如何设置上个月的最短日期26



我尝试了什么：



int minDiffrence = 0;

if（day == 26）{

minDiffrence = difference;

} else {

minDiffrence =差异 - （26天）;

}



dpd.getDatePicker（）。setMinDate （System.currentTimeMillis（） - 24 * 60 * 60 * 1000 * minDiffrence）;

How to set minimum date to previous month 26

What I have tried:

int minDiffrence = 0;
if (day == 26) {
minDiffrence = difference;
} else {
minDiffrence = difference - (26 - day);
}

dpd.getDatePicker().setMinDate(System.currentTimeMillis() - 24 * 60 * 60 * 1000 * minDiffrence);

推荐答案

我不明白为什么你不会在下面使用这样的东西 - 你的方法看起来很复杂

I dont see why you wouldnt use something like this, below - your method looks 'complicated'

import java.util.Calendar;
// Get Calendar For Today
Calendar calNow = Calendar.getInstance();
// Subtract a month from the Calendar
calNow.add(Calendar.MONTH, -1);
// Set the Calendar Day of Month to 26
calNow.set(Calendar.DAY_OF_MONTH, 26);
//
// Set DatePicker MinDate Value
//
dpd.getDatePicker().setMinDate(calNow.getTimeInMillis());

在日期等方面使用正确的工具总是更好/更合适，它们为你处理月份等等





**免责声明 - 我不是java程序员，所以你需要仔细检查这项工作**

Its always better/more appropriate to use the correct tools where dates etc are concerned, they handle month wrap around etc for you


** Disclaimer - Im NOT a java programmer, so you need to check that work closely **
