在activity_main.xml中的布局：


<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="com.example.zhokaosansousuo.MainActivity"android:orientation="vertical"><LinearLayout
        android:layout_width="match_parent"android:layout_height="40dp"android:orientation="horizontal"><TextView
            android:layout_width="match_parent"android:layout_height="match_parent"android:layout_weight="1"android:gravity="center"android:text="搜索商品"android:textSize="22sp" /><ImageView
            android:id="@+id/qieHuanIv"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_weight="9"android:src="@mipmap/lv_icon"android:onClick="qieHuan"android:padding="10dp" /></LinearLayout><LinearLayout

        android:id="@+id/xRecView"android:layout_width="wrap_content"android:layout_height="wrap_content"></com.jcodecraeer.xrecyclerview.XRecyclerView></LinearLayout>

在创建一个Xrecview.xml布局：（适配器的item布局）


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><ImageView
        android:id="@+id/xRecView_itemsj_iv"android:layout_width="100dp"android:layout_height="100dp"android:scaleType="fitXY"android:src="@mipmap/ic_launcher"/><LinearLayout
        android:layout_width="match_parent"android:layout_height="100dp"android:orientation="vertical"android:gravity="center_vertical"><TextView
            android:id="@+id/xRecView_itemsj_titel"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="标题"android:singleLine="true"android:textSize="22sp"/><TextView
            android:id="@+id/xRecView_itemsj_yuanJia"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="10000"/><TextView
            android:id="@+id/xRecView_itemsj_xianJia"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="50"android:textColor="@color/colorAccent"/></LinearLayout></LinearLayout>

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;@Overrideprotected 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>() {@Overridepublic void onUi(BJBean bjbBean) {bjbList = bjbBean.getData();xRecView.setLayoutManager(new LinearLayoutManager(MainActivity.this));xRecAdapterBJB = new XRecAdapterBJB(bjbList, MainActivity.this);xRecView.setAdapter(xRecAdapterBJB);}@Overridepublic 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>() {@Overridepublic void onUi(SJBean sjBean) {sjList = sjBean.getData();xRecAdapterSJ = new XRecAdapterSJ(sjList, MainActivity.this);xRecView.setLayoutManager(new LinearLayoutManager(MainActivity.this));xRecView.setAdapter(xRecAdapterSJ);}@Overridepublic 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() {@Overridepublic void onRefresh() {if (sjList != null) {initDataSJ();xRecAdapterSJ.notifyDataSetChanged();}xRecView.refreshComplete();Toast.makeText(MainActivity.this, "刷新了数据", Toast.LENGTH_SHORT).show();}@Overridepublic 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 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;@Overridepublic 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@Overridepublic void onFailure(final Call call, final IOException e) {handler.post(new Runnable() {@Overridepublic void run() {onFailed(call, e);}});}//请求json 并直接返回泛型的对象 主线程处理@Overridepublic 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() {@Overridepublic 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;}@Overridepublic RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = View.inflate(mainActivity, R.layout.xrecview, null);XRecViewHolder xRecViewHolder = new XRecViewHolder(view);return xRecViewHolder;}@Overridepublic 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);}@Overridepublic 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;}@Overridepublic RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = View.inflate(mainActivity,R.layout.xrecview,null);XRecViewHolder xRecViewHolder = new XRecViewHolder(view);return xRecViewHolder;}@Overridepublic 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);}@Overridepublic 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);}}}
