如何在 Android Studio 中計算工作日？
[英]How to count working days in Android Studio?
問題描述
我想要做的是從兩個定義的日期（月初和月底）計算工作日。
我正在使用我發現的一個函數，它接收三個參數， start date 、 end date和a list of dates of non-working days （假期和其他a list of dates of non-working days 。
下面的代碼給了我 23 個工作日，但實際結果必須是22 working days 。
例如
Start date is - 2020-03-01 and
End Date is - 2020-03-31
With 7 non-working days
（日期從 DatePickerDialog 中選擇並存儲在變量dateIni和dateFin ）

2 個解決方案
解決方案1
1 2020-03-11 22:17:45
這不是初始化Date對象的方式：
new Date(2020-3-24)
2020-3-24是減法，因此您將其初始化為 2020-3-24=1993 毫秒自 GMT 1970 年 1 月 1 日開始。
new Date(2020, 3, 24)
解決方案2
0 2020-03-12 17:02:00
我已經解決了。 我修改了函數，現在接收到的參數是Calendar類型的三個。 前面的代碼計算工作日，但比較日期部分與數組列表（包含假期）不起作用。 我分享解決方案，以防有人使用它。
