一個標(biāo)準(zhǔn)的創(chuàng)建方法：
Object為你要adapter的類

class MyAdapter extends ListAdapter<Object, MyAdapter.MyViewHolder> {

    protected MyAdapter(@NonNull DiffUtil.ItemCallback<PhotoItem> diffCallback) {
        super(new DiffUtil.ItemCallback<Object>() { // 差異化比較
            @Override
            public boolean areItemsTheSame(@NonNull PhotoItem oldItem, @NonNull PhotoItem newItem) {
                return false; //比如oldItem.getId() == newItem.getId();比較Object里的id
            }

            @Override
            public boolean areContentsTheSame(@NonNull PhotoItem oldItem, @NonNull PhotoItem newItem) {
                return false; // 比如 (oldItem.getWord().equals(newItem.getWord()))
                        // &&(oldItem.getTranslate().equals(newItem.getTranslate()));
                         //比較Object里的word和translate
            }
        });
    }

    static class MyViewHolder extends RecyclerView.ViewHolder {
          // 這里定義ui組件
          // TextView tvNum;
        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            // 這里放ui組件
            // tvNum = itemView.findViewById(R.id.tv_num);
        }
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View itemView = inflater.inflate(R.layout.item_layout, parent, false); // 這里為item的layout
        MyViewHolder myViewHolder = new MyViewHolder(itemView);
        // 這里寫你要設(shè)置的監(jiān)聽器
        // 可以用tag的方式從下面取數(shù)據(jù)，比如：
        //  Word word = (Word) myViewHolder.itemView.getTag(R.id.word_tag); 
        // 也可以直接getItem獲得當(dāng)前顯示內(nèi)容的Object對象
        // Word word = getItem(myViewHolder.getAdapterPosition());
        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        // 這里就發(fā)揮你的想象力綁定ui控件了
        // 若有tag：
        // holder.itemView.setTag(R.id.word_tag ,word);
    }
}

Tag放values - id.xml:

<resources>
    <item name="word_tag" type="id"/>
</resources>

備份一個案例：
