我从另一个教程中复制并粘贴了这段代码,并根据自己的需要进行调整 . 我希望放入表的SQLite id,而不是通过适配器位置 . 我已经搜索了但是因为我对此很新,所以无论我尝试什么,都会让我感到困惑 .

谢谢你的帮助 .

公共类RecyclerAdapter扩展了RecyclerView.Adapter {

static   List<DatabaseModel> dbList;
static  Context context;
RecyclerAdapter(Context context, List<DatabaseModel> dbList ){
    this.dbList = new ArrayList<DatabaseModel>();
    this.context = context;
    this.dbList = dbList;

}

@Override public RecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType){

View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
            R.layout.item_row, null);

    // create ViewHolder

    ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}

@Override
public void onBindViewHolder(RecyclerAdapter.ViewHolder holder, int position) {

    Integer _id1= dbList.get(position).get_id();

    holder.address_h.setText(dbList.get(position).getAddress());
    holder.name_h.setText(dbList.get(position).getName());
    holder.date_h.setText(dbList.get(position).getSpare1()); // getDatetimedue needed
    holder.balance_h.setText("£" + dbList.get(position).getBalance());

    holder.address_h.setSelected(holder.address_h.isSelected());
    holder.balance_h.setSelected(holder.balance_h.isSelected());
    holder.name_h.setSelected(holder.name_h.isSelected());
    holder.date_h.setSelected(holder.date_h.isSelected());

}

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

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    public TextView address_h, balance_h, name_h, date_h;

    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        address_h = (TextView) itemLayoutView.findViewById(R.id.rvname);
        balance_h = (TextView)itemLayoutView.findViewById(R.id.rvphone);
        name_h = (TextView)itemLayoutView.findViewById(R.id.rvname_h);
        date_h = (TextView)itemLayoutView.findViewById(R.id.rvdate_h);


        itemLayoutView.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        Intent intent = new Intent(context,DetailsActivity.class);
        Bundle extras = new Bundle();


        extras.putInt("position",getAdapterPosition());
        intent.putExtras(extras);

        context.startActivity(intent);
    }
}

}
