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;
}
Use the above code for hiding the day field in DatePickerDialog.

I don't recommend using Reflection to do this kind of thing.
我不建议使用反射来做这种事情。
There is a simpler and more pretty way to do so:
有一种更简单、更漂亮的方法来做到这一点：
((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);
Be aware that .getDatePicker()method from DatePickerDialogworks on API LEVEL >= 11.
请注意，该.getDatePicker()方法DatePickerDialog适用于API LEVEL >= 11.

final Dialog dialog = new Dialog(context);

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);
}
});
}
This code works and hides the day in a DatePicker, so I can show Expiry Date for Cards. Enjoy!!
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！！

I don't think you need to go that deep unless you wanna customize it.. there is the :
我不认为你需要深入，除非你想定制它..有：
mDatePicker.getDatePicker().setCalendarViewShown(false);
which is a very legitimate call to remove the calendar segment.
这是删除日历段的非常合理的调用。
