在创建一个URLs类：
public class URLs {
public static final String SHANGPIN = "http://120.27.23.105/product/searchProducts";
}
创建一个bean包\包里有两个bean
一个是BJBean类：

public void onCreate() {

ImageLoaderConfiguration defaultcof = ImageLoaderConfiguration.createDefault(getApplicationContext());
ImageLoader.getInstance().init(defaultcof);

//主线程处理
public abstract void onFailed(Call call, IOException e);

Gson gson = new Gson();
final T t = gson.fromJson(json, cls);
handler.post(new Runnable() {
@Override
public void run() {
onUi(t);
}
});
}
}
创建adapter包，里面有两个适配器
第一个适配器是XRecAdapterBJB
public class XRecAdapterBJB extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List bjbList;
private MainActivity mainActivity;
public XRecAdapterBJB(List bjbList, MainActivity mainActivity) {
this.mainActivity = mainActivity;
this.bjbList = bjbList;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = View.inflate(mainActivity, R.layout.xrecview, null);
XRecViewHolder xRecViewHolder = new XRecViewHolder(view);
return xRecViewHolder;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
XRecViewHolder xRecViewHolder = (XRecViewHolder) holder;
xRecViewHolder.titel.setText(bjbList.get(position).getTitle());
xRecViewHolder.yj.setText(bjbList.get(position).getBargainPrice() + "");
xRecViewHolder.xj.setText(bjbList.get(position).getPrice() + "");
String[] picUrl = bjbList.get(position).getImages().split("\\|");
Glide.with(mainActivity).load(picUrl[0]).into(xRecViewHolder.iv);
}
@Override
public int getItemCount() {
return bjbList != null ? bjbList.size() : 0;
}
class XRecViewHolder extends RecyclerView.ViewHolder {
private final ImageView iv;
private final TextView titel;
private final TextView yj;
private final TextView xj;
public XRecViewHolder(View itemView) {
super(itemView);
iv = itemView.findViewById(R.id.xRecView_itemsj_iv);
titel = itemView.findViewById(R.id.xRecView_itemsj_titel);
yj = itemView.findViewById(R.id.xRecView_itemsj_yuanJia);
xj = itemView.findViewById(R.id.xRecView_itemsj_xianJia);
}
}
}
第二个XRecAdapterSJ类
public class XRecAdapterSJ extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List sjList;
private MainActivity mainActivity;
public XRecAdapterSJ(List sjList, MainActivity mainActivity) {
this.mainActivity = mainActivity;
this.sjList = sjList;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = View.inflate(mainActivity,R.layout.xrecview,null);
XRecViewHolder xRecViewHolder = new XRecViewHolder(view);
return xRecViewHolder;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
XRecViewHolder xRecViewHolder = (XRecViewHolder) holder;
xRecViewHolder.titel.setText(sjList.get(position).getTitle());
xRecViewHolder.yj.setText(sjList.get(position).getBargainPrice()+"");
xRecViewHolder.xj.setText(sjList.get(position).getPrice()+"");
String[] picUrl = sjList.get(position).getImages().split("\\|");
Glide.with(mainActivity).load(picUrl[0]).into(xRecViewHolder.iv);
}
@Override
public int getItemCount() {
return sjList != null ? sjList.size() : 0;
}
class XRecViewHolder extends RecyclerView.ViewHolder {
private final ImageView iv;
private final TextView titel;
private final TextView yj;
private final TextView xj;
public XRecViewHolder(View itemView) {
super(itemView);
iv = itemView.findViewById(R.id.xRecView_itemsj_iv);
titel = itemView.findViewById(R.id.xRecView_itemsj_titel);
yj = itemView.findViewById(R.id.xRecView_itemsj_yuanJia);
xj = itemView.findViewById(R.id.xRecView_itemsj_xianJia);
}
}
}
