仅包含日期和月份的Android日期选择器

世事洞明皆学问，人情练达即文章。这篇文章主要讲述仅包含日期和月份的Android日期选择器相关的知识，希望能为你提供帮助。
我正在寻找一种方法来自定义android中的日期选择器，只显示日期和月份（即没有年份）。
我正在创建一个基于How to display date picker for android with only month and year fields?的对话框：

Dialog dlg = new DatePickerDialog(context, datePickerListener, dueDateCalendar.get(Calendar.YEAR), dueDateCalendar.get(Calendar.MONTH), dueDateCalendar.get(Calendar.DAY_OF_MONTH)); try { Field f[] = dlg.getClass().getDeclaredFields(); for (Field field : f) { String name = field.getName(); if (name.equals("YEAR")){ field.setAccessible(true); Object dayPicker = new Object(); dayPicker = field.get(dlg); ((View) dayPicker).setVisibility(View.GONE); } } } catch (Exception e){ // TODO: should not happen e.printStackTrace(); } return dlg;

但我一直在（（查看）dayPicker）.setVisibility（View.GONE）上获得Cast异常;

java.lang.ClassCastException：java.lang.String无法强制转换为android.view.View

有任何想法吗？
答案【仅包含日期和月份的Android日期选择器】在这里一试。它的APIv11 +但是在较低的API版本上还有其他方法。

DatePickerDialog dlg = new DatePickerDialog(context, datePickerListener, dueDateCalendar.get(Calendar.YEAR), dueDateCalendar.get(Calendar.MONTH), dueDateCalendar.get(Calendar.DAY_OF_MONTH)); int year = context.getResources().getIdentifier("android:id/year", null, null); if(year != 0){ View yearPicker = dlg.getDatePicker().findViewById(year); if(yearPicker != null){ yearPicker.setVisibility(View.GONE); } } return dlg;

更新的代码：这应该可以胜任。

DatePickerDialog dlg = new DatePickerDialog(context, datePickerListener, dueDateCalendar.get(Calendar.YEAR), dueDateCalendar.get(Calendar.MONTH), dueDateCalendar.get(Calendar.DAY_OF_MONTH)) { @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;

另一答案这对我有用：

DatePickerDialog monthDatePickerDialog = new DatePickerDialog(activity, AlertDialog.THEME_HOLO_LIGHT, new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) { monthTextView.setText(dayOfMonth+ "/" + (month + 1)); } }, yearNow, monthNow, dayNow){ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getDatePicker().findViewById(getResources().getIdentifier("year","id","android")).setVisibility(View.GONE); } }; monthDatePickerDialog.setTitle("select_month"); monthDatePickerDialog.show();
