提问by user3160725
I have a DatePickerDialog and I want view only Month and Year. How can I change this code?
我有一个 DatePickerDialog，我只想查看月和年。如何更改此代码？
public void chooseDate2(View v) {
new DatePickerDialog(
act.this,
d1,
dateAndTime1.get(Calendar.YEAR) + 2,
dateAndTime1.get(Calendar.MONTH),
dateAndTime1.get(Calendar.DAY_OF_MONTH)
).show();
}
private void updateLabel2() {
scadenza.setText(fmtDateAndTime.format(dateAndTime1.getTime()));
}
DatePickerDialog.OnDateSetListener d1=new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
dateAndTime1.set(Calendar.YEAR, year);
dateAndTime1.set(Calendar.MONTH, monthOfYear);
dateAndTime1.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel2();
}
};
Thanks
谢谢

Try the following code. It will show a DatePickerwith only the year and month (without day)
试试下面的代码。它将显示DatePicker只有年和月（没有日）
private DatePickerDialog createDialogWithoutDateField() {
DatePickerDialog dpd = new DatePickerDialog(this, null, 2014, 1, 24);
try {
java.lang.reflect.Field[] datePickerDialogFields = dpd.getClass().getDeclaredFields();
for (java.lang.reflect.Field datePickerDialogField : datePickerDialogFields) {
if (datePickerDialogField.getName().equals("mDatePicker")) {
datePickerDialogField.setAccessible(true);
DatePicker datePicker = (DatePicker) datePickerDialogField.get(dpd);
java.lang.reflect.Field[] datePickerFields = datePickerDialogField.getType().getDeclaredFields();
for (java.lang.reflect.Field datePickerField : datePickerFields) {
Log.i("test", datePickerField.getName());
if ("mDaySpinner".equals(datePickerField.getName())) {
datePickerField.setAccessible(true);
Object dayPicker = datePickerField.get(datePicker);
((View) dayPicker).setVisibility(View.GONE);
}
}
}
}
}
catch (Exception ex) {
}
return dpd;
}
This method returns a date picker dialog. So , in your button's onClickmethod add the following code to display your dialog.
此方法返回一个日期选择器对话框。因此，在您的按钮onClick方法中添加以下代码以显示您的对话框。
createDialogWithoutDateField().show();

As i recently stumbled across this problem myself, i tested multiple solutions from this post and similar questions on Stackoverflow.
由于我最近自己偶然发现了这个问题，因此我测试了这篇文章中的多个解决方案以及 Stackoverflow 上的类似问题。
Unfortunately i found no working solution especially for Android 5+
不幸的是，我没有找到特别适用于 Android 5+ 的有效解决方案
I ended up with implementing my own simple DialogFragment embedding two NumberPickers. This should be compatible with all versions from 3.0 and upwards.
我最终实现了我自己的简单 DialogFragment 嵌入两个 NumberPickers。这应该与 3.0 及更高版本的所有版本兼容。
Here is the code:
这是代码：
public class MonthYearPickerDialog extends DialogFragment {
private static final int MAX_YEAR = 2099;
private DatePickerDialog.OnDateSetListener listener;
public void setListener(DatePickerDialog.OnDateSetListener listener) {
this.listener = listener;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
Calendar cal = Calendar.getInstance();
View dialog = inflater.inflate(R.layout.date_picker_dialog, null);
final NumberPicker monthPicker = (NumberPicker) dialog.findViewById(R.id.picker_month);
final NumberPicker yearPicker = (NumberPicker) dialog.findViewById(R.id.picker_year);
monthPicker.setMinValue(0);
monthPicker.setMaxValue(11);
monthPicker.setValue(cal.get(Calendar.MONTH));
int year = cal.get(Calendar.YEAR);
yearPicker.setMinValue(year);
yearPicker.setMaxValue(MAX_YEAR);
yearPicker.setValue(year);
builder.setView(dialog)
// Add action buttons
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
listener.onDateSet(null, yearPicker.getValue(), monthPicker.getValue(), 0);
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
MonthYearPickerDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
And the layout
和布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="horizontal">
<NumberPicker
android:id="@+id/picker_month"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="20dp"
android:layout_marginRight="20dp">
</NumberPicker>
<NumberPicker
android:id="@+id/picker_year"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</NumberPicker>
</LinearLayout>
</LinearLayout>
To show the layout use:
要显示布局使用：
MonthYearPickerDialog pd = new MonthYearPickerDialog();
pd.setListener(this);
pd.show(getFragmentManager(), "MonthYearPickerDialog");

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.
In addition it does not work on API LEVEL >= 21.
此外，它不适用于 API LEVEL >= 21。

As I have a requirement to make Year optional. And I have also handled date like february 28and also handle leap year.
因为我需要将Year设为optional。而且我也处理过像2 月 28日这样的日期，也处理过闰年。

The answer by 'Xar E Ahmer' is very easy to follow and as per requirement. I have used the same with following modifications as per my requirement.
'Xar E Ahmer' 的回答很容易理解，而且符合要求。我根据我的要求使用了相同的内容并进行了以下修改。
- Kotlin conversion of 'Xar E Ahmer' Answer .
- Few error handling case added.
- More handing of February 28/29 as per leap year.
- Every year checkbox to exclude year ( simplified for user ).
- 'Xar E Ahmer' 答案的 Kotlin 转换。
- 添加了一些错误处理案例。
- 按闰年更多处理 2 月 28 日/29 日。
- 每年复选框以排除年份（为用户简化）。

For the users, who wanted 'date' object as returned value:-
对于想要“日期”对象作为返回值的用户：-
we can create date object from the returned day, Month and Year values as per following ( please correct any syntax error )
我们可以根据以下返回的日、月和年值创建日期对象（请更正任何语法错误）
SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
String currentDateString = selectedDay + "-" selectedMonth + "-" + selectedYear;
long millis = format.parse(currentDateString).getTime();
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis( millis );
int date = calendar.get(CALENDAR.DATE);

This is an old question, but now you can just use "BetterPickers":
这是一个老问题，但现在您可以使用“BetterPickers”：

And use ExpirationPicker.
并使用 ExpirationPicker。
Hope this solves it for some other lost souls who searched Google far and wide.
