Question

我的Android应用程序需要一个日历，其日期为18年前的maxDate。到目前为止，我尝试了这段代码，但它只是说Integer number is too large

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    view.setMaxDate(System.currentTimeMillis() - 31556926000);
    year_x = year;
    month_x = monthOfYear + 1;
    day_x = dayOfMonth;
    etBirthDate.setText(month_x + "/" +  day_x + "/" + year_x);
}
};

Answer 1

要更好地了解您的问题，请参阅：http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html部分整数文字。它声明：

如果整数文字以字母L或l结尾，则其长度为long;否则它是int类型。建议您使用大写字母L，因为小写字母l很难与数字1区分开来。

最简单的解决方案：

view.setMaxDate(System.currentTimeMillis() - 31556926000L);

但我会选择：

Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.YEAR, -18);
view.setMaxDate(calendar.getTimeInMillis());

 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(
            getContext(), new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker datepicker,
                              int selectedyear, int selectedmonth,
                              int selectedday) {
            selectedyear=selectedyear;
            mcurrentDate.set(Calendar.YEAR, selectedyear);
            mcurrentDate.set(Calendar.MONTH, selectedmonth);
            mcurrentDate.set(Calendar.DAY_OF_MONTH, selectedday);
            SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy", Locale.US);
            edtxtDOB.setText(sdf.format(mcurrentDate.getTime()));


        }
    }, mYear-18, mMonth, mDay);
    mcurrentDate.set(mYear-18,mMonth,mDay);
    long value=mcurrentDate.getTimeInMillis();
    mDatePicker.getDatePicker().setMaxDate(value);
    mDatePicker.show();

Android工作室日历设置maxDate 18年前
