Change Date String Format in Android

Change String date format and set into TextView in Android?

Try like this:

String date ="29/07/13";
SimpleDateFormat input = new SimpleDateFormat("dd/MM/yy");
SimpleDateFormat output = new SimpleDateFormat("dd MMM yyyy");
try {
    oneWayTripDate = input.parse(date);                 // parse input 
    tripDate.setText(output.format(oneWayTripDate));    // format output
} catch (ParseException e) {
    e.printStackTrace();
}

It's a 2-step process: you first need to parse the existing String into a Date object. Then you need to format the Date object into a new String.

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.

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 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));

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.

Kotlin Android / Java String DateTime Format, API21

Parse it to LocalDateTime then format it:

LocalDateTime localDateTime = LocalDateTime.parse("2018-12-14T09:55:00");
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd.MM.yyyy HH:mm");
String output = formatter.format(localDateTime);

If this does not work with api21, you can use:

SimpleDateFormat parser = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
SimpleDateFormat formatter = new SimpleDateFormat("dd.MM.yyyy HH:mm");
String output = formatter.format(parser.parse("2018-12-14T09:55:00"));
