下面是一些获取时间和日期的方法:

public static void getCurrentTimeUsingDate() {
    Date date = new Date();
    String strDateFormat = "hh:mm:ss a";
    DateFormat dateFormat = new SimpleDateFormat(strDateFormat);
    String formattedDate= dateFormat.format(date);
    Toast.makeText(this, formattedDate, Toast.LENGTH_SHORT).show();
}

使用日历的时间

public static void getCurrentTimeUsingCalendar() {
    Calendar cal = Calendar.getInstance();
    Date date=cal.getTime();
    DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
    String formattedDate=dateFormat.format(date);
    Toast.makeText(this, formattedDate, Toast.LENGTH_SHORT).show();
}

当地时间日期

public static void getCurrentTime(){
    System.out.println("-----Current time of your time zone-----");
    LocalTime time = LocalTime.now();
    Toast.makeText(this, time, Toast.LENGTH_SHORT).show();
}

分区时间

public static void getCurrentTimeWithTimeZone(){
    Toast.makeText(this, "Current time of a different time zone using LocalTime", Toast.LENGTH_SHORT).show();

    ZoneId zoneId = ZoneId.of("America/Los_Angeles");
    LocalTime localTime=LocalTime.now(zoneId);
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
    String formattedTime=localTime.format(formatter);
    Toast.makeText(this,formattedTime , Toast.LENGTH_SHORT).show();
}

获取当前时间和日期的简单方法

import java.util.Calendar

Date currentTime = Calendar.getInstance().getTime();

试试这个

String mytime = (DateFormat.format("dd-MM-yyyy hh:mm:ss", new java.util.Date()).toString());

你可以通过以下方法获取日期:

Time t = new Time(Time.getCurrentTimezone());
t.setToNow();
String date = t.format("%Y/%m/%d");

这将给你一个漂亮的表单结果，如这个例子:"2014/02/09"。

    ZoneId zoneId = ZoneId.of("America/Los_Angeles");
    LocalTime localTime=LocalTime.now(zoneId);
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
    String formattedTime=localTime.format(formatter);
    Toast.makeText(this,formattedTime , Toast.LENGTH_SHORT).show();
}

获取当前时间和日期的简单方法

import java.util.Calendar

Date currentTime = Calendar.getInstance().getTime();

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);

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);
}
