在onBindViewHolder中获取对上一个项目的视图持有人引用

Question

I have a recycler view containing Image and share button in different block.

I need to find reference to view holder of Image when share button in different block is clicked.

Below is onBindViewHolder:

@Override
    public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {

switch (viewHolder.getItemViewType()) {

            case 49:
                MyViewHolder vh49 = (MyViewHolder) viewHolder;
                final ImageView z = vh1.rashifalFullImage;
                // .. more lines followed
                break;
            case 50:
                MyViewHolder vh50 = (MyViewHolder) viewHolder;
                // require reference to Imageview here
                // something like this final ImageView z = vh1.rashifalFullImage;
                break;
            default:
                break;
        }
    }

How can I achieve such a thing? Sorry for bad english.

您可以使用findViewHolderForAdapterPosition(int)直接通过RecyclerView进行操作：

ViewHolder holder = recyclerView.findViewHolderForAdapterPosition(49);
