Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT+1:00"));
Date currentLocalTime = cal.getTime();
DateFormat date = new SimpleDateFormat("HH:mm a"); 
// you can get seconds by adding  "...:ss" to it
date.setTimeZone(TimeZone.getTimeZone("GMT+1:00")); 

String localTime = date.format(currentLocalTime);

To get the time in a 12 hour format try this code with "KK" instead of "HH". A full explanation of the symbols you can use are here.

要以 12 小时格式获取时间，请尝试使用“KK”而不是“HH”的代码。您可以使用的符号的完整说明在这里。

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT-4:00"));
     Date currentLocalTime = cal.getTime();
     DateFormat date = new SimpleDateFormat("KK:mm");
     date.setTimeZone(TimeZone.getTimeZone("GMT-4:00")); 
     String localTime = date.format(currentLocalTime); 

Also to get the hour, minutes and seconds as integers you can use:

还要将小时、分钟和秒作为整数，您可以使用：

int currentHour = cal.get(Calendar.HOUR);
int currentMinutes = cal.get(Calendar.MINUTE);
int currentSeconds = cal.get(Calendar.SECOND);

Following method gives you to current date and time in specified date format

以下方法为您提供指定日期格式的当前日期和时间

 /**
         * getCurrentTime() it will return system time
         * 
         * @return
         */
        public static String getCurrentTime() {     
           //date output format
            DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
            Calendar cal = Calendar.getInstance();
            return dateFormat.format(cal.getTime());
        }// end of getCurrentTime()

Easy, you can dissect the time to get separate values for current time, as follows:

很简单，您可以剖析时间以获得当前时间的单独值，如下所示：

Calendar cal = Calendar.getInstance(); 

  int millisecond = cal.get(Calendar.MILLISECOND);
  int second = cal.get(Calendar.SECOND);
  int minute = cal.get(Calendar.MINUTE);
        //12 hour format
  int hour = cal.get(Calendar.HOUR);
        //24 hour format
  int hourofday = cal.get(Calendar.HOUR_OF_DAY);

You can get time via Date dt = new Date();

你可以通过 Date dt = new Date();

        int hours = dt.getHours();
        int minutes = dt.getMinutes();
        int seconds = dt.getSeconds();

use digital clock widget when you want a current time:

当您需要当前时间时使用数字时钟小部件：

Calendar mCalendar;
private final static String m12 = "h:mm aa";
private final static String m24 = "k:mm";
private FormatChangeObserver mFormatChangeObserver;

private Runnable mTicker;
private Handler mHandler;

private boolean mTickerStopped = false;

String mFormat;

or check this tutorial.

You could use:

你可以使用：

Calendar c = Calendar.getInstance(); 
int seconds = c.get(Calendar.SECOND);

There are plenty of constants in Calendar for everything you need.

日历中有大量常量可满足您的所有需求。
