringBuilder()
.append(month + 1).append("-") // Month is 0 based, add 1
.append(day).append("-")
.append(year).append(" Today is :" + thursday ) );
// Set current date into datepicker
dpResult.init(year, month, day, null);
