在Android中设置日期和所需时间

Question

我想在我的Android应用程序中设置日期和时间.日期应为今天的日期,但默认情况下,时间应设置为文本字段中的上午6:00.我已阅读了很多链接,但大部分都显示了今天的时间和日期(例如:2016-03-28 11:53:55).

 String timetxt1 = "06:00:00";
 Date datetxt1 = null;;
 try {
     datetxt1 = simpleDateFormat.parse(timetxt1);
 } catch (ParseException e) {
     e.printStackTrace();
 }
 Calendar selectedDate1 = Calendar.getInstance();
 selectedDate1.setTime(datetxt1);

 edittxt.setText(dateFormatter.format(selectedDate1.getTime()));

Answer 1

 Date date = new Date();
 Calendar calendar = Calendar.getInstance();
 calendar.setTime(date);
 calendar.set(Calendar.HOUR_OF_DAY, 6);// for 6 hour
 calendar.set(Calendar.MINUTE, 0);// for 0 min
 calendar.set(Calendar.SECOND, 0);// for 0 sec
 System.out.println(calendar.getTime());// print 'Mon Mar 28 06:00:00 ALMT 2016'
