Convert string Date into timestamp in Android?

Question

I want to convert my date (which is in String format), e.g. 13-09-2011, into Timestamp. I used below code but I got the 2011-09-13 00:00:00.0 as a result. But I want Timestamp like,1312828200000 format.

I cannot understand how to convert that.

My code:

String str_date="13-09-2011"; DateFormat formatter ;  Date date ;  formatter = new SimpleDateFormat("dd-MM-yyyy"); date = (Date)formatter.parse(str_date);  java.sql.Timestamp timeStampDate = new Timestamp(date.getTime()); System.out.println("Today is " +timeStampDate); 

Answer 1

If you use getTime() of Date object you will get time in millisecond. No need to use Timestamp to get your result.

String str_date="13-09-2011"; DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy"); Date date = (Date)formatter.parse(str_date);  System.out.println("Today is " +date.getTime()); 

The above code will print something like 1312828200000 you need and this is long value.

String str_date=month+"-"+day+"-"+yr; DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); Date date = (Date)formatter.parse(str_date);  long output=date.getTime()/1000L; String str=Long.toString(output); long timestamp = Long.parseLong(str) * 1000;
