final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);

textView.setText("" + mDay + "-" + mMonth + "-" + mYear);

final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);

textView.setText("" + mDay + "-" + mMonth + "-" + mYear);

实际上，使用time . getcurrenttimezone()在设备上设置当前时区更安全，否则您将获得UTC的当前时间。

Time today = new Time(Time.getCurrentTimezone());
today.setToNow();

然后，你可以得到你想要的所有日期字段，例如:

textViewDay.setText(today.monthDay + "");             // Day of the month (1-31)
textViewMonth.setText(today.month + "");              // Month (0-11)
textViewYear.setText(today.year + "");                // Year 
textViewTime.setText(today.format("%k:%M:%S"));  // Current time

更新

正如许多人指出的那样，谷歌说这个类有一些问题，不应该再使用了:

This class has a number of issues and it is recommended that GregorianCalendar is used instead. Known issues: For historical reasons when performing time calculations all arithmetic currently takes place using 32-bit integers. This limits the reliable time range representable from 1902 until 2037.See the wikipedia article on the Year 2038 problem for details. Do not rely on this behavior; it may change in the future. Calling switchTimezone(String) on a date that cannot exist, such as a wall time that was skipped due to a DST transition, will result in a date in 1969 (i.e. -1, or 1 second before 1st Jan 1970 UTC). Much of the formatting / parsing assumes ASCII text and is therefore not suitable for use with non-ASCII scripts.

对于自定义的时间和日期格式:

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZZZZZ",Locale.ENGLISH);
String cDateTime = dateFormat.format(new Date());

输出格式如下:

2015 - 06 - 18 - t10:15:56凌晨

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);
}

你可以使用以下代码:

Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String strDate = sdf.format(c.getTime());

输出:

2014-11-11 00:47:55

您还可以从这里获得SimpleDateFormat的更多格式化选项。
