嘿家伙我有一个recyclerview适配器,它填充了cardview上的一些数据列表.我在卡片布局的右下角创建了一个三点菜单,它实际上会从recyclerview中删除卡片行,并且还会从存储行数据的sqlite数据库中删除该项目.问题是我无法弄清楚如何将实现删除的方法集成到recyclerview ViewHolder中.这是源代码

public class BeneficiaryRecyclerAdapter extends RecyclerView.Adapter<BeneficiaryRecyclerAdapter.BeneficiaryViewHolder> {

private List<Beneficiary> listBeneficiary;
public ImageView overflow;
private Context mContext;

public BeneficiaryRecyclerAdapter(){

}


public BeneficiaryRecyclerAdapter(List<Beneficiary> listBeneficiary, Context mContext) {
    this.listBeneficiary = listBeneficiary;
    this.mContext = mContext;

}


@Override
public BeneficiaryViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // inflating recycler item view
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_beneficiary_recycler, parent, false);

    return new BeneficiaryViewHolder(itemView);
}

@Override
public void onBindViewHolder(final BeneficiaryViewHolder holder, int position) {
    holder.textViewName.setText(listBeneficiary.get(position).getName());
    holder.textViewEmail.setText(listBeneficiary.get(position).getEmail());
    holder.textViewAddress.setText(listBeneficiary.get(position).getAddress());
    holder.textViewCountry.setText(listBeneficiary.get(position).getAddress());

    holder.overflow.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showPopupMenu(holder.overflow); …
