BaseSkinActivity#onCreateView中为什么用反射来创建 view？

[KennethYo]

 try
        {
            //public View createView
            // (View parent, final String name, @NonNull Context context, @NonNull AttributeSet attrs)
            if (sCreateViewMethod == null)
            {
                Method methodOnCreateView = delegate.getClass().getMethod("createView", sCreateViewSignature);
                sCreateViewMethod = methodOnCreateView;
            }
            Object object = sCreateViewMethod.invoke(delegate, parent, name, context, attrs);
            view = (View) object;
        } catch (NoSuchMethodException e)
        {
            e.printStackTrace();
        } catch (InvocationTargetException e)
        {
            e.printStackTrace();
        } catch (IllegalAccessException e)
        {
            e.printStackTrace();
        }

这里的代码为什么用发射创建而不是用 直接调用delegate.createView 呢？如下

 view = delegate.createView(parent, name, context, attrs);

我猜测是作者怕哪个版本的createView方法变成private，就不能调用了，用反射保险一些 不知道猜的对不对，请HongYang兄解惑一下:)

搞不懂为什么要实现createView这个部分，应该只需要解析attrs就好了。createView还是由父类完成就好了？ @Override public View onCreateView(View parent, String name, Context context, AttributeSet attrs) { View view = super.onCreateView(parent, name, context, attrs); List<SkinAttr> skinAttrList = SkinAttrSupport.getSkinAttrs(attrs, context); if (skinAttrList.isEmpty()) { return view; } if (view == null) { view = createViewFromTag(context, name, attrs); } injectSkin(view, skinAttrList); return view;
