public class FavoritRecyclerViewAdapter extends RecyclerView.Adapter<FavoritRecyclerViewAdapter.ViewHolder> {

    private Context context;
    private List<Favorit> favoritList;

    public FavoritRecyclerViewAdapter(Context context, List<Favorit> favoritList) {
        this.context = context;
        this.favoritList = favoritList;
    }

    @Override
    public FavoritRecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.favorit_row, parent, false);
        return new ViewHolder(view, context);
    }


    @Override
    public void onBindViewHolder(final FavoritRecyclerViewAdapter.ViewHolder holder, int position) {
        Favorit favorit = favoritList.get(position);

        holder.titleIDfav.setText(favorit.getGajiFav());
        holder.lokasiIDfav.setText(favorit.getLokasiFav());
        holder.gajiIDfav.setText(favorit.getGajiFav());

        String img_logoFavUrl = favorit.getImg_logoFav();
        Glide.with(context)
                .load(img_logoFavUrl)
                .apply(new RequestOptions()
//                                .placeholder(android.R.drawable.ic_dialog_info)

                )
                .into(holder.img_logoFav);

        holder.buttonViewOption.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //creating a popup menu
                PopupMenu popup = new PopupMenu(context, holder.buttonViewOption);
                //inflating menu from xml resource
                popup.inflate(R.menu.fav_options_menu);
                //adding click listener
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {

                            case R.id.menu1:
                                //handle menu1 click
                                break;
                            case R.id.menu2:
                                //handle menu2 click
                                break;

//                            case R.id.menu3:

//                                break;
                        }
                        return false;
                    }
                });
                //displaying the popup
                popup.show();
            }
        });

    }

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

    class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

        private ImageView img_logoFav;
        private TextView titleIDfav;
        private TextView lokasiIDfav;
        private TextView gajiIDfav;

        ViewHolder(View itemView, final Context ctx) {
            super(itemView);
            context = ctx;

            img_logoFav = itemView.findViewById(R.id.img_logoFav);
            titleIDfav = itemView.findViewById(R.id.titleIDfav);
            lokasiIDfav = itemView.findViewById(R.id.lokasiIDFav);

Answer 2

尝试使用POPUP_MENU！

在我的知识选项菜单中应该首选菜单栏。并且对于长按使用上下文菜单和适配器项目，您应该去弹出菜单

试试这个Android文档here
