从日期选择器小部件中隐藏年份

我试图从日期选择器小部件中隐藏年份字段。这可能看起来像一个重复的问题，但之前问题给出的答案并不能帮助我隐藏年份字段。

这是我的代码：：

@Override 
protected void onCreate(Bundle savedInstanceState) {

    int month = 0;
    int year = 0;
    int day = 0;
    OnDateSetListener datePickerListener = null;
    CustomDatePickerDialog dp = new CustomDatePickerDialog(getBaseContext(), android.R.style.Theme_Holo_Light_Dialog,  datePickerListener, year, month, day);
    DatePickerDialog obj = dp.getPicker();

    picker = (DatePicker) findViewById(R.id.datePicker1);
    try {
          java.lang.reflect.Field[] f = obj.getClass().getDeclaredFields();
  //      Field f[] = picker.getClass().getDeclaredFields();
        for (java.lang.reflect.Field field : f) {
            if (field.getName().equals("prabs")) {
                field.setAccessible(true);
                DatePicker datePicker = (DatePicker) field.get(obj);
                java.lang.reflect.Field datePickerFields[] = obj.getClass().getDeclaredFields();
                for (java.lang.reflect.Field datePickerField : datePickerFields) {
                    if ("mYearPicker".equals(datePickerField.getName()) || "mYearSpinner".equals(datePickerField
                            .getName()))
                    {
                             datePickerField.setAccessible(true);
                             Object yearPicker = new Object();
                             yearPicker = datePickerField.get(datePicker);
                             ((View) yearPicker).setVisibility(View.GONE);
                    }
                }
           /*     Object yearPicker = new Object();
                yearPicker = field.get(picker);
                ((View) yearPicker).setVisibility(View.GONE);*/
            }
        }
    } 
    catch (SecurityException e) {
        Log.d("ERROR", e.getMessage());
    } 
    catch (IllegalArgumentException e) {
        Log.d("ERROR", e.getMessage());
    } 
    catch (IllegalAccessException e) {
        Log.d("ERROR", e.getMessage());
    }
    obj.show();
}

主类之外::

class CustomDatePickerDialog extends DatePickerDialog implements OnDateChangedListener
{
    private DatePickerDialog prabs;

    @SuppressLint("NewApi")
    public CustomDatePickerDialog(Context context, int theme,
            OnDateSetListener listener, int year, int monthOfYear,
            int dayOfMonth) 
    {
        super(context, theme, listener, year, monthOfYear, dayOfMonth);
        // TODO Auto-generated constructor stub
        prabs = new DatePickerDialog(context, theme, listener, year, monthOfYear, dayOfMonth);
        prabs.getDatePicker().init(2015, 01, 8, this);  
        updateTitle(monthOfYear,dayOfMonth);
    }

    private void updateTitle(int Month, int Day)
    {
        // TODO Auto-generated method stub
        Calendar mCalendar = Calendar.getInstance();
        mCalendar.set(Calendar.MONTH, Month);
        mCalendar.set(Calendar.DAY_OF_MONTH, Day);
        prabs.setTitle(getFormat().format(mCalendar.getTime()));
    }

    public SimpleDateFormat  getFormat() {
        // TODO Auto-generated method stub
        return new SimpleDateFormat("MMM, dd");
    }

    public void onDateChanged(DatePicker view,int year, int month,int day)
    {
        updateTitle(month,day);
    }

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

添加之前obj.show();它显示带有日历的整个小部件，但我只想要带有日期和月份的小部件

尝试解决这个问题已经很多天了。但每次都失败:( 任何建议都会有很大帮助。 谢谢..

EDIT::

年份字段表示日期选择器小部件的 Eclipse 年份字段

我提到如何仅在Android的日期选择器中显示年份 https://stackoverflow.com/questions/10793811/how-to-display-year-only-in-date-picker-in-android and 自定义日期选择器对话框 https://stackoverflow.com/questions/18249608/custom-date-picker-dialog

错误日志::

01-09 11:26:20.780: E/AndroidRuntime(23840): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application this is a crash report

试试这个，它对我有用。

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        // hide year from datepicker
        DatePickerDialog dlg = new DatePickerDialog(this,
                datePickerListener, year, month, day) {
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                int year = getContext().getResources().getIdentifier(
                        "android:id/year", null, null);
                if (year != 0) {
                    View yearPicker = findViewById(year);
                    if (yearPicker != null) {
                        yearPicker.setVisibility(View.GONE);
                    }
                }
            }
        };
        return dlg;
    }
    return null;
}
