Answer 1

显然，这是CalendarView代码中的一个错误。这是对bug的引用。这不是一个真正的答案，而是更多的解释，我想。

据称，它已在4.2中修复。

Answer 2

如果有人仍然感兴趣，这是我的解决方案，基于Phil的帖子和XSJoJo的报告中提供的信息。如上所述，问题出现了，因为mDateTextSize未分配给mMonthNumDrawPaint中的CalendarViewLegacyDelegate。我正在使用Java反射。

    /**
     * I'm doing this in my fragment's onCreateView() callback
     */

    CalendarView calendarView = (CalendarView) contentView.findViewById(R.id.calendar_view);

    if (Build.VERSION.SDK_INT == Build.VERSION_CODES.JELLY_BEAN) { // this bug exists only in Android 4.1
        try {
            Object object = calendarView;
            Field[] fields = object.getClass().getDeclaredFields();
            for (Field field : fields) {
                if (field.getName().equals("mDelegate")) { // the CalendarViewLegacyDelegate instance is stored in this variable
                    field.setAccessible(true);
                    object = field.get(object);

                    break;
                }
            }

            Field field = object.getClass().getDeclaredField("mDateTextSize"); // text size integer value
            field.setAccessible(true);
            final int mDateTextSize = (Integer) field.get(object);

            field = object.getClass().getDeclaredField("mListView"); // main ListView
            field.setAccessible(true);
            Object innerObject = field.get(object);

            Method method = innerObject.getClass().getMethod(
                    "setOnHierarchyChangeListener", ViewGroup.OnHierarchyChangeListener.class); // we need to set the OnHierarchyChangeListener
            method.setAccessible(true);
            method.invoke(innerObject, (Object) new ViewGroup.OnHierarchyChangeListener() {
                @Override
                public void onChildViewAdded(View parent, View child) { // apply text size every time when a new child view is added
                    try {
                        Object object = child;
                        Field[] fields = object.getClass().getDeclaredFields();
                        for (Field field : fields) {
                            if (field.getName().equals("mMonthNumDrawPaint")) { // the paint is stored inside the view
                                field.setAccessible(true);
                                object = field.get(object);
                                Method method = object.getClass().
                                        getDeclaredMethod("setTextSize", float.class); // finally set text size
                                method.setAccessible(true);
                                method.invoke(object, (Object) mDateTextSize);

                                break;
                            }
                        }
                    } catch (Exception e) {
                        Log.e(APP_TAG, e.getMessage(), e);
                    }
                }

                @Override
                public void onChildViewRemoved(View parent, View child) {}
            });
        } catch (Exception e) {
            Log.e(APP_TAG, e.getMessage(), e);
        }
    }
