Android Convert DateTime to EEE, d MMM yyyy

I am trying to convert the following data time to EEE, d MMM yyyy format but kept getting Unparsable date format. Can some one please help. I couldn't find anything on the web that helped.
Here is the code
String datestr = "2017-01-12T00:00:00Z";
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z", Locale.US);
Date convertedDateStart = new Date();
try {
convertedDateStart = dateFormat.parse(datestr);
camp_new.startdate = convertedDateStart;
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Any help wound be greatly appreciated. Thanks in advance

The date string "2017-01-12T00:00:00Z" cannot be parsed with your format "EEE, d MMM yyyy HH:mm:ss Z"; the fields are the wrong type or in the wrong place.
The format for your datestr "2017-01-12T00:00:00Z" should be:
yyyy-MM-dd'T'HH:mm:ssZ
You need to initialize the SimpleDateFormat with this format to parse datestr.
The format "EEE, d MMM yyyy HH:mm:ss Z" would parse a date that looks like
Thu, 1 Jan 2017 00:00:00 Z
Read the docs to understand the difference between parse() and format().

You have to parse it first, store it as a Date object and then use another SimpleDateFormat to format in the desired way.
String datestr = "2017-01-12T00:00:00Z";
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.US);
SimpleDateFormat dateFormat2 = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z", Locale.US);
Date date = dateFormat.parse(datestr);
String convertedDateStart = dateFormat2.format(date);

Well This will Work For you if you want to FORMAT and get a Date String with that format..
String datestr = "2017-01-12T00:00:00Z";
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US);
try {
date = dateFormat.parse(datestr);
} catch (ParseException e) {
e.printStackTrace();
}
dateFormat = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z", Locale.US);
datestr = dateFormat.format(date);
System.out.println(datestr);
This will give you Thu, 12 Jan 2017 00:00:00 +0430 Date String.

Parsing date using SimpleDateFormat to get Time

I am working on an Android application in which I need to parse my date to get my time. I am getting parsing exception when I am using my below code.
Here is the code:
SimpleDateFormat parseFormat = new SimpleDateFormat("dd MM hh:mm:ss yyyy");
SimpleDateFormat printFormat = new SimpleDateFormat("h:mm:ss");
Date date;
try { //selectedDateTime = Fri Jan 15 09:30:44 GMT+04:00 2016
date = parseFormat.parse(selectedDateTime+"");
System.out.println(printFormat.format(date));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Here is the exception:
java.text.ParseException: Unparseable date: "Fri Jan 15 09:30:00 GMT+04:00 2016" (at offset 0)

SimpleDateFormat parserSDF=new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Your formatting is off, try this.

Your Strings are wrong. The correct ones are:
SimpleDateFormat parseFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy");
SimpleDateFormat printFormat = new SimpleDateFormat("HH:mm:ss");

I guess your initial date format is wrong. Can you share the value of selectedDateTime.
I guess it in different format (as per your comment) like Fri Jan 15 09:30:44 GMT+04:00 2016
If so please try this code
SimpleDateFormat parseFormat = new SimpleDateFormat("E MM dd hh:mm:ss z yyyy");
SimpleDateFormat printFormat = new SimpleDateFormat("h:mm:ss");
Date date;
try { //selectedDateTime = Fri Jan 15 09:30:44 GMT+04:00 2016
date = parseFormat.parse(selectedDateTime+"");
System.out.println(printFormat.format(date));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

update
try {
String dateTest = "Fri Jan 15 09:30:00 GMT+04:00 2016";
SimpleDateFormat formatter = new SimpleDateFormat(
"EEE MMM dd hh:mm:ss zzz yyyy");
java.util.Date d = (java.util.Date) formatter.parse(dateTest);
System.out.println("" + d);
SimpleDateFormat print = new SimpleDateFormat("hh:mm:ss");
System.out.println(print.format(d));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
output
Fri Jan 15 11:00:00 IST 2016
11:00:00
Following code can help you understand how exactly formatting syntax change for date formatting
Calendar calendar = Calendar.getInstance();
System.out.println("Date: \t"+calendar.getTimeInMillis());
String dateAsText_ = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(Long.parseLong(""+calendar.getTimeInMillis())));
Date date = new Date(Long.parseLong(""+calendar.getTimeInMillis()));
System.out.println(""+dateAsText_);
SimpleDateFormat ft = new SimpleDateFormat ("dd-MMM-yyyy");
System.out.println(""+ft.format(date));
SimpleDateFormat time_ft = new SimpleDateFormat ("hh:mm aa");
System.out.println(""+time_ft.format(date));
Output
Date: 1452766759531
2016-01-14 15:49:19

Simple date formatting giving wrong time

I am trying to parse a String to a Date and it giving me right date where as time is wrong.
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm aaa");
try {
Date date = formatter.parse("2015-08-20 05:00 AM");
Log.e("date", date+""); // Logcat printing Thu Aug 20 00:00:00 GMT+05:30 2015
} catch (ParseException e) {
Log.e("Error",e.toString());
}
As you can see irrespective of the time every time parsed date time showing 00:00:00
What I want is Thu Aug 20 05:00:00 GMT+05:30 2015

It seems the problem was that your pattern String specified am/pm, but was using uppercase H's for the hour characters. These indicate a 24-hour clock, which obviously doesn't use am/pm. Change the hour characters to lowercase h's, which indicate the hour in am/pm (0-11).
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm aaa");
The docs for SimpleDateFormat explain the various acceptable pattern characters.

Try below code
SimpleDateFormat format = new SimpleDateFormat("E, dd MMM yyyy hh:mm:ss z");
String dateToStr = format.format(new Date());
System.out.println("dateToStr=>" + dateToStr);
try {
Date strToDate = format.parse(dateToStr);
System.out.println("strToDate=>" + strToDate);
} catch (ParseException e) {
e.printStackTrace();
}

Maybe its related to time zone issues, at what time zone is your input?, i'd suggest to make sure your paramater is on UTC timezone and then using formatter like this :
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm aaa");
formatter .setTimeZone(TimeZone.getTimeZone("UTC"));

Try this code you missed some lines of code
SimpleDateFormat mFormatter = new SimpleDateFormat("yyyy-MM-dd hh:mm aa", Locale.getDefault());
mFormatter.setTimeZone(TimeZone.getTimeZone("India"));
Date startDate = mFormatter.parse("2015-08-20 05:00 AM");
This code working fine for me.

Date format not working properly in Android

I am working on Android application in which I am saving and getting date from ORMLITE. I am using SimpleDateFormat for the formatting of the desire date, but except this pattern yyyy-MM-dd HH:mm it is not formatting it. My current date from server with desired dates with code is given below:
try {//EEEE , MMMM dd , yyyy hh:mm a
SimpleDateFormat mDBSDF = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
if(cursor.getString(cursor.getColumnIndex("mLastMessageDate"))==null){//.equals("") ||cursor.getString(cursor.getColumnIndex("mLastMessageDate")).toString()==null){
mTxtLastMessageDate.setText("");
mTxtLastMessageLabel.setText("");
}else{
mTxtLastMessageDate.setText(mDBSDF.parse(cursor.getString(cursor.getColumnIndex("mLastMessageDate"))).toString());
}
}catch(Exception ex) {
ex.printStackTrace();
}
This is my server date:
2015-04-28 12:57:04.000297
After using above format i am getting this:
Tue Apr 28 12:57:04 GMT+04:00 2015
I want the pattern like this:
Tuesday, April 28, 2015 1:00 pm
Except above yyyy-MM-dd HH:mm format even if i am changing "-" to "," it is not working without any error

SimpleDateFormat.parse(String) returns a Date not a formatted String.
Use SimpleDateFormat.format(Date) instead.

Try this to format the date and time...
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
Date date = new Date();
System.out.println(dateFormat.format(date));

Try this base on your requirement.
Input date as string
protected String dateFormat(String sqlDate) {
String strDate = "";
java.util.Date utilDate;
SimpleDateFormat sqlDateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");//input format
try {
Calendar calTempDate = Calendar.getInstance();
calTempDate.setFirstDayOfWeek(Calendar.MONDAY);
utilDate = sqlDateFormat.parse(sqlDate);
calTempDate.setTime(utilDate);
strDate = new SimpleDateFormat("EEEE MMMM dd,yyyy HH:mm a")
.format(calTempDate.getTime());//output format
} catch (Exception e) {
e.printStackTrace();
}
return strDate;
}

You can use this code to find out your solution.
SimpleDateFormat fromdateformate=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
Date date=fromdateformate.parse("2015-04-28 12:57:04.000297");
SimpleDateFormat todtaeFormate=new SimpleDateFormat("EEEE MMMM yyyy hh:mm aa");
String finaldate= todtaeFormate.format(date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

how to convert date format in android

I am getting date into string in YYYY/MM/DD HH:MM:SS format.I want to change it into the mm/dd/yyyy HH:mm:ss and also it will show AM and PM how can I do this.please help me
Thank you

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);

You can use the SimpleDateFormat for the same kinds of any date operations.
SimpleDateFormat sourceFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
SimpleDateFormat DesiredFormat = new SimpleDateFormat("MM/dd/yyyy HH:MM:SS a");
// 'a' for AM/PM
Date date = sourceFormat.parse("2012/12/31 03:20:20");
String formattedDate = DesiredFormat.format(date.getTime());
// Now formattedDate have current date/time
Toast.makeText(this, formattedDate, Toast.LENGTH_SHORT).show();

just use the Time class. Try something similar to this.
Time time = new Time();
time.set(Long.valueOf(yourTimeString));
If you really need a Date object just try this.
Date date = new Date(Long.parse(yourTimeString));

Use android.text.format.Time to the conversion. You can pass the time as text and it will return you the time in desired format by using timeInstance.format("");
you need to provide formatter.
Refer to following:
Time : http://developer.android.com/reference/android/text/format/Time.html
Formatter: http://pubs.opengroup.org/onlinepubs/007908799/xsh/strftime.html
you can use any combination of formatter string to work with it :)

you can use SimpleDateFormat or DateFormat for this here is the example
SimpleDateFormat gsdf = new SimpleDateFormat("YYYY/MM/DD HH:mm:ss");
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a");
try{
Date d = gsdf.parse("2011/12/13 16:17:00");
System.out.println("new date format " + sdf.format(d));
}catch(Exception){
// handle exception if parse time or another by cause
}

public static String getFormatedDate(String strDate, String sourceFormate,
String destinyFormate) {
SimpleDateFormat df;
df = new SimpleDateFormat(sourceFormate);
Date date = null;
try {
date = df.parse(strDate);
} catch (ParseException e) {
e.printStackTrace();
}
df = new SimpleDateFormat(destinyFormate);
return df.format(date);
}
and use like
getFormatedDate(strDate,
"yyyy-MM-dd HH:mm:ss", "mm/dd/yyyy")
