How to convert Date to a particular format in android?

You should parse() the String into Date and then format it into the desired format. You can use MMM dd, yyyy HH:mm:ss a format to parse the given String.

Here is the code snippet:

public static void main (String[] args) throws Exception
{
    String date = "Mar 10, 2016 6:30:00 PM";
    SimpleDateFormat spf = new SimpleDateFormat("MMM dd, yyyy hh:mm:ss a");
    Date newDate = spf.parse(date);
    spf = new SimpleDateFormat("dd MMM yyyy");
    String newDateString = spf.format(newDate);
    System.out.println(newDateString);
}

Output:

10 Mar 2016

conversion from string to date and date to string

String deliveryDate="2018-09-04";                       
SimpleDateFormat dateFormatprev = new SimpleDateFormat("yyyy-MM-dd");
Date d = dateFormatprev.parse(deliveryDate);
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE dd MMM yyyy");
String changedDate = dateFormat.format(d);

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.

You can use following method for this problem. We simply need to pass Current date format, required date format and Date String.

private String changeDateFormat(String currentFormat,String requiredFormat,String dateString){
    String result="";
    if (Strings.isNullOrEmpty(dateString)){
        return result;
    }
    SimpleDateFormat formatterOld = new SimpleDateFormat(currentFormat, Locale.getDefault());
    SimpleDateFormat formatterNew = new SimpleDateFormat(requiredFormat, Locale.getDefault());
    Date date=null;
    try {
        date = formatterOld.parse(dateString);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    if (date != null) {
        result = formatterNew.format(date);
    }
    return result;
}

This method will return Date String in format you require. In your case method call will be:

String date = changeDateFormat("MMM dd, yyyy hh:mm:ss a","dd MMM yyyy","Mar 10, 2016 6:30:00 PM");
