android 中 系統(tǒng)日期時(shí)間的獲取

1、[java]viewplaincopyprint1.imptjava.text.SimpleDateFmat2.3.SimpleDateFmatfmatter=newSimpleDateFmat(“yyyy年MM月dd日HH:mm:ss“)4.DatecurDate=newDate(System.currentTimeMillis())獲取當(dāng)前時(shí)間5.Stringstr=fmatter.fmat(curDate)可以獲取當(dāng)前的年月時(shí)分也

2、可以分開寫:[java]viewplaincopyprint1.SimpleDateFmatsDateFmat=newSimpleDateFmat(“yyyyMMddhh:mm:ss“)2.Stringdate=sDateFmat.fmat(newjava.util.Date())如果想獲取當(dāng)前的年月則可以這樣寫(只獲取時(shí)間或秒種一樣):Java代碼[java]viewplaincopyprint1.SimpleDateFmatsdf=

3、newSimpleDateFmat(“yyyyMM“)2.Stringdate=sdf.fmat(newjava.util.Date())當(dāng)然還有就是可以指定時(shí)區(qū)的時(shí)間(待):[java]viewplaincopyprint1.df=DateFmat.getDateTimeInstance(DateFmat.FULLDateFmat.FULLLocale.CHINA)2.System.out.println(df.fmat(newDat

4、e()))如何如何獲取roid系統(tǒng)時(shí)間統(tǒng)時(shí)間是24小時(shí)制還是12小時(shí)制[java]viewplaincopyprint1.ContentResolvercv=this.getContentResolver()2.StringstrTimeFmat=roid.provider.Settings.System.getString(cv3.roid.provider.Settings.System.TIME_12_24)4.5.if(strT

5、imeFmat.equals(“24“))6.7.Log.i(“activity““24“)8.[java]viewplaincopyprint1.Calendarc=Calendar.getInstance()2.取得系統(tǒng)日期:year=c.get(Calendar.YEAR)3.month=c.grt(Calendar.MONTH)4.day=c.get(Calendar.DAY_OF_MONTH)5.取得系統(tǒng)時(shí)間：hour=c.g

6、et(Calendar.HOUR_OF_DAY)6.minute=c.get(Calendar.MINUTE)利用Calendar獲取[java]viewplaincopyprint1.Calendarc=Calendar.getInstance()2.取得系統(tǒng)日期:year=c.get(Calendar.YEAR)3.month=c.grt(Calendar.MONTH)4.day=c.get(Calendar.DAY_OF_MONT

7、H)5.取得系統(tǒng)時(shí)間：hour=c.get(Calendar.HOUR_OF_DAY)6.minute=c.get(Calendar.MINUTE)7.Calendarc=Calendar.getInstance()8.取得系統(tǒng)日期:year=c.get(Calendar.YEAR)9.month=c.grt(Calendar.MONTH)10.day=c.get(Calendar.DAY_OF_MONTH)11.取得系統(tǒng)時(shí)間：hour

8、=c.get(Calendar.HOUR_OF_DAY)12.minute=c.get(Calendar.MINUTE)利用Time獲取[java]viewplaincopyprint1.Timet=newTime()Timet=newTime(“GMT8“)加上TimeZone資料。2.t.setToNow()取得系統(tǒng)時(shí)間。3.intyear=t.year4.intmonth=t.month5.intdate=t.monthDay6.
