在activity\_main.xml中的布局：

在创建一个Xrecview.xml布局：（适配器的item布局）

MainActivity :

public class MainActivity extends AppCompatActivity { 
    
        private boolean b = false;
        private boolean sjBJB = false;
        private ImageView qhIv;
        private EditText srkEdt;
        private XRecyclerView xRecView;
        private XRecAdapterSJ xRecAdapterSJ;
        private XRecAdapterBJB xRecAdapterBJB;
        private List<SJBean.DataBean> sjList;
        private List<BJBean.DataBean> bjbList;
        private String srkStr;
    
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
    
            initView();
            initDataSJ();
        }
    
        private void initDataBJB() {
            Map<String, String> mapBJB = new HashMap<>();
            mapBJB.put("keywords", "笔记本");
            mapBJB.put("page", "1");
            mapBJB.put("source", "2");
            OkHttp3Utils.doPost(URLs.SHANGPIN, mapBJB, new GsonObjectCallback<BJBean>() {
    
                @Override
                public void onUi(BJBean bjbBean) {
                    bjbList = bjbBean.getData();
                    xRecView.setLayoutManager(new LinearLayoutManager(MainActivity.this));
                    xRecAdapterBJB = new XRecAdapterBJB(bjbList, MainActivity.this);
                    xRecView.setAdapter(xRecAdapterBJB);
                }
    
                @Override
                public void onFailed(Call call, IOException e) {
    
                }
            });
        }
    
        private void initDataSJ() {
            Map<String, String> mapSJ = new HashMap<>();
            mapSJ.put("keywords", "手机");
            mapSJ.put("page", "1");
            mapSJ.put("source", "1");
            OkHttp3Utils.doPost(URLs.SHANGPIN, mapSJ, new GsonObjectCallback<SJBean>() {
    
                @Override
                public void onUi(SJBean sjBean) {
                    sjList = sjBean.getData();
                    xRecAdapterSJ = new XRecAdapterSJ(sjList, MainActivity.this);
                    xRecView.setLayoutManager(new LinearLayoutManager(MainActivity.this));
                    xRecView.setAdapter(xRecAdapterSJ);
                }
    
                @Override
                public void onFailed(Call call, IOException e) {
    
                }
            });
    
    
        }
    
        private void initView() {
            qhIv = (ImageView) findViewById(R.id.qieHuanIv);
            srkEdt = (EditText) findViewById(R.id.edt_shurukuang);
            xRecView = (XRecyclerView) findViewById(R.id.xRecView);
            initFresh();
    
        }
    
        private void initFresh() {
            xRecView.setLoadingListener(new XRecyclerView.LoadingListener() {
                @Override
                public void onRefresh() {
                    if (sjList != null) {
                        initDataSJ();
                        xRecAdapterSJ.notifyDataSetChanged();
                    }
                    xRecView.refreshComplete();
                    Toast.makeText(MainActivity.this, "刷新了数据", Toast.LENGTH_SHORT).show();
                }
    
                @Override
                public void onLoadMore() {
                    if (sjList != null) {
                        sjList.addAll(sjList.size(), sjList);
                        xRecAdapterSJ.notifyDataSetChanged();
                    }
                    xRecView.loadMoreComplete();
                    Toast.makeText(MainActivity.this, "加载了数据", Toast.LENGTH_SHORT).show();
                }
            });
        }
    
        public void qieHuan(View view) {
    
            Toast.makeText(MainActivity.this, "点击了切换视图按钮", Toast.LENGTH_SHORT).show();
            if (b == true) {
                //点击后想要变成什么要的布局样式就搞一个你的需求
                xRecView.setLayoutManager(new GridLayoutManager(MainActivity.this, 2));
                //给布尔值重新赋值
                b = false;
                //给点击按钮的图片重新赋值
                qhIv.setImageResource(R.mipmap.lv_icon);
            } else if (b == false) {
                xRecView.setLayoutManager(new LinearLayoutManager(MainActivity.this));
                //给布尔值重新赋值
                b = true;
                //给点击按钮的图片重新赋值
                qhIv.setImageResource(R.mipmap.grid_icon);
            }//
    
        }
    
        public void souSuoBut(View view) {
            srkStr = srkEdt.getText().toString();
            Log.e("++++++", "这是输入框的返回字符串内容：" + srkStr);
            if (srkStr.equals("")) {
       //
                Toast.makeText(MainActivity.this, "请输入内容", Toast.LENGTH_SHORT).show();
            } else if (srkStr.equals("sj")) {
                initDataSJ();
                Toast.makeText(MainActivity.this, "展示手机的数据", Toast.LENGTH_SHORT).show();
            } else if (srkStr.equals("bjb")) {
                initDataBJB();
                Toast.makeText(MainActivity.this, "展示笔记本的数据", Toast.LENGTH_SHORT).show();
            }
        }
    
    
    
    }

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 class BJBean {
    
        /**
         * msg : 查询成功
         * code : 0
         * data : [{

        public interface OnGetServerDateLisnter { 
            void getData(String string);
        }
    }

第二类是NetWorkUtils

public class NetWorkUtils { //判断网络是否连接 public static boolean isNetWorkAvailable(Context context) { //网络连接管理器 ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); //网络信息 NetworkInfo info = connectivityManager.getActiveNetworkInfo(); if (info != null) { return true; } return false; } }

第三个MyAPP类

public class MyApp extends Application { private static MyApp mInstance; @Override public void onCreate() { super.onCreate(); mInstance=this; ImageLoaderConfiguration defaultcof = ImageLoaderConfiguration.createDefault(getApplicationContext()); ImageLoader.getInstance().init(defaultcof); } public static MyApp getInstance(){ return mInstance; }; }

第四个GsonObjectCallback类

public abstract class GsonObjectCallback<T> implements Callback {
    
        private Handler handler = OkHttp3Utils.getInstance().getHandler();
    
        //主线程处理
        public abstract void onUi(T t);
    
        //主线程处理
        public abstract void onFailed(Call call, IOException e);
    
        //请求失败
        @Override
        public void onFailure(final Call call, final IOException e) {
            handler.post(new Runnable() {
                @Override
                public void run() {
                    onFailed(call, e);
                }
            });
        }
    
        //请求json 并直接返回泛型的对象 主线程处理
        @Override
        public void onResponse(Call call, Response response) throws IOException {
            String json = response.body().string();
            Class<T> cls = null;
    
            Class clz = this.getClass();
            ParameterizedType type = (ParameterizedType) clz.getGenericSuperclass();
            Type[] types = type.getActualTypeArguments();
            cls = (Class<T>) types[0];
            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<BJBean.DataBean> bjbList; private MainActivity mainActivity; public XRecAdapterBJB(List<BJBean.DataBean> 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<SJBean.DataBean> sjList;
        private MainActivity mainActivity;
    
        public XRecAdapterSJ(List<SJBean.DataBean> 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);
            }
        }
    
    
    }
