android - 如何将最小 DatePicker 日期设置为当前日期

Question

我想将用户可以在 DatePicker 中选择的最小日期设置为当前日期。我试过这个：

DatePicker datePicker = (DatePicker) findViewById(R.id.event_date);
datePicker.setMinDate(System.currentTimeMillis());

这给了我以下例外：

12-01 12:23:31.226: E/AndroidRuntime(10311): Caused by: java.lang.IllegalArgumentException: fromDate: Sat Dec 01 12:23:31 EST 2012 does not precede toDate: Sat Dec 01 12:23:31 EST 2012

我该怎么做呢？

该错误表示您无法将最短日期设置为现在。尝试减去一秒：

datePicker.setMinDate(System.currentTimeMillis() - 1000);

从源代码来看，最小日期必须早于，不等于，当前日期：

if (date.before(mMinDate)) {
    throw new IllegalArgumentException("fromDate: " + mMinDate.getTime()
            + " does not precede toDate: " + date.getTime());
}

所以你只需要从 now ( System.currentTimeMillis()) pass中减去足够的时间date.before(mMinDate)。

如果您不想使用自定义对话框。使用这个单行代码：

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());

检查 Android DatePickerDialog设置最小和最大日期代码。

这里是例子。

final Calendar c = Calendar.getInstance();  
    int year = c.get(Calendar.YEAR);  
    int month = c.get(Calendar.MONTH);  
    int day = c.get(Calendar.DAY_OF_MONTH);  
DatePickerDialog dpd = new DatePickerDialog(getActivity(),AlertDialog.THEME_TRADITIONAL,this,year, month, day);  

    //Get the DatePicker instance from DatePickerDialog  
    DatePicker dp = dpd.getDatePicker();  
    //Set the DatePicker minimum date selection to current date  
    dp.setMinDate(c.getTimeInMillis());//get the current day  
    //dp.setMinDate(System.currentTimeMillis() - 1000);// Alternate way to get the current day  

    //Add 6 days with current date  
    c.add(Calendar.DAY_OF_MONTH,6);  

    //Set the maximum date to select from DatePickerDialog  
    dp.setMaxDate(c.getTimeInMillis());  
    //Now DatePickerDialog have 7 days range to get selection any one from those dates

这对我来说非常有效。简单而美好。

DatePickerDialog dialog = new DatePickerDialog(this, this,
              Calendar.YEAR,Calendar.MONTH,
                Calendar.DAY_OF_MONTH);

        dialog.getDatePicker().setMinDate(Calendar.getInstance().getTimeInMillis());
        dialog.show();

将此行添加到您的 DatePicker Fragment 会将最小日期设置为当前日期并禁用前几个月。

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());

这可以帮助你。

Calendar cal=Calendar.getInstance();

int year=cal.get(Calendar.YEAR);
int month=cal.get(Calendar.MONTH);
int day=cal.get(Calendar.DAY_OF_MONTH);
int hour=cal.get(Calendar.HOUR_OF_DAY);
int min=cal.get(Calendar.MINUTE);

datePicker.updateDate(year, month, day);

timePicker.setCurrentHour(hour);
timePicker.setCurrentMinute(min);

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());

或者

DatePickerDialog dialog = new DatePickerDialog(this, this,
          Calendar.YEAR,Calendar.MONTH,
            Calendar.DAY_OF_MONTH);

    dialog.getDatePicker().setMinDate(Calendar.getInstance().getTimeInMillis());
    dialog.show();

datePicker.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);

最短的日期不能是瞬间

对于自定义日期

Calendar c = Calendar.getInstance();
c.set(2017, 0, 1);//Year,Month -1,Day
your_date_picker.setMaxDate(c.getTimeInMillis());
