Question

我正在使用自定义日期选择器，我就是这样使用的。

public class DatePickersDialog extends DatePickerDialog implements OnDateChangedListener {

    private DatePickerDialog mDatePicker;

     public DatePickersDialog(Context context, OnDateSetListener callBack,
            int year, int monthOfYear, int dayOfMonth) {
        super(context,callBack, year, monthOfYear, dayOfMonth);
       mDatePicker = new DatePickerDialog(context,callBack, year, monthOfYear, dayOfMonth);
       mDatePicker.getDatePicker().init(year, monthOfYear, dayOfMonth, this);
        updateTitle(year, monthOfYear);

    }
    public void onDateChanged(DatePicker view, int year,
        int month, int day) {
    updateTitle(year, month);
    }
    private void updateTitle(int year, int month) {
        Calendar mCalendar = Calendar.getInstance();
        mCalendar.set(Calendar.YEAR, year);
        mCalendar.set(Calendar.MONTH, month);
        mDatePicker.setTitle(getFormat().format(mCalendar.getTime()));

    }  
    public DatePickerDialog getPicker(){
        return this.mDatePicker;
    }

    public SimpleDateFormat getFormat(){
    return new SimpleDateFormat("MMM, yyyy");
    };   

   }
Utils.class 


public static DatePickerDialog customDatePickers(Activity activity, DatePickerDialog.OnDateSetListener datePickerListener) {

    Calendar c = Calendar.getInstance();
    int cardYear = c.get(Calendar.YEAR);
    int cardMonth = c.get(Calendar.MONTH);
    int cardDay = c.get(Calendar.DAY_OF_MONTH);
    DatePickersDialog datePickersDialog = new DatePickersDialog(activity,datePickerListener,cardYear,cardMonth,cardDay);
    Date minDate = new Date();
    c.set(cardYear, cardMonth, cardDay - 1, 0, 0);
    minDate.setTime(c.getTimeInMillis());
    DatePickerDialog datePickerDialog = datePickersDialog.getPicker();

    try {
        Field[] datePickerDialogFields = datePickerDialog.getClass().getDeclaredFields();
        for (Field datePickerDialogField : datePickerDialogFields) {
            if (datePickerDialogField.getName().equals("mDatePicker")) {
                datePickerDialogField.setAccessible(true);
                DatePicker datePicker = (DatePicker) datePickerDialogField.get(datePickerDialog);
                Field datePickerFields[] = datePickerDialogField.getType()
                        .getDeclaredFields();
                for (Field datePickerField : datePickerFields) {
                    if ("mDayPicker".equals(datePickerField.getName()) || "mDaySpinner".equals(datePickerField.getName())) {
                        datePickerField.setAccessible(true);
                        Object dayPicker = new Object();
                        dayPicker = datePickerField.get(datePicker);
                        ((View) dayPicker).setVisibility(View.GONE);
                    }
                }
            }
        }
        datePickerDialog.show();
    } catch (Exception ex) {
    }
    return datePickerDialog;
}

 scanExpireDate = (CheckoutEditText) findViewById(R.id.scan_expire_date);
scanExpireDate.setTextView();



public void onDatePickerClick(View view){
            Utils.customDatePicker(this, datePickerListener);
    }

但它显示如下图。显示上一年和一个月。如何限制？ enter image description here

如何解决这个问题？

Answer 1

使用以下方式设置其边界：

setMinDate(long minDate)
setMaxDate(long maxDate)

其中参数是自默认时区1970年1月1日1970:00 00:00:00以来的通常毫秒数。当然，你仍然需要计算这些值，但这对于Calendar类来说应该是微不足道的：只需要获取当前日期并添加或减去x年。

编辑：您可以从DatePickerDialog获取基础DatePicker（通过简单地调用getDatePicker（））或在您的代码中我认为它是您调用DatePicker datePicker的地方，只需添加如下行：

datePicker.setMinDate(<long variable>);

我通过在自定义日期选择器中使用它来修复此问题。希望它对某人有帮助

DatePickerDialog datePickerDialog = datePickersDialog.getPicker（）; 。datePickerDialog.getDatePicker（）setMinDate（minDate.getTime（））;

如何在日期选择器中显示当前月份和年份以限制显示上一年和月份的android？
