目前我正在使用日期选择器本机，但我想以这样的方式更改它，我只需要一个月和一年 如何修改我的代码是
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
return new DatePickerDialog(this, datePickerListener,
year, month,day);
}
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener
= new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
/* year = selectedYear;
month = selectedMonth;
day = selectedDay;*/
mynewYear=selectedYear;
myNewMonth=selectedMonth;
myNewDay=selectedDay;
try {
checkDate();
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
/*time_date_TV.setText(new StringBuilder()
.append(myNewMonth + 1).append("/")
.append(myNewDay ).append("/").append(mynewYear));
*/
}
};
我只想隐藏日期部分任何帮助都将被感谢完整

脑力激荡半天后，我找到了这个解决方案，这可能有助于其他有这种情况
我的日期选择器的自定义类是以下每次用户更改月/年时将更新标题中的日期
class CustomDatePickerDialog extends DatePickerDialog implements OnDateChangedListener {
private DatePickerDialog mDatePicker;
@SuppressLint("NewApi")
public CustomDatePickerDialog(Context context,int theme, OnDateSetListener callBack,
int year, int monthOfYear, int dayOfMonth) {
super(context, theme,callBack, year, monthOfYear, dayOfMonth);
mDatePicker = new DatePickerDialog(context,theme,callBack, year, monthOfYear, dayOfMonth);
mDatePicker.getDatePicker().init(2013, 7, 16, 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);
// mCalendar.set(Calendar.DAY_OF_MONTH, day);
mDatePicker.setTitle(getFormat().format(mCalendar.getTime()));
}
public DatePickerDialog getPicker(){
return this.mDatePicker;
}
/*
* the format for dialog tile,and you can override this method
*/
public SimpleDateFormat getFormat(){
return new SimpleDateFormat("MMM, yyyy");
};
}
以下是将日期选择器对话框
隐藏日期及其微调器的代码CustomDatePickerDialog dp = new CustomDatePickerDialog(context, android.R.style.Theme_Holo_Light_Dialog, datePickerListener, year, month, day);
DatePickerDialog obj = dp.getPicker();
try{
Field[] datePickerDialogFields = obj.getClass().getDeclaredFields();
for (Field datePickerDialogField : datePickerDialogFields) {
if (datePickerDialogField.getName().equals("mDatePicker")) {
datePickerDialogField.setAccessible(true);
DatePicker datePicker = (DatePicker) datePickerDialogField.get(obj);
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);
}
}
}
}
}catch(Exception ex){
}
obj.show();

简单地说 - 只是在datePickerDialog中隐藏NumberPicker 这是我项目的代码
public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, c.get(Calendar.YEAR),
c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
dialog.getDatePicker().setSpinnersShown(true);
// hiding calendarview and daySpinner in datePicker
dialog.getDatePicker().setCalendarViewShown(false);
LinearLayout pickerParentLayout = (LinearLayout) dialog.getDatePicker().getChildAt(0);
LinearLayout pickerSpinnersHolder = (LinearLayout) pickerParentLayout.getChildAt(0);
pickerSpinnersHolder.getChildAt(0).setVisibility(View.GONE);
dialog.setTitle("Pick a date");
return dialog;
}
public void onDateSet(DatePicker view, int yy, int mm, int dd) {
Calendar result = Calendar.getInstance();
result.set(Calendar.YEAR, yy);
result.set(Calendar.MONDAY, mm);
result.set(Calendar.DAY_OF_MONTH, dd);
if (currentWeek != -1) {
updateDateWeek(result.getTimeInMillis());
} else {
updateDate(result.getTimeInMillis());
}
}
}
显示选择器只需致电
DialogFragment newFragment = new SelectDateFragment();
newFragment.show(getActivity().getSupportFragmentManager(), "DatePicker");

这可能对你有用..如果你只做英文..也可以根据要求进行修改。
Locale.setDefault(Locale.UK);
这将使日期选择器以DD / MM / YYYY
的形式出现以下代码会删除日期分页器
LinearLayout pickerParentLayout =
(LinearLayout) mDatePicker.getChildAt(0);
LinearLayout pickerSpinnersHolder = (LinearLayout) pickerParentLayout.getChildAt(0);
NumberPicker picker = (NumberPicker) pickerSpinnersHolder.getChildAt(0);
picker.setVisibility(View.GONE);

在尝试了几种不同的方法后，这对我有用。
datePicker = (DatePicker) findViewById(R.id.date_picker);
public void hideDay() {
try {
java.lang.reflect.Field[] f = datePicker.getClass().getDeclaredFields();
for (java.lang.reflect.Field field : f) {
if (field.getName().equals("mDayPicker") || field.getName().equals("mDaySpinner")) {
field.setAccessible(true);
Object dmPicker = new Object();
dmPicker = field.get(datePicker);
((View) dmPicker).setVisibility(View.GONE);
}
}
}
catch (SecurityException e) {
TLog.d("ERROR", e.getMessage());
}
catch (IllegalArgumentException e) {
TLog.d("ERROR", e.getMessage());
}
catch (IllegalAccessException e) {
TLog.d("ERROR", e.getMessage());
}
}

我修改了一些东西，比如： 制作风格的android默认Theme_Holo_Dialog并从可见性中删除当天。
我的代码经过少量更改后：
pick_expire_date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Get Current Date
final Calendar c = Calendar.getInstance();
cyear = c.get(Calendar.YEAR);
cmonth = c.get(Calendar.MONTH);
cday = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(
CheckoutPaymentActivity.this,
android.R.style.Theme_Holo_Dialog,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
pick_expire_date.setText((monthOfYear + 1)+"/"+year);
mMonth = monthOfYear + 1;
mYear = year;
}
},
cyear, cmonth, cday);
datePickerDialog.getDatePicker().findViewById(getResources().getIdentifier("day","id","android")).setVisibility(View.GONE);
datePickerDialog.show();
}
});

这对我有用：）
DatePickerDialog datePickerDialog =
new DatePickerDialog(getActivity(), AlertDialog.THEME_HOLO_DARK,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view,
int year,
int monthOfYear,
int dayOfMonth) {
txtMonth.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
}
}, mYear, mMonth, mDay);
((ViewGroup)datePickerDialog.getDatePicker())
.findViewById(Resources.getSystem().getIdentifier("day", "id", "android"))
.setVisibility(View.GONE);
datePickerDialog.show();
