Android版的DatePicker没有星期天 [英] Android DatePicker without sundays

问题描述

我使用的是日期选择器选择一个特定的日期。在日期选择器不应该允许挑周日。截至现在我选择检测后，周日和显示信息，但它会更漂亮，如果日期选择器不允许周日。有没有办法做到这一点？

code检测星期日：

 私有静态类DatePickerFragment扩展DialogFragment实现DatePickerDialog.OnDateSetListener
 {    @覆盖
    公共对话框onCreateDialog（捆绑savedInstanceState）
    {
     [...]
    }    公共无效onDateSet（查看的DatePicker，年整型，诠释月，日整型）
    {
        现在日历= Calendar.getInstance（）;
        日历choosen = Calendar.getInstance（）;
        choosen.set（年，月，日）;
        如果（now.compareTo（choosen）℃，）
        {
            UserMessage.showMessage（已选定的日期是在未来，无效的日期，getActivity（））;
            返回;
        }否则如果（choosen.get（Calendar.DAY_OF_WEEK）== Calendar.SUNDAY）
        {
            UserMessage.showMessage（已选定的日期是星期天！，无效的日期，
                    getActivity（））;
            返回;
        }
        [...]
    }
}
 

解决方案

我解决了这个要求与创建含日期选择器自定义XML布局的自定义对话框。

我创建为大家下面的例子中，谁需要一个datepicker对话有特殊需求的一样，没有星期天，没有日期之前要提供一个具体日期来选择：

I am using an datepicker to choose a specific date. The datepicker should not allow to pick sundays. Till now i am detecting sundays after choice and show a message but it would be more nice if the datepicker doesn't allow sundays. Is there a way to do this?

Code to detect sundays:

 private static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener
 {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
     [...]
    }

    public void onDateSet(DatePicker view, int year, int month, int day)
    {
        Calendar now = Calendar.getInstance();
        Calendar choosen = Calendar.getInstance();
        choosen.set(year, month, day);
        if (now.compareTo(choosen) < 0)
        {
            UserMessage.showMessage("The choosen date is in future", "Invalid date", getActivity());
            return;
        } else if (choosen.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY)
        {
            UserMessage.showMessage("The choosen date is on sunday!", "Invalid date",
                    getActivity());
            return;
        }
        [...]
    }
}         

解决方案

I solved this requirements with creating a custom dialog containing a custom xml layout with datepicker.

I created the following example for everyone, who needs a datepicker dialog with special needs like no sundays, no dates earlier a specific date to be offered to choose:
