Question

I have a date value in this format: yyyy-MM-dd kk:mm:ss

So from this line data = params.getString("data"); i get the date I have set before in another activity.
So with a button click I need to add + 10 minutes to the date value.

I do know its through the value.put("...",...); but as I don’t want to change the DATE only the TIME of the value. How should do I do it?

Answer 1

Use an instance of Calendar:

 SimpleDateFormat currentDate = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss");

 Calendar c = Calendar.getInstance();
 c.setTime(currentDate.parse(data)); // your date value
 c.add(Calendar.MINUTE,10);
 newDate = c.getTime()
