Android RecyclerView：通过接口回调为列表项实现独立点击事件

public class AdafruitFeedAdapter extends RecyclerView.Adapter<AdafruitFeedAdapter.ViewHolder> { // 注意类名应使用PascalCase

    // 定义一个公共接口，用于处理点击事件
    public interface OnItemClickListener {
        void onItemClick(FeedData data, int position);
    }

    private ArrayList<FeedData> feedDataList;
    private OnItemClickListener clickListener; // 持有接口实例

    // 修改构造函数，接收接口实例
    public AdafruitFeedAdapter(ArrayList<FeedData> feedDataList, OnItemClickListener clickListener) {
        this.feedDataList = feedDataList;
        this.clickListener = clickListener;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_feed, parent, false);
        // 在创建ViewHolder时，将clickListener传递给它
        return new ViewHolder(v, clickListener);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.setData(feedDataList.get(position));
    }

    @Override
    public int getItemCount() {
        return feedDataList.size();
    }

    // ViewHolder的实现
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        Button btnMisFeeds;
        FeedData dataHolder;
        private OnItemClickListener viewHolderClickListener; // ViewHolder内部持有的接口实例

        public ViewHolder(@NonNull View itemView, OnItemClickListener clickListener) {
            super(itemView);
            this.viewHolderClickListener = clickListener; // 保存传入的接口实例
            btnMisFeeds = itemView.findViewById(R.id.btnMisFeeds);
            btnMisFeeds.setOnClickListener(this); // 设置按钮的点击监听器为ViewHolder自身
        }

        public void setData(FeedData feedData) {
            dataHolder = feedData;
            btnMisFeeds.setText(dataHolder.getName());
        }

        @Override

            if (viewHolderClickListener != null) {
                // 使用getBindingAdapterPosition()获取可靠的当前项位置
                viewHolderClickListener.onItemClick(dataHolder, getBindingAdapterPosition());
            }
        }
