如何在运行时在回收器视图中进行结构更改。 用于添加点击喜欢的功能

Question

I want to make Facebook or Instagram like RecyclerView . The problem comes when the user taps the like button, no visual changes occur.

notifyItemChanged() changes the whole data set after that position.

Answer 1

You shouldn't notify adapter that all data changed when you actually changed one item. Use void notifyItemChanged (int position, Object payload) on specific item position and then you can retrieve it in void onBindViewHolder (VH holder, int position, List<Object> payloads)
