在Android中设置DatePickerDialog的限制？,android,android-datepicker,datepickerdialog,Android,Android Datepicker,Datepickerdialog,如何限制DatePickerDialog以选择过去2-12年或当前日期0-2年的日期 我在活动中设置了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，则年龄限制应为（2-12岁），如果我通过2，则年龄限制应为（0-2岁） 如何在日历中使用此功能 我的日历代码是： date = new DatePickerDialog.OnDateSetListener() { @Override

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

我在活动中设置了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，则年龄限制应为（2-12岁），如果我通过2，则年龄限制应为（0-2岁）

如何在日历中使用此功能

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;
}

我无法向您提供工作代码，因为我正在旅行，无法访问我的电脑。但我可以为您提供实现目标的方法（或者我认为是这样）

我不确定这是否能完美地工作，但无论如何都值得一试

请尝试此代码并通知我

“DatepickerType”是该类的整数公共成员变量

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;
