import java.text.SimpleDateFormat; SimpleDateFormat formatter = new SimpleDateFormat ("yyyy年MM月dd日 HH:mm:ss "); Date curDate = new Date(System.currentTimeMillis());//获取当前时间 String str = formatter.format(curDate);
若要显示日期,可用‘E’字符,默认为英文,若要变为中文,可参考如下代码:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 E",Locale.CHINA);
也可以这样写:
df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA); System.out.println(df.format(new Date()));
2.获取Android小时制(24小时制还是12小时制):
ContentResolver cv = this.getContentResolver(); String strTimeFormat = android.provider.Settings.System.getString(cv, android.provider.Settings.System.TIME_12_24); if(strTimeFormat.equals("24")) { Log.i("activity","24"); }
Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE)
3.利用Calender获取时间:
Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE) Calendar c = Calendar.getInstance(); 取得系统日期:year = c.get(Calendar.YEAR) month = c.grt(Calendar.MONTH) day = c.get(Calendar.DAY_OF_MONTH) 取得系统时间:hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE)
4.利用Time获取时间:
Time t=new Time(); // or Time t=new Time("GMT+8"); 加上Time Zone资料。 t.setToNow(); // 取得系统时间。 int year = t.year; int month = t.month; int date = t.monthDay; int hour = t.hour; // 0-23 int minute = t.minute; int second = t.second;
注:Time取出的只有24小时制
