如何隐藏/删除 datepickerdialog 中的日期字段。实际上，我的要求是使用本机日期选择器对话框，但它显示为日、月和年。但根据我的要求，我只需要一个月和一年。所以我想从视图中隐藏或删除日期字段。

任何帮助都会非常有用。

我不建议使用反射来做这种事情。

有一种更简单、更漂亮的方法可以做到这一点：

((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);

请注意，该.getDatePicker()方法DatePickerDialog适用于API LEVEL >= 11.

Private DatePickerDialog createDialogWithoutDateField(){

    DatePickerDialog dpd = new DatePickerDialog(_activity, ExpiryDateSetListener,cyear,cmonth, cday);
    try{
    Field[] datePickerDialogFields = dpd.getClass().getDeclaredFields();
    for (Field datePickerDialogField : datePickerDialogFields) { 
        if (datePickerDialogField.getName().equals("mDatePicker")) {
            datePickerDialogField.setAccessible(true);
            DatePicker datePicker = (DatePicker) datePickerDialogField.get(dpd);
            Field datePickerFields[] = datePickerDialogField.getType().getDeclaredFields();
            for (Field datePickerField : datePickerFields) {
               if ("mDayPicker".equals(datePickerField.getName())) {
                  datePickerField.setAccessible(true);
                  Object dayPicker = new Object();
                  dayPicker = datePickerField.get(datePicker);
                  ((View) dayPicker).setVisibility(View.GONE);
               }
            }
         }

      }
    }catch(Exception ex){
    }
  return dpd;

}

使用上面的代码隐藏 DatePickerDialog 中的日期字段。

dialog_date_picker.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/rounded_corners"
android:orientation="vertical"

<DatePicker

    android:textColor="@color/colorWhite" /></LinearLayout>

单击时调用的 DialogMethod：

private void ExpiryDialog() {
    System.out.println("Inside Dialog Box");
    final Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog_date_picker);
    dialog.show();
    final DatePicker datePicker = (DatePicker) dialog.findViewById(R.id.date_picker);
    date_time_set = (Button) dialog.findViewById(R.id.date_time_set);
    datePicker.init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), null);

    LinearLayout ll = (LinearLayout) datePicker.getChildAt(0);
    LinearLayout ll2 = (LinearLayout) ll.getChildAt(0);
    ll2.getChildAt(1).setVisibility(View.INVISIBLE);

    date_time_set.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view){
            dialog.dismiss();
            Integer month = datePicker.getMonth()+1;
            Integer year = datePicker.getYear();
            expMonth = (month.toString().length()   == 1 ? "0"+month.toString():month.toString());
            expYear = year.toString();
            etExpiryDate.setText(expMonth + "/" + expYear);
        }
    });
}

此代码有效并将日期隐藏在 DatePicker 中，因此我可以显示卡片的到期日期。享受！！

我有点太晚了，但是在上面发布@ULHAS PATIL 提供的编辑答案，以防有人需要同样的东西！

应该有索引 0 来隐藏填充的日期，在 ll2.getChildAt(0).setVisibility(View.GONE); 并且可见性设置为 View.GONE，因此日期字段的空间未被占用。

private void createDialogWithoutDateField() {
    Calendar mCalendar;
    mCalendar = Calendar.getInstance();
    System.out.println("Inside Dialog Box");
    final Dialog dialog = new Dialog(requireContext());
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.date_picker_layout);
    dialog.show();

    final DatePicker datePicker = (DatePicker) dialog.findViewById(R.id.date_picker);
    AppCompatButton okBtn = (AppCompatButton) dialog.findViewById(R.id.ok);
    AppCompatButton cancelBtn = (AppCompatButton) dialog.findViewById(R.id.cancel);
    datePicker.init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), null);

    LinearLayout ll = (LinearLayout) datePicker.getChildAt(0);
    LinearLayout ll2 = (LinearLayout) ll.getChildAt(0);
    ll2.getChildAt(0).setVisibility(View.GONE);
    okBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
            Integer month = datePicker.getMonth() + 1;
            Integer year = datePicker.getYear();
            String expYear = year.toString();
            tvMonthYear.setText(month+ " " + expYear);
        }
    });
 cancelBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });
}

我认为除非你想定制它，否则你不需要那么深入。有：

mDatePicker.getDatePicker().setCalendarViewShown(false);

这是删除日历段的非常合法的调用。
