Date Format Conversion Android

How to convert Date to a particular format in android?

This is modified code that you should use:

String date="Mar 10, 2016 6:30:00 PM";
SimpleDateFormat spf=new SimpleDateFormat("MMM dd, yyyy hh:mm:ss aaa");
Date newDate=spf.parse(date);
spf= new SimpleDateFormat("dd MMM yyyy");
date = spf.format(newDate);
System.out.println(date);

Use hh for hours in order to get correct time.

Java 8 and later

Java 8 introduced new classes for time manipulation, so use following code in such cases:

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMM dd, yyyy h:mm:ss a");
    LocalDateTime dateTime = LocalDateTime.parse(date, formatter);
    DateTimeFormatter formatter2 = DateTimeFormatter.ofPattern("dd MMM yyyy");
    System.out.println(dateTime.format(formatter2));

Use h for hour format, since in this case hour has only one digit.

Date format conversion Android

try this

SimpleDateFormat form = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
java.util.Date date = null;
try 
{
    date = form.parse("2011-03-27T09:39:01.607");
}
catch (ParseException e) 
{

    e.printStackTrace();
}
SimpleDateFormat postFormater = new SimpleDateFormat("MMMMM dd, yyyy");
String newDateStr = postFormater.format(date);

now newDateStr = March 27, 2011;

How do I change date time format in Android?

Here is working code

public String parseDateToddMMyyyy(String time) {
    String inputPattern = "yyyy-MM-dd HH:mm:ss";
    String outputPattern = "dd-MMM-yyyy h:mm a";
    SimpleDateFormat inputFormat = new SimpleDateFormat(inputPattern);
    SimpleDateFormat outputFormat = new SimpleDateFormat(outputPattern);

    Date date = null;
    String str = null;

    try {
        date = inputFormat.parse(time);
        str = outputFormat.format(date);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return str;
}

how to convert date format in android

To get AM PM and 12 hour date format use hh:mm:ss a as string formatter WHERE hh is for 12 hour format and a is for AM PM format.

Note: HH is for 24 hour and hh is for 12 hour date format

SimpleDateFormat formatter = new SimpleDateFormat("mm/dd/yyyy hh:mm:ss a");
            String newFormat = formatter.format(testDate);

Example

String date = "2011/11/12 16:05:06";
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/mm/dd HH:MM:SS");
        Date testDate = null;
        try {
            testDate = sdf.parse(date);
        }catch(Exception ex){
            ex.printStackTrace();
        }
        SimpleDateFormat formatter = new SimpleDateFormat("mm/dd/yyyy hh:mm:ss a");
        String newFormat = formatter.format(testDate);
        System.out.println(".....Date..."+newFormat);

Convert date format to different date format in android

You mixed:

mm  =  minutes

with

MM  =  months

So you have to change from:

SimpleDateFormat spf = new SimpleDateFormat("mm/dd/yy");

in to:

SimpleDateFormat spf = new SimpleDateFormat("MM/dd/yy");

When you print before changes:

System.out.println(newDate);

You will receive:

 Tue Jan 07 00:04:00 WET 2020
               /\
               ||
               ||
          your minutes

Full working example

(with better naming)

try {
    String inputDate = "04/07/20";
    SimpleDateFormat inputFormat = new SimpleDateFormat("MM/dd/yy");

    Date parsedDate = inputFormat.parse(inputDate);
    SimpleDateFormat outputFormat = new SimpleDateFormat("dd MMMM, yy");

    inputDate = outputFormat.format(parsedDate);
    System.out.println(inputDate);
} catch (Exception e) {
    e.printStackTrace();
}

How to convert 2021-07-06T19:27:46.811+0530 format to d MMM yyyy, hh:mm aaa this format in android

Android change date format from String to Date and Time separated

A more robust way of accomplishing this task is provided below with a code example.

    String initialStringDate = "2019-01-27T09:27:37Z";
    Locale us = new Locale("US");
    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", us);
    try {
        Date date = format.parse(initialStringDate);
        String stringDate = new SimpleDateFormat("yyyy/MM/dd", us).format(date);
        String stringTime = new SimpleDateFormat("HH:mm", us).format(date);

        String finalDateTime = stringDate.concat(" ").concat(stringTime);

        Log.i("Date_and_Time", "" + finalDateTime);
    } catch (ParseException e) {
        e.printStackTrace();
    }

Note: With the provided above code you will be able to even localize your date and time.

How Convert String to datetime in android

You can use SimpleDateFormat for parsing String to Date.

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
try {
  Date d = sdf.parse("20130526160000");
} catch (ParseException ex) {
  Log.v("Exception", ex.getLocalizedMessage());
}

Now you can convert your Date object back to String in your required format as below.

sdf.applyPattern("dd MMM yyyy hh:mm");
System.out.println(sdf.format(d));

How to format date and time in Android?

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.
