Android獲取各式時間型別
阿新 • • 發佈：2018-12-11
在專案中需要獲取各式各樣的時間，而且也會有很多地方會呼叫到這些方法，所以我將它們歸集於一個檔案中，方便之後的使用。
現在我們需要了解一些相對基礎獲取時間的方法。
1.獲取當前日曆物件：
Calendar calendar = Calendar.getInstance();
calendar.getTimeInMillis();3.獲取標準格林尼治時間下日期時間對應的時間戳：
long unixTime = calendar.getTimeInMillis(); unixTime - TimeZone.getDefault().getRawOffset();
4.獲取當前日期物件：
Date date = new Date();5.獲取當前時區下日期時間對應的時間戳：
date.getTimeInMillis();6.設定日期時間格式：
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");7.獲取當前時區下日期時間對應的時間戳：
format.format(date);
現在來實現具體的方法。
1.獲取時間戳：
public static long getTime() { Calendar calendar = Calendar.getInstance();// 獲取當前日曆物件 long unixTime = calendar.getTimeInMillis();// 獲取當前時區下日期時間對應的時間戳 return unixTime; }
2.獲取標準的時間：
public static String getStandardTime() { SimpleDateFormat formatter = new SimpleDateFormat(BaseApplication.getInstance().getString(R.string.date_show_type_one)); Date curDate = new Date(System.currentTimeMillis());// 獲取當前時間 return formatter.format(curDate); }
3.獲取與現在時間的時間差（秒）：
public static int getDurationSecond(String time) {
int durationSecond = 0;
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date;
try {
date = df.parse(time);
MyLog.i("TimeUtils getDurationSecond Date=" + new Date().toString());
durationSecond = (int) ((new Date().getTime() - date.getTime()) / 1000);
} catch (Exception e) {
MyLog.e("TimeUtils getDurationSecond error=" + e);
}
return durationSecond;
}4.獲取時間差：
public static String getDuration(String one, String two) {
String duration = "";
SimpleDateFormat df = new SimpleDateFormat(<span style="font-family: SimHei;">"yyyy-MM-dd HH:mm:ss"</span>);
Date date1;
Date date2;
try {
date1 = df.parse(one);
date2 = df.parse(two);
int l = (int) ((date2.getTime() - date1.getTime()) / 1000 / 60);
if (l > 60) {
int hr = l / 60;
int min = l % 60;
duration = hr + "小時" + min + "分鐘";
} else {
duration = l + "分鐘";
}
} catch (Exception e) {
e.printStackTrace();
}
return duration;
}完整程式碼展示：
public class MyTimeUtils {
//獲取時間戳

Calendar calendar = Calendar.getInstance();// 獲取當前日曆物件
long unixTime = calendar.getTimeInMillis();// 獲取當前時區下日期時間對應的時間戳
return unixTime;
}

return Long.toString(new Date().getTime());
}
//獲取標準時間
public static String getStandardTime() {
SimpleDateFormat formatter = new SimpleDateFormat(BaseApplication.getInstance().getString(R.string.date_show_type_one));
Date curDate = new Date(System.currentTimeMillis());// 獲取當前時間
return formatter.format(curDate);
}
// 獲取與現在時間的時間差（秒）
public static int getDurationSecond(String time) {
int durationSecond = 0;
