我想在Android中获取当前时间。它应该显示为下午 2:30，我想将其存储在数据库中。我搜索了很多。但我不知道该怎么做。我怎样才能做到这一点？

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);

String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());

// textView is the TextView view that should display it
textView.setText(currentDateTimeString);

我在下面得到了完美的时间......

 String Time = java.text.DateFormat.**getTimeInstance()**.format(new Date()); 
 //and for to get date try it as below
 String date_L = java.text.DateFormat.**getDateInstance()**.format(new Date());

要获得 12 小时格式的时间，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);

还可以使用以下整数获取小时、分钟和秒：

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

以下方法以指定日期格式为您提供当前日期和时间

 /**
         * 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()

你可以通过 Date dt = new Date();

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

并且为了存储在数据库中，请阅读 sqlite 教程here

很简单，您可以剖析时间以获取当前时间的单独值，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);

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;

或查看本教程。

你可以使用：

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

日历中有很多常量可以满足您的一切需求。

SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");
Calendar c = Calendar.getInstance();
Date date = Calendar.getInstance().getTime();
String sDate = format.format(date);//31-12-9999
int mYear = c.get(Calendar.YEAR);//9999
int mMonth = c.get(Calendar.MONTH);
mMonth = mMonth + 1;//12
int hrs = c.get(Calendar.HOUR_OF_DAY);//24
int min = c.get(Calendar.MINUTE);//59
