adapter = new CommodityRecommendationAdapter(this, datas);
rv_commodity_recommendation.setLayoutManager(new GridLayoutManager(this,2));
rv_commodity_recommendation.setAdapter(adapter);
adapter.notifyDataSetChanged();
适配器:
public class CommodityRecommendationAdapter extends RecyclerView.Adapter<CommodityRecommendationAdapter.CommodityViewHolder> {
private Context context;
private List<CommodityRecommendation> datas = new ArrayList<>();
public CommodityRecommendationAdapter(Context context, List<CommodityRecommendation> datas) {
super();
this.context = context;
this.datas = datas;
}
@Override
public CommodityViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.commodityrecommendation_item,null);
CommodityViewHolder thirdViewHolder = new CommodityViewHolder(view);
return thirdViewHolder;
}
@Override
public void onBindViewHolder(CommodityViewHolder holder, int position) {
holder.tv_productname.setText(datas.get(position).getProductname());
holder.tv_price.setText("¥"+datas.get(position).getPrice());
holder.tv_commodity_price.setText("¥"+datas.get(position).getCommodity_price());
}
@Override
public int getItemCount() {
return datas.size();
}
class CommodityViewHolder extends RecyclerView.ViewHolder{
TextView tv_productname;
TextView tv_price;
TextView tv_commodity_price;
public CommodityViewHolder(View itemView) {
super(itemView);
tv_productname = (TextView) itemView.findViewById(R.id.tv_productname);
tv_price = (TextView) itemView.findViewById(R.id.tv_price);
tv_commodity_price = (TextView) itemView.findViewById(R.id.tv_commodity_price);
}
