how to get a formatted date as milliseconds?

I have a formatted date from sqllite database, to use this in a graph view I need to format it in a long number.

The format is:

2012-07-11 10:55:21

h

Answer 1

Use date.getTime()

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd, HH:mm:ss");
formatter.setLenient(false);


String oldTime = "2012-07-11 10:55:21";
Date oldDate = formatter.parse(oldTime);
long oldMillis = oldDate.getTime();
