推荐答案

您应该实现OnItemClickListener在ViewHolder类和当前项目传递给viewholder实例上的每个onBindViewHolder（）。

You should implement the OnItemClickListener in your ViewHolder class, and pass the current item to the viewholder instances on every onBindViewHolder().

从这个帖子：

public static class ViewHolder extends RecyclerView.ViewHolder {
    public View view;
    public Item currentItem;

    public ViewHolder(View v) {
        super(v);
        view = v;
        view.setOnClickListener(new View.OnClickListener() {
            @Override public void onClick(View v) {
                // item clicked
            }
        });
    }
}

@Override public void onBindViewHolder(ViewHolder viewHolder, int i) {
    viewHolder.currentItem = items.get(i);
}
