推荐答案

你应该在你的 ViewHolder 类中实现 OnItemClickListener，并将当前项目传递给 ViewHolder 每个 onBindViewHolder() 上的实例.

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

来自这篇文章:

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);
}
