Android - problem parsing date

I am using the following piece of code to parse a date -

DateFormat dateFormatIn = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.S'Z'");
Strin开发者_如何转开发g ts = "2011-06-15T17:34:09.291Z";
String timestamp = dateFormatIn.format(ts);

It throws me an IllegalArgumentException. Any idea what is the right way to go about it?

DateFormat.format() expects a Date as parameter and not a String.

U need to use DateFormat.parse() to get the Date
