自定义的Adapter

public class GoodAdapter extends RecyclerView.Adapter<GoodHolder> implements View.OnClickListener {
    Context context;
    List<GoodBean.DataBean> data;
    private OnItemClickListener onItemClickListener=null;


    public GoodAdapter(Context context, List<GoodBean.DataBean> data, OnItemClickListener onItemClickListener) {
        this.context=context;
        this.data=data;
        this.onItemClickListener=onItemClickListener;
    }

    @Override
    public GoodHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.good_list_layout, parent, false);
        GoodHolder goodHolder = new GoodHolder(view);
        view.setOnClickListener(this);

        return goodHolder;
    }

    @Override
    public void onBindViewHolder(GoodHolder holder, int position) {
        //赋值
        String[] split = data.get(position).getImages().split("\\|");
        //设置图片
        Glide.with(context).load(split[0]).into(holder.getImage());
        //设置标题
        holder.getText_title().setText(data.get(position).getTitle());
        //设置价格
        holder.text_price.setText("¥"+data.get(position).getPrice());
        //设置tag给回调的参数当中
        holder.itemView.setTag(position);

    }

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

    @Override
    public void onClick(View v) {

        onItemClickListener.onItemClick(v, (int) v.getTag());

    }


}

Avtivity

public class SearchActivity extends AppCompatActivity {

public OnItemClickListener onItemClickListener = new OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
        //i为当前条目

     } 
  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search);
    }

}

自定义接口

public interface OnItemClickListener {
    void onItemClick(View view , int position);
}
