Looking at the various methods I've used

问题 I have a RecyclerView with multiple item view types so they are broken into separate ViewHolder classes.

However, I separated the ViewHolders into different classes to better organize the code. Now, I cannot directly update my RecyclerView Adapter. Which of the following solutions is the best way to communicate from my ViewHolder to my
