【中文标题】在 Android 中设置 DatePickerDialog 的限制？【英文标题】：Set Limit on the DatePickerDialog in Android? 【发布时间】：2013-08-18 19:12:48 【问题描述】：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;
【问题讨论】：
【参考方案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：您可以从DatePickerDialog 获取底层DatePicker（只需调用getDatePicker()）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 Calendar 类应该是微不足道的：只需获取当前日期并添加或减去 x 年。
细心的读者会注意到，上述设置器直到 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 Gingerbread 设备（android 2.3 / API 级别 9+），您可以改用 backported version of DatePicker。
【讨论】：
那个项目在过去可以救我几天。很高兴知道！ 这就是这样做的方法：***.com/questions/13661788/… 我不清楚偏移量可能是负数，我可以在 1970 年之前获得数年。【参考方案2】：为 DatePickerDialog 设置最小和最大日期是不够的。用户可以点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);
【讨论】：
【参考方案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。但我可以给你一个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”是该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();
;

【参考方案4】： datePickerDialog = new CustomDatePickerDialog(this,
new OnDateSetListener()
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth)
// TODO Auto-generated method stub
try
Log.i("DAta SEt", "data set");
catch (Exception e)
, minYear, minMonth, minDay, maxYear, maxMonth, maxDay);
CustomDatePickerDialog：
public class CustomDatePickerDialog extends DatePickerDialog
private boolean mIgnoreEvent = false, mignorsunday = true;
public static int mYear, mMonth, mDate, maxYear, maxMonth, maxDay, minYear,
minMonth, minDay;
public static int dateflag = 0;
public static int dateflag2 = 0;
public CustomDatePickerDialog(Context context, OnDateSetListener callBack,
int year, int monthOfYear, int dayOfMonth, int maxYear,
int maxMonth, int maxDay)
super(context, callBack, year, monthOfYear, dayOfMonth);
// TODO Auto-generated constructor stub
dateflag = 0;
dateflag2 = 1;
mYear = year;
mMonth = monthOfYear;
mDate = dayOfMonth;
Log.i("Hello World ::", "Please Its Updating At Every time");
this.maxYear = maxYear;
this.maxMonth = maxMonth;
this.maxDay = maxDay;
this.minYear = year;
this.minMonth = monthOfYear;
this.minDay = dayOfMonth;
// setTitle("בחרו מתי נח לכם שנתקשר");
setTitle("We Call U...בחרו מתי נוח לכם ש");
@Override
public void onDateChanged(DatePicker view, int year, int month, int day)
// TODO Auto-generated method stub
super.onDateChanged(view, year, month, day);
dateflag = 1;
dateflag2 = 1;
if (!mIgnoreEvent)
mIgnoreEvent = true;
if (year > maxYear || month > maxMonth && year == maxYear
|| day > maxDay && year == maxYear && month == maxMonth)
mYear = maxYear;
mMonth = maxMonth;
mDate = maxDay;
view.updateDate(maxYear, maxMonth, maxDay);
else if (year < minYear || month < minMonth && year == minYear
|| day < minDay && year == minYear && month == minMonth)
mYear = minYear;
mMonth = minMonth;
mDate = minDay;
view.updateDate(minYear, minMonth, minDay);
else
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, year);
cal.set(Calendar.MONTH, month);
cal.set(Calendar.DATE, day);
if (cal.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)
if (mignorsunday)
cal.add(Calendar.DATE, 1);
mYear = cal.get(Calendar.YEAR);
mMonth = cal.get(Calendar.MONTH);
mDate = cal.get(Calendar.DATE);
mignorsunday = false;

【参考方案5】：这是工作代码，您必须根据您的代码进行一些更改。就像您可以添加儿童和婴儿的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;

我还在更新等待 @Gauravnow my ans is complete .. 添加条件以在 oncreate() 中根据 child 和 infant 更改 maxyear 和 minyear 在按钮上单击日历未打开。我必须在已发布的代码中进行哪些更改 @Gauravyou 必须在选择日期选择器之前根据孩子/婴儿设置 maxyear 和 minyear。如果选择了 childRadiobutton，则需要一个单选按钮来设置这些值设置范围为 2-12 否则为 0-2 .dynamically，一旦您进入日期选择器对话框，就不可能更改范围。这应该在打开对话框之前完成 你能帮我编辑我的代码吗，因为我试过你说的，但我做不到【参考方案6】：希望对您有所帮助。最好使用对话框片段，因为不推荐使用对话框的showDialog()。
另请注意，它仅适用于高于 11 的 API。因此，请将清单中的 min.sdk 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)

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");
