So zeigen Sie nur Jahr in Spinner

Question

Erstellen von App, in der ich nur Jahr in Spinner anzeigen möchte. Ich verwende DatepickerDialog, die Datum, Monat und Jahr zeigt, aber ich möchte nur Jahr anzeigen.

datePickerDialog = new DatePickerDialog(mContext, new DatePickerDialog.OnDateSetListener() { 

      @Override 
      public void onDateSet(DatePicker datePicker, int selectedYear, int selectedMonth, int selectedDate) { 

       datePicker = (DatePicker) findViewById(R.id.datePicker); 
       // datePicker.getYear(); 
       // year = selectedYear; 
       tvYearSelection.setText(new StringBuilder().append(datePicker.getYear())); 
      } 
     }, year, 0, 0); 

     datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis()); 
     datePickerDialog.show();

Wie wäre es damit?

private void 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); 
        } 

        if ("mMonthSpinner".equals(datePickerField.getName())) { 
         datePickerField.setAccessible(true); 
         Object dayPicker = datePickerField.get(datePicker); 
         ((View) dayPicker).setVisibility(View.GONE); 
        } 
       } 
      } 
     } 
    } 
    catch (Exception ex) { 
    } 
    dpd.show(); 
}
