您应该根据新的API使用calendar类。Date类现在已弃用。

Calendar cal = Calendar.getInstance();

String date = "" + cal.get(Calendar.DATE) + "-" + (cal.get(Calendar.MONTH)+1) + "-" + cal.get(Calendar.YEAR);

String time = "" + cal.get(Calendar.HOUR_OF_DAY) + ":" + cal.get(Calendar.MINUTE);

你可以通过这个函数得到你的当地时间和GMT时间

public String getCurrentDate() {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy MMM dd hh:mm a zzz");
    Date date = new Date();
    sdf.setTimeZone(TimeZone.getTimeZone("GMT+6:00"));
    return sdf.format(date);
}

Time now = new Time();
now.setToNow();

试试这个对我也有用。

对于那些可能更喜欢定制格式的人，您可以使用:

DateFormat df = new SimpleDateFormat("EEE, d MMM yyyy, HH:mm");
String date = df.format(Calendar.getInstance().getTime());

然而，你可以有DateFormat模式，如:

"yyyy.MM.dd G 'at' HH:mm:ss z" ---- 2001.07.04 AD at 12:08:56 PDT
"hh 'o''clock' a, zzzz" ----------- 12 o'clock PM, Pacific Daylight Time
"EEE, d MMM yyyy HH:mm:ss Z"------- Wed, 4 Jul 2001 12:08:56 -0700
"yyyy-MM-dd'T'HH:mm:ss.SSSZ"------- 2001-07-04T12:08:56.235-0700
"yyMMddHHmmssZ"-------------------- 010704120856-0700
"K:mm a, z" ----------------------- 0:08 PM, PDT
"h:mm a" -------------------------- 12:08 PM
"EEE, MMM d, ''yy" ---------------- Wed, Jul 4, '01

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Calendar cal = Calendar.getInstance();
    System.out.println("time => " + dateFormat.format(cal.getTime()));

    String time_str = dateFormat.format(cal.getTime());

    String[] s = time_str.split(" ");

    for (int i = 0; i < s.length; i++) {
         System.out.println("date  => " + s[i]);
    }

    int year_sys = Integer.parseInt(s[0].split("/")[0]);
    int month_sys = Integer.parseInt(s[0].split("/")[1]);
    int day_sys = Integer.parseInt(s[0].split("/")[2]);

    int hour_sys = Integer.parseInt(s[1].split(":")[0]);
    int min_sys = Integer.parseInt(s[1].split(":")[1]);

    System.out.println("year_sys  => " + year_sys);
    System.out.println("month_sys  => " + month_sys);
    System.out.println("day_sys  => " + day_sys);

    System.out.println("hour_sys  => " + hour_sys);
    System.out.println("min_sys  => " + min_sys);

如果你想以特定的模式获取日期和时间，你可以使用以下命令:

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault());
String currentDateandTime = sdf.format(new Date());

Or,

日期:

String currentDate = new SimpleDateFormat("dd-MM-yyyy", Locale.getDefault()).format(new Date());

时间:

String currentTime = new SimpleDateFormat("HH:mm:ss", Locale.getDefault()).format(new Date());
