Android DatePicker 对话框，日期应该来自明天

Question

 Calendar calender = Calendar.getInstance();
    final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(LabCheckOutActivity.this,
    myDateListener, calender.get(Calendar.YEAR), calender.get(Calendar.MONTH),
    calender.get(Calendar.DAY_OF_MONTH)+1);
    pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()-1000);
    pickerDialog.show();

通过使用此代码，对话框中的日期指向明天，但用户也可以选择今天的日期。我希望用户可以选择明天而不是今天的日期。

公共类 CustomDatePickerDialog 扩展 DatePickerDialog {

int maxYear;
int maxMonth;
int maxDay;

public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
    super(context, callBack, year, monthOfYear, dayOfMonth);
}

public void setMaxDate(long maxDate) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        getDatePicker().setMaxDate(System.currentTimeMillis());
    } else {
        final Calendar c = Calendar.getInstance();
        c.setTimeInMillis(maxDate);
        maxYear = c.get(Calendar.YEAR);
        maxMonth = c.get(Calendar.MONTH);
        maxDay = c.get(Calendar.DAY_OF_MONTH);
    }
}

@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        super.onDateChanged(view, year, monthOfYear, dayOfMonth);
    } else {
        if (year > maxYear)
            view.updateDate(maxYear, maxMonth, maxDay);

        if (monthOfYear > maxMonth && year == maxYear)
            view.updateDate(maxYear, maxMonth, maxDay);

        if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
            view.updateDate(maxYear, maxMonth, maxDay);
    }
}

}

使用

pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()+24*60*60*1000);//where 24*60*60*1000 represents the total timestamp for one day

代替

  pickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()-1000);
