《Android》抓取手機上時間資訊

《Android》抓取手機上時間資訊


 


資料來源:http://bibby1101.pixnet.net/blog/post/44759449-%E3%80%8Aandroid%E3%80%8B%E6%8A%93%E5%8F%96%E6%89%8B%E6%A9%9F%E4%B8%8A%E6%99%82%E9%96%93%E8%B3%87%E8%A8%8A


 


SimpleDateFormat formatter = new SimpleDateFormat("yyyy年MM月dd日HH:mm:ss");


Date curDate = new Date(System.currentTimeMillis()) ; // 獲取當前時間


String str = formatter.format(curDate);


 


可以獲取當前的年月時分,也可以分開寫:


SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");


String date = sDateFormat.format(new java.util.Date());


 


如果想獲取當前的年月,則可以這樣寫(只獲取時間或秒種一樣):


SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM");


String date=sdf.format(new java.util.Date());


 


當然還有就是可以指定時區的時間(待):


df = DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.TAIWAN);


System.out.println(df.format(new Date()));



如何獲取Android系統時間是24小時制還是12小時制


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();


取得系統日期:year = c.get(Calendar.YEAR)


month = c.grt(Calendar.MONTH)


day = c.get(Calendar.DAY_OF_MONTH)


取得系統時間:hour = c.get(Calendar.HOUR_OF_DAY);


minute = c.get(Calendar.MINUTE)


 


利用Calendar獲取


Calendar c = Calendar.getInstance();


取得系統日期:year = c.get(Calendar.YEAR);


month = c.grt(Calendar.MONTH);


day = c.get(Calendar.DAY_OF_MONTH);


取得系統時間:hour = c.get(Calendar.HOUR_OF_DAY);


minute = c.get(Calendar.MINUTE);


 


Calendar c = Calendar.getInstance();


取得系統日期:year = c.get(Calendar.YEAR);


month = c.grt(Calendar.MONTH);


day = c.get(Calendar.DAY_OF_MONTH);


取得系統時間:hour = c.get(Calendar.HOUR_OF_DAY);


minute = c.get(Calendar.MINUTE);


 


利用Time獲取


Time t=new Time(); // or Time t=new Time("GMT+8"); 加上Time Zone資料。


t.setToNow(); // 取得系統時間。


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;

    Most people never even think about cholesterol until they are a little further along in life. Usually it becomes an issue after you graduate college, start a job and maybe even a family. Then the everyday stressors rear their ugly heads. This alone should tell you that cholesterol has at leas a little something to do with stress.
