在Android日期选择器中禁用特定日期 [英] Disable specific dates of day in Android date picker

问题描述

我正在使用datePicker，我可以通过以下代码禁用今天和30天后的最后几天：

I'm using the datePicker and I can disable last days of today and later days after 30 days by the following code:

DatePickerDialog datePicker = new DatePickerDialog();

             Calendar calender = Calendar.getInstance();
             long today = calender.getTimeInMillis();
             final long oneDay = 24 * 60 * 60 * 1000L;

             Date previousDays = new Date(today - 1000);
             datePicker.setMinDate(DateToCalendar(previousDays));

             Date nextMonth = new Date(today + 30 * oneDay);
             datePicker.setMaxDate(DateToCalendar(nextMonth));

如果我要禁用每个月的星期五，我该怎么做？

If I want to disable Friday of every month, how can I do this?

推荐答案

这是不可能的android datepicker，你需要为自己创建一个自定义选择器。请参阅 MaterialDateTimePicker

That is not possible with the android datepicker and you need to create a custom picker for yourself. See MaterialDateTimePicker

要禁用星期日您有通过这样的数组

To disable Sundays you have to pass the array like this

List<Calendar> dayslist= new LinkedList<Calendar>();
Calendar[] daysArray;
Calendar cAux = Calendar.getInstance();
while ( cAux.getTimeInMillis() <= gc.getTimeInMillis()) {
    if (cAux.get(Calendar.DAY_OF_WEEK) != 1) {
        Calendar c = Calendar.getInstance();
        c.setTimeInMillis(cAux.getTimeInMillis());
        dayslist.add(c);
    }
    cAux.setTimeInMillis(cAux.getTimeInMillis() + (24*60*60*1000));
}
daysArray = new Calendar[dayslist.size()];
for (int i = 0; i<daysArray.length;i++)
{
    daysArray[i]=dayslist.get(i);
}
datePickerDialog.setSelectableDays(daysArray);
