如何在Android日期选择器中停用未来日期

Java代码：

mExpireDate.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                // To show current date in the datepicker
                final Calendar mcurrentDate = Calendar.getInstance();
                int mYear = mcurrentDate.get(Calendar.YEAR);
                int mMonth = mcurrentDate.get(Calendar.MONTH);
                int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                 DatePickerDialog mDatePicker = new DatePickerDialog(
                        EventRegisterActivity.this, new OnDateSetListener() {
                            public void onDateSet(DatePicker datepicker,
                                    int selectedyear, int selectedmonth,
                                    int selectedday) {

                                mcurrentDate.set(Calendar.YEAR, selectedyear);
                                mcurrentDate.set(Calendar.MONTH, selectedmonth);
                                mcurrentDate.set(Calendar.DAY_OF_MONTH,
                                        selectedday);
                                SimpleDateFormat sdf = new SimpleDateFormat(
                                        getResources().getString(
                                                R.string.date_card_formate),
                                        Locale.US);

                                mExpireDate.setText(sdf.format(mcurrentDate
                                        .getTime()));
                            }
                        }, mYear, mMonth, mDay);

                mDatePicker.setTitle(getResources().getString(
                        R.string.alert_date_select));
                mDatePicker.show();
            }
        });

怎么做？

Answer 1

使用DatePicker从DatePickerDialog获取getDatePicker()。使用setMaxDate()：

将最大日期设置为当前日期

mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());

需要API等级11。

Answer 2

您可以在DatePickerDialog上调用getDatePicker（）。setMaxDate（long），将今天设置为最大日期。您可以使用您发布的代码段中的相同名称更新该功能。

注意:: DatePickerDialog是我在Android文档中从我发布的链接中引用的对象。

@Override
protected Dialog onCreateDialog(int id) {
    Calendar c = Calendar.getInstance();
    int cyear = c.get(Calendar.YEAR);
    int cmonth = c.get(Calendar.MONTH);
    int cday = c.get(Calendar.DAY_OF_MONTH);
    switch (id) {
        case DATE_DIALOG_ID:
        //start changes...
        DatePickerDialog dialog = new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday);
        dialog.getDatePicker().setMaxDate(System.currentTimeMillis());
        return dialog;
        //end changes...
    }
    return null;
}

试试这个并提供反馈!!!

Answer 3

如果用户选择将来的日期，则将datepicker更新为当前日期（今天）

您可以使用以下代码检查所选的是未来日期

final Calendar cal = Calendar.getInstance();
datePickerDob.init(currentYear, currentMonth, currentDay,
            new OnDateChangedListener() {

                @Override
                public void onDateChanged(DatePicker view, int year,
                        int monthOfYear, int dayOfMonth) {
                    Calendar selectedCal = Calendar.getInstance();
                    selectedCal.set(year, monthOfYear, dayOfMonth);

                    long selectedMilli = selectedCal.getTimeInMillis();

                    Date datePickerDate = new Date(selectedMilli);
                    if (datePickerDate.after(new Date())) {

                        datePickerDob.updateDate(cal.get(Calendar.YEAR),
                                cal.get(Calendar.MONTH),
                                cal.get(Calendar.DAY_OF_MONTH));

                    } else {


                    }

                }
            });

您也可以使用compareTo（）方法

datePickerDate.compareTo(new Date());

将接收器与指定的日期进行比较，以确定相对排序。

参数日期与要比较的日期。

返回一个int＆lt;如果此Date小于指定的Date，则为0;如果它们相等则为0，并且int>如果此日期更大，则为0。

**new Way**

 ed_date.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Calendar mcurrentDate=Calendar.getInstance();
                year=mcurrentDate.get(Calendar.YEAR);
                month=mcurrentDate.get(Calendar.MONTH);
                day=mcurrentDate.get(Calendar.DAY_OF_MONTH);

                final DatePickerDialog   mDatePicker =new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener()
                {
                    @Override
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday)
                    {
                              ed_date.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
                            int month_k=selectedmonth+1;

                    }
                },year, month, day);
                mDatePicker.setTitle("Please select date");
                // TODO Hide Future Date Here
                mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());

                // TODO Hide Past Date Here
                //  mDatePicker.getDatePicker().setMinDate(System.currentTimeMillis());
                mDatePicker.show();
            }
        });

Answer 5

如果您使用材质设计Datepicker：

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    DatePickerDialog datePickerDialog = DatePickerDialog.newInstance(this,
            calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
    datePickerDialog.show(getFragmentManager(), "datepicker");
    datePickerDialog.setMaxDate(calendar);

Answer 6

 // Custom Your Future Dates  

 // Example for today and next 3 days :- 3(NUMBER OF NEXT DAYS)*24*60*60*1000l

 // As 24 represents hrs in day

 // As 60 mins 60 secs and convert it to millisec

 //Inside Class which implements DatePickerDialog.OnDateSetListener
 private Calendar mCurrentDate;

 //Inside OnCreate Method
 mDateEditText.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

   mCurrentDate = Calendar.getInstance();
   int year = mCurrentDate.get(Calendar.YEAR);
   int month = mCurrentDate.get(Calendar.MONTH);
   int day = mCurrentDate.get(Calendar.DAY_OF_MONTH);

   DatePickerDialog mDatePickerDialog = new DatePickerDialog(this, this, year, month, day);
   mDatePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis() + 3 * 24 * 60 * 60 * 1000 l);
  }
 });


 @Override
 public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
  mDateEditText.setText(dayOfMonth + "/" + month + "/" + year);

 }

Answer 7

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    DatePickerDialog dialog = new DatePickerDialog(getActivity(), ondateSet, year, month, day);
    Calendar c = Calendar.getInstance();
    c.add(Calendar.DATE, 1);
    Date newDate = c.getTime();
    dialog.getDatePicker().setMaxDate(newDate.getTime() - (newDate.getTime() % (24 * 60 * 60 * 1000)));
    return  dialog;
}

Answer 8

以下代码可帮助您禁用将来的日期：

全局声明日历变量：

private Calendar myCalendar = Calendar.getInstance();

在onCreate方法中放置以下代码：

DatePickerDialog.OnDateSetListener dateListener = 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);
        updateLabel();
    }

};

在按钮上单击，输入以下代码：

DatePickerDialog datePickerDialog=new DatePickerDialog(getActivity(), dateListener, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH));

               //following line to restrict future date selection     
            datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
            datePickerDialog.show();

Answer 9

设置直到明天的最大日期代码中的最后一位数字代表您要设置的天数。

  pickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis() + (1000 * 60 * 60 * 24 * 1));
