android - 在 Android 中设置 DatePickerDialog 的限制？

Question

如何限制 DatePickerDialog 选择过去 2-12 年或当前日期 0-2 年的日期？

我在活动中有 DatePickerDialog，用于获取儿童和婴儿的出生日期。儿童年龄为（2-12 岁），婴儿年龄为（0-2 岁）。如果我通过 1，那么年龄限制应该是（2-12 岁），如果我通过 2，年龄限制应该是（0-2 岁）。

我可以做些什么来在我的日历中获得这个功能？

我的日历代码是：

date = new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                    int dayOfMonth) {
                // TODO Auto-generated method stub
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                String myFormat = "dd/MM/yy"; //In which you need put here
                SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
                dateofBirth.setText(sdf.format(myCalendar.getTime()));
            }
        };

dateofBirth.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                showDialog(DATE_DIALOG_ID);

            }
        });

public Dialog onCreateDialog(int id) {
    final Calendar now = Calendar.getInstance();

    switch (id) {
    case DATE_DIALOG_ID:
        // set date picker as current date
        DatePickerDialog _date =   new DatePickerDialog(this, date,myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)){
            @Override

            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth){   

                if (year > now.get(Calendar.YEAR))

                    view.updateDate(myCalendar
                            .get(Calendar.YEAR), myCalendar
                            .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));

                if (monthOfYear > now.get(Calendar.MONTH) && year == now.get(Calendar.YEAR))
                    view.updateDate(myCalendar
                            .get(Calendar.YEAR), myCalendar
                            .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));

                if (dayOfMonth > now.get(Calendar.DAY_OF_MONTH) && year == now.get(Calendar.YEAR) && 
                        monthOfYear == now.get(Calendar.MONTH))
                    view.updateDate(myCalendar
                            .get(Calendar.YEAR), myCalendar
                            .get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));
            }

        };

        return _date;
    }
    return null;
}

Answer 1

所有其他答案似乎都相当复杂，所以我只想说明显而易见的：您可以DatePicker从 a DatePickerDialog（通过简单地调用getDatePicker()）获取底层并使用以下方法设置其界限：

• setMinDate(long minDate)
• setMaxDate(long maxDate)

其中参数是自默认时区 1970 年 1 月 1 日 00:00:00 以来的通常毫秒数。当然，您仍然需要计算这些值，但这对于课程来说应该是微不足道的Calendar：只需获取当前日期并添加或减去x年份。

细心的读者会注意到前面提到的 setter 直到 API 级别 11 才可用。如果您只针对该（或更新的）平台，那么您就可以开始了。如果您还想支持 ie Gingerbread 设备（Android 2.3 / API 级别 9+），您可以使用向后移植的版本来DatePicker代替。

Answer 2

为 DatePickerDialog 设置最小和最大日期是不够的。用户可以单击年份并在年份之间滚动。

您还应该像这样在 DatePicker 上设置年份范围：

datePicker.setYearRange(calendar.get(Calendar.YEAR), calendar.get(Calendar.YEAR) + 1);

Answer 3

我无法为您提供工作代码，因为我正在旅行并且无法访问我的 PC。但我可以给你一种方法来实现你的目标（或者我认为）。

我不确定这是否会完美运行，但任何方式都值得一试。

请尝试此代码并通知我。

“DatepickerType”是类的一个整数公共成员变量。

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {

    // when dialog box is closed, below method will be called.
    public void onDateSet(DatePicker view, int selectedYear,
            int selectedMonth, int selectedDay) {
        int y = Calendar.getInstance().get(Calendar.YEAR);
        switch(DatepickerType){
        case 1:
            if(selectedYear>(y-2)){
                //Add message if you want
                selectedYear = y-2;
            }
                else if(selectedYear<(y-12)) {
                //Add msg if u want
                    selectedYear = y-12;
            }

        case 2:
            if(selectedYear>(y)){
                //Add message if you want
                selectedYear = y;
            }
                else if(selectedYear<(y-2)) {
                //Add msg if u want
                    selectedYear = y-2;
            }
        }

        String year1 = String.valueOf(selectedYear);
        String month1 = String.valueOf(selectedMonth+1);
        String day1 = String.valueOf(selectedDay);
        //do what you need
        setLastStatus();

    }
};

    datePickerDialog = new CustomDatePickerDialog(this,
                new OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year,

                }, minYear, minMonth, minDay, maxYear, maxMonth, maxDay);

自定义日期选择器对话框：

Answer 5

这是工作代码，您必须根据您的代码进行一些更改。就像您可以为儿童和婴儿添加最小和最大年龄一样。

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {

    public void onDateSet(DatePicker view, int year, int monthOfYear,
                          int dayOfMonth) {
    /*
     * mYear = year;
     * mMonth = monthOfYear;
     * mDay = dayOfMonth;
     */
        if (year > maxYear || monthOfYear > maxMonth && year == maxYear ||
                dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth) {
            view.updateDate(maxYear, maxMonth, maxDay);
            //you can add toast message here for max year selection
        } else if (year < minYear || monthOfYear < minMonth && year == minYear ||
                dayOfMonth < minDay && year == minYear && monthOfYear == minMonth) {
            view.updateDate(minYear, minMonth, minDay);
            //you can add toast message here for min year selection
        } else {
            view.updateDate(year, monthOfYear, dayOfMonth);
        }
    }

};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mPickDate = (Button) findViewById(R.id.pickDate);
    mPickDate.setOnClickListener(this);

    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    maxYear = mYear - 2;//make a proper condition to change it the based on the   child/infant
    maxMonth = mMonth;
    maxDay = mDay;

    minYear = mYear - 12;//make a proper condition to change it the based on the child/infant
    minMonth = mMonth;
    minDay = mDay;

}

@Override
public void onClick(View v) {
    showDialog(DATE_DIALOG_ID);
}

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this, mDateSetListener, mYear - minYear,
                    mMonth, mDay);
    }
    return null;
}

Answer 6

愿这对你有所帮助。最好使用对话框片段，因为showDialog()Dialog 已弃用。另请记住，它仅适用于高于 11 的 API。因此，min.sdk将清单更改为 11。

Calendar calendar=Calendar.getInstance();
    int mDay = calendar.get(Calendar.DAY_OF_MONTH), mMonth = calendar.get(Calendar.MONTH), mYear = calendar.get(Calendar.YEAR);


    int minDay = calendar.get(Calendar.DAY_OF_MONTH), minMonth = calendar.get(Calendar.MONTH), minYear = calendar.get(Calendar.YEAR)-12;

int maxDay = calendar.get(Calendar.DAY_OF_MONTH), maxMonth = calendar.get(Calendar.MONTH), maxYear = calendar.get(Calendar.YEAR)-12;


public void onDate(View view) {
        System.out.println("hello");
        DialogFragment fragment = new SelectDateFragment();
        fragment.show(getFragmentManager(), "Date Picker");
    }

    class SelectDateFragment extends DialogFragment implements
            DatePickerDialog.OnDateSetListener {

        public Dialog onCreateDialog(Bundle savedInstanceState) {


            System.out.println("entrering on create dialog");;

            return new DatePickerDialog(getActivity(), this, mYear, mMonth,
                    mDay) {

                public void onDateChanged(DatePicker view, int year,
                        int monthOfYear, int dayOfMonth) {
                    System.out.println("----------onDateChanged()-----------"
                            + year + "--" + year);
                    System.out.println("----------onDateChanged()-----------"
                            + monthOfYear + "--" + monthOfYear);
                    System.out.println("----------onDateChanged()-----------"
                            + dayOfMonth + "--" + dayOfMonth);

                    if ((minYear < year)
                            || ((minMonth < monthOfYear) && (minYear == year))
                            || ((minDay < dayOfMonth) && (minYear == year) && (minMonth == monthOfYear))) {
                        view.updateDate(minYear, minMonth - 1, minDay);

                    }

if ((maxYear > year)
                            || ((maxMonth > monthOfYear) && (maxYear == year))
                            || ((maxDay > dayOfMonth) && (maxYear == year) && (maxMonth == monthOfYear))) {
                        view.updateDate(maxYear, maxMonth - 1, maxDay);

                    }

                }
            };

        }

        @Override
        public void onDateSet(android.widget.DatePicker view, int year,
                int monthOfYear, int dayOfMonth) {
            System.out.println("year=" + year + "day=" + dayOfMonth + "month="
                    + monthOfYear);
            mYear=year;
            mMonth=monthOfYear;
            mDay=dayOfMonth;

            onPopulateSet(year, monthOfYear + 1, dayOfMonth);

        }


        private void onPopulateSet(int year, int i, int dayOfMonth) {
            EditText et_setDate;
            et_setDate = (EditText) findViewById(R.id.register_et_dob);
            et_setDate.setText(dayOfMonth + "/" + i + "/" + year);
            System.out.println("enetring on populate Set");

        }
