如何阻止在android系统中的DatePicker只有过去的日期？
现在用的样品code。在过去的日期和当前日期被阻塞，
我只需要过去的日期在这里得到不阻塞当前日期是我的code

 私人DatePickerDialog.OnDateSetListener mDateSetListener =
        新DatePickerDialog.OnDateSetListener（）{            公共无效onDateSet（查看的DatePicker，诠释yearSelected，
                                  INT monthOfYear，诠释请将dayOfMonth）{
               年= yearSelected;
               月= monthOfYear;
               天=请将dayOfMonth;
               INT n_mon = monthOfYear + 1;
               business_date_et.setText（日+ - + n_mon + - +年）;
            }
        };
        私人TimePickerDialog.OnTimeSetListener mTimeSetListener =
            新TimePickerDialog.OnTimeSetListener（）{                公共无效onTimeSet（TimePicker观点，诠释HOUROFDAY，诠释分钟）{
                    小时= HOUROFDAY;
                    分钟=分钟;                    business_time_et.setText（小时+：+分钟）;
                  }
            };
            保护对话框onCreateDialog（INT ID）{
                开关（ID）{
                案例DATE_DIALOG_ID：                    DatePickerDialog DA =新DatePickerDialog（这一点，mDateSetListener，
                            mYear，mMonth，MDAY）;
                    日历C = Calendar.getInstance（）;                    c.add（Calendar.DATE，1）;
                    日期newDate = c.getTime（）;
                    。da.getDatePicker（）setMinDate（newDate.getTime（））;
                    返回DA;                案例TIME_DIALOG_ID：
                    返回新TimePickerDialog（这一点，
                            mTimeSetListener，mHour，mMinute，FALSE）;                }
                返回null;
            }
 

解决方案

您也可以尝试这样的：

  da.getDatePicker（）setMinDate（newDate.getTime（） - （newDate.getTime（）％（24 * 60 * 60 * 1000）））。
 

有基本上减去由当前的日子的偏移的当前日期。

how to block only past date in DatePicker in android? Am using sample code in that past date and current date getting blocked , I need only past date get blocked not current date here is my code

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

            public void onDateSet(DatePicker view, int yearSelected,
                                  int monthOfYear, int dayOfMonth) {
               year = yearSelected;
               month = monthOfYear;
               day = dayOfMonth;
               int n_mon = monthOfYear+1;


               business_date_et.setText(day+"-"+n_mon+"-"+year);
            }
        };


        private TimePickerDialog.OnTimeSetListener mTimeSetListener =
            new TimePickerDialog.OnTimeSetListener() {

                public void onTimeSet(TimePicker view, int hourOfDay, int min) {
                    hour = hourOfDay;
                    minute = min;

                    business_time_et.setText(hour+":"+minute);
                  }
            };


            protected Dialog onCreateDialog(int id) {
                switch (id) {
                case DATE_DIALOG_ID:

                    DatePickerDialog da = new DatePickerDialog(this, mDateSetListener,
                            mYear, mMonth, mDay);
                    Calendar c = Calendar.getInstance();

                    c.add(Calendar.DATE, 1);
                    Date newDate = c.getTime();
                    da.getDatePicker().setMinDate(newDate.getTime());
                    return da;

                case TIME_DIALOG_ID:
                    return new TimePickerDialog(this,
                            mTimeSetListener, mHour, mMinute, false);

                }
                return null;
            }

解决方案

You can also try this:

da.getDatePicker().setMinDate(newDate.getTime()-(newDate.getTime()%(24*60*60*1000)));

It basically subtracts the current date by the current offset of the day.
