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);
可以获取当前的年月时分,也可以分开写:
SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String date = sDateFormat.format(new java.util.Date());
如果想获取当前的年月,则可以这样写(只获取时间或秒种一样):
Java代码
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM");
String date=sdf.format(new java.util.Date());
当然还有就是可以指定时区的时间(待):
df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA);
System.out.println(df.format(new Date()));
如何获取Android系统时间是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)
利用Calendar获取
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)
利用Time获取
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;
唯一不足是取出时间只有24小时模式.
