For instance, you have an adapter and in onBindViewHolder method you set OnClickListener to some views (and do some actions there depending on view position). You should assign final to position param of method onBindViewHolder so it could be accessible from onClick().

After changing dataset (remove or add item in list) you call onItemInserted or onItemRemoved and this really adds/removes a view in the recyclerview, BUT it does not refresh other viewitems so when you click on a neighbor viewitem it will open a screen or show data with invalid index. To avoid this I basically call notifyDatasetChanged to call onBind to all visible views and remove/add some views.

So how to refresh other views when you call notifyItemInserted/removed or how to work with these methots appropriately?

I advise you to add notifyItemRangeChanged after insert or remove list inside adapter. This work for my project.

Example in remove item :

public void removeItem (int pos) {        
        simpanList.remove(pos);
        notifyItemRemoved(pos);
        notifyItemRangeChanged(pos, simpanList.size());//add here, this can refresh position cmiiw
    }
