android 中 系统日期时间的获取
- 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()));
- 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.
