Question

我之前在Google上找到了一个教程，用于同一个对话框上的日期和时间选择器。我试图在日历上设置minDate和maxDate，但没有任何帮助。我想在用户打开对话框时选择日期默认日期比当前日期提前4天。为此，我试图把

datePicker.setMinDate(System.currentTimeMillis() + 4);

但是当我打开对话框时，没有任何改变。代码有点长，我将尝试仅发布我认为需要的内容。这是CustomDateTimePicker.java

public void showDialog() {
if (!dialog.isShowing()) {
    if (calendar_date == null)
        calendar_date = Calendar.getInstance();

    selectedHour = calendar_date.get(Calendar.HOUR_OF_DAY);
    selectedMinute = calendar_date.get(Calendar.MINUTE);

    timePicker.setIs24HourView(is24HourView);
    timePicker.setCurrentHour(selectedHour);
    timePicker.setCurrentMinute(selectedMinute);

    //
    datePicker.updateDate(calendar_date.get(Calendar.YEAR),
            calendar_date.get(Calendar.MONTH),
            calendar_date.get(Calendar.DATE));


    dialog.show();

    btn_setDate.performClick();
}
}

public void setAutoDismiss(boolean isAutoDismiss) {
    this.isAutoDismiss = isAutoDismiss;
}

public void dismissDialog() {
   if (!dialog.isShowing())
      dialog.dismiss();
 }

public void setDate(Calendar calendar) {
   if (calendar != null)
    calendar_date = calendar;
}

 public void setDate(Date date) {
   if (date != null) {
    calendar_date = Calendar.getInstance();
    calendar_date.setTime(date);
  }
 }

 public void setDate(int year, int month, int day) {
   if (month < 12 && month >= 0 && day < 32 && day >= 0 && year > 100
        && year < 3000) {
    calendar_date = Calendar.getInstance();
    calendar_date.set(year, month, day);

  }

 }

 public void setTimeIn24HourFormat(int hourIn24Format, int minute) {
 if (hourIn24Format < 24 && hourIn24Format >= 0 && minute >= 0
        && minute < 60) {
    if (calendar_date == null)
        calendar_date = Calendar.getInstance();

    calendar_date.set(calendar_date.get(Calendar.YEAR),
            calendar_date.get(Calendar.MONTH),
            calendar_date.get(Calendar.DAY_OF_MONTH), hourIn24Format,
            minute);

    is24HourView = true;
  }
}

这是MainActivity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    custom = new CustomDateTimePicker(this,
            new CustomDateTimePicker.ICustomDateTimeListener() {

                @Override
                public void onSet(Dialog dialog, Calendar calendarSelected,
                        Date dateSelected, int year, String monthFullName,
                        String monthShortName, int monthNumber, int date,
                        String weekDayFullName, String weekDayShortName,
                        int hour24, int hour12, int min, int sec,
                        String AM_PM) {
                    ((EditText) findViewById(R.id.datePicker)).setText(calendarSelected.get(Calendar.DAY_OF_MONTH)
                                    + "-" + (monthNumber+1) + "-" + year
                                    + " " + hour24 + ":" + min);              
                }

                @Override
                public void onCancel() {

                }
            });

    /**
     * Pass Directly current time format it will return AM and PM if you set
     * false
     */
    custom.set24HourFormat(false);
    /**
     * Pass Directly current data and time to show when it pop up
     */
    custom.setDate(Calendar.getInstance());

    findViewById(R.id.btnCalendar).setOnClickListener(
            new OnClickListener() {

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

});

我相信这是我需要解决的部分，但无法确切地了解它。如有需要，此处的完整代码为CustomDateTimePicker.java - ＆gt; http://pastebin.com/UnifiAWu

Answer 1

datePicker.setMinDate(System.currentTimeMillis() + 4);

您正在向当前时间添加4毫秒并将其作为minDate传递。要解决此问题，您必须将4天转换为毫秒，并将其添加到当前时间。

同一对话框上的DateTime选择器不接受minDate和maxDate
