android - 在当前日期时间之后设置 Datepicker minDate 会添加一个在 DatePickerDialog 顶部显示今天的文本

Question

如果日期选择器的最小日期早于当前日期时间，则 DatepickerDialog View 正常。 (第一张截图)

Calendar startDateCalendar = Calendar.getInstance();
DatePickerDialog datePickerDialog = new DatePickerDialog(this, null, startDateCalendar
        .get(Calendar.YEAR), startDateCalendar.get(Calendar.MONTH),
        startDateCalendar.get(Calendar.DAY_OF_MONTH));
DatePicker datePicker = datePickerDialog.getDatePicker();
Calendar max = Calendar.getInstance();
datePicker.setMinDate(max.getTimeInMillis() - 100);
datePickerDialog.show();

如果日期选择器的最小日期在当前日期时间之后，DatepickerDialog View 会在今天显示的 View 顶部添加一个 TextView 。 (第二张截图)

Calendar startDateCalendar = Calendar.getInstance();
DatePickerDialog datePickerDialog = new DatePickerDialog(this, null, startDateCalendar
        .get(Calendar.YEAR), startDateCalendar.get(Calendar.MONTH),
        startDateCalendar.get(Calendar.DAY_OF_MONTH));
DatePicker datePicker = datePickerDialog.getDatePicker();
Calendar max = Calendar.getInstance();
datePicker.setMinDate(max.getTimeInMillis() + 100);
datePickerDialog.show();

Answer 1

使用此代码:

DatePicker datePicker = datePickerDialog.getDatePicker();
datePicker.setMinDate(System.currentTimeMillis() + 100);
datePickerDialog.setTitle(null);
datePickerDialog.show();

快速解释:

• setMinDate 设置对话框标题，我们需要取消设置

• 使用 System.currentTimeMillis() 比调用更复杂的 Calendar.getInstance()

更高效
