据我所知，MLProgrammer-CiM的答案很简单，可以这样做:

class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    private ImageView image;
    private TextView title;
    private TextView price;

    public MyViewHolder(View itemView) {
        super(itemView);
        image = (ImageView)itemView.findViewById(R.id.horizontal_list_image);
        title = (TextView)itemView.findViewById(R.id.horizontal_list_title);
        price = (TextView)itemView.findViewById(R.id.horizontal_list_price);
        image.setOnClickListener(this);
        title.setOnClickListener(this);
        price.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        Toast.makeText(context, "Item click nr: "+getLayoutPosition(), Toast.LENGTH_SHORT).show();
    }
}

Recyclerview动画没有经过测试，其他正常。我认为它已经优化到最大。接口有其他用途，可以暂时忽略。

public abstract class BaseAdapterRV<VH extends BaseViewHolder> extends RecyclerView.Adapter<VH> implements AdapterInterface {
    public final String TAG = getClass().getSimpleName();

    protected final Activity mActivity;
    protected final LayoutInflater mInflater;
    protected ItemClickInterface<?, Integer> mListener;

    public BaseAdapterRV(Activity activity) {
        mActivity = activity;
        mInflater = LayoutInflater.from(mActivity);
    }

    @Override
    public final VH onCreateViewHolder(ViewGroup parent, int viewType) {
        return onCreateViewHolder(parent, viewType, mInflater);
    }

    @Override
    public final void onBindViewHolder(VH holder, int position) {
        holder.itemView.setTag(R.id.tag_view_click, position);
        //创建点击事件
        holder.itemView.setOnClickListener(mListener);
        holder.itemView.setOnLongClickListener(mListener);
        onBindVH(holder, position);
    }


    ///////////////////////////////////////////////////////////////////////////
    // 以下是增加的方法
    ///////////////////////////////////////////////////////////////////////////

    /**
     * 注意!涉及到notifyItemInserted刷新时立即获取position可能会不正确
     * 里面也有onItemLongClick
     */
    public void setOnItemClickListener(ItemClickInterface<?, Integer> listener) {
        mListener = listener;
        notifyDataSetChanged();
    }

    @NonNull
    protected abstract VH onCreateViewHolder(ViewGroup parent, int viewType, LayoutInflater inflater);

    protected abstract void onBindVH(VH holder, int position);

}

这是接口

/**
 * OnItemClickListener的接口
 * 见子类实现{@link OnItemClickListener}{@link OnItemItemClickListener}
 */
public interface ItemClickInterface<DATA1, DATA2> extends View.OnClickListener, View.OnLongClickListener {

    void onItemClick(DATA1 data1, DATA2 data2);

    boolean onItemLongClick(DATA1 data1, DATA2 data2);
}

这是一个抽象类

public abstract class OnItemClickListener<DATA> implements ItemClickInterface<View, DATA> {
    @Override
    public void onClick(View v) {
        onItemClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onLongClick(View v) {
        return onItemLongClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onItemLongClick(View view, DATA data) {
        return false;
    }
}

你只需要它

    mAdapter.setOnItemClickListener(new OnItemClickListener<Integer>() {
        @Override
        public void onItemClick(View view, Integer integer) {

        }

        @Override
        public boolean onItemLongClick(View view, Integer integer) {
            return true;
        }
    });

访问rowLayout(cell)的mainView为你的RecyclerView和在你的OnBindViewHolder写以下代码:

    @Override
    public void onBindViewHolder(MyViewHolder holder, final int position) {
        Movie movie = moviesList.get(position);
        holder.mainView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                System.out.println("pos " + position);
            }
        });
    }

在阅读了@MLProgrammer-CiM的回答后，以下是我的代码:

class NormalViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

    @Bind(R.id.card_item_normal)
    CardView cardView;

    public NormalViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);
        cardView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if(v instanceof CardView) {
            // use getAdapterPosition() instead of getLayoutPosition()
            int itemPosition = getAdapterPosition();
            removeItem(itemPosition);
        }
    }
}

我发现了使用androidx生命周期可变实时数据的最短方法之一

适配器:

private val onItemClickListener = MutableLiveData<YourAdapterItem>()


override fun onBindViewHolder(holder: GifsViewHolder, position: Int) {
    holder.itemView.setOnClickListener { onItemClickListener.value = gifs[position] }
}
fun getOnItemClickListener(): MutableLiveData<Gif> {
    return onItemClickListener
}

MainActivity的任何地方

    yourFancyAdapter.getOnItemClickListener().observe(this, Observer {
        println(it)
    })

这招对我很管用:

@Override
public void onBindViewHolder(PlacesListViewAdapter.ViewHolder holder, int position) {
    ----
    ----
    ----
    // Set setOnClickListener(holder);
}


@Override
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    ----
    ----
    ----

    @Override
    public void onClick(View view) {
        // Use to get the item clicked getAdapterPosition()
    }
}
