txtViewDate.setText(\"Today is \" +
              


        

Answer 1

        Date userDob = new SimpleDateFormat("yyyy-MM-dd").parse(dob);
        Date today = new Date();
        long diff =  today.getTime() - userDob.getTime();
        int numOfDays = (int) (diff / (1000 * 60 * 60 * 24));
        int hours = (int) (diff / (1000 * 60 * 60));
        int minutes = (int) (diff / (1000 * 60));
        int seconds = (int) (diff / (1000));
