图如下：

记得要导okhttp的原生包即可；

导依赖：

    compile 'com.google.code.gson:gson:2.8.2'    compile 'com.squareup.okhttp3:okhttp:3.9.0'    compile 'com.github.liuguangqiang.SuperRecyclerView:super-recyclerview:0.1.2'    compile 'com.liaoinstan.springview:library:1.2.6'    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

代码如下：

首先是Mainactivity布局：

    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="60dp">        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:text="搜索商品"            android:textSize="20dp"/>        <ImageView            android:id="@+id/image"            android:layout_width="60dp"            android:layout_height="40dp"            android:layout_alignParentRight="true"            android:layout_centerVertical="true"            android:src="@drawable/san"/>    </RelativeLayout>    <TextView        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="#000000"/>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="60dp"        android:gravity="center"        android:orientation="horizontal">        <EditText            android:id="@+id/name"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="5"            android:hint="请输入关键字"/>        <Button            android:id="@+id/sousuo"            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="1"            android:text="搜索"/>    </LinearLayout>    <TextView        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="#000000"/>    <com.liaoinstan.springview.widget.SpringView        android:id="@+id/springview"        android:layout_width="match_parent"        android:layout_height="match_parent">        <android.support.v7.widget.RecyclerView            android:id="@+id/recyclerview"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:background="#ffffff"/>    </com.liaoinstan.springview.widget.SpringView>

在是适配器的两个布局：

 <ImageView        android:id="@+id/image"        android:layout_width="100dp"        android:layout_height="100dp"        android:src="@mipmap/ic_launcher"/>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical">        <TextView            android:id="@+id/title"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:text="ssdsdsddfffddffdfd"            android:textSize="20dp"/>        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:orientation="horizontal">            <TextView                android:id="@+id/price"                android:layout_width="0dp"                android:layout_height="wrap_content"                android:layout_weight="1"                android:text="原价：的颠三倒四"/>            <TextView                android:id="@+id/youhui"                android:layout_width="0dp"                android:layout_height="wrap_content"                android:layout_weight="1"                android:text="大的司法改革"                android:textColor="#ff0000"/>        </LinearLayout>    </LinearLayout>

//---------------------------------------------------------------------------------------------------------------------------------------------------------------------

 <ImageView        android:id="@+id/image1"        android:layout_width="100dp"        android:layout_height="100dp"        android:src="@mipmap/ic_launcher"/>    <TextView        android:id="@+id/title1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="ssdsdsddfffddffdfd"        android:textSize="20dp"/>    <TextView        android:id="@+id/price1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="原价：的颠三倒四"/>    <TextView        android:id="@+id/youhui1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="大的司法改革"        android:textColor="#ff0000"/>

MVP的model传给mymolder的参数：

public interface SouModel {    public void get(String name, String page, Callback callback);}

Mymodel

public class MySouModel implements SouModel {    @Override    public void get(String name, String page, Callback callback) {        HashMap<String, String> map = new HashMap<>();        map.put("keywords",name);        map.put("page",page);        OkHttp3Utils.doPost("http://120.27.23.105/product/searchProducts?source=android",map,callback);    }}

MVP的view：

public interface SouView {    public void success(Bean bean);    public void failuer(Exception e);}

MVP的persenter：

public class SouPersenter {    SouView view;    Context context;    private final MySouModel model;    public SouPersenter(SouView view, Context context) {        this.view = view;        this.context = context;        model = new MySouModel();    }    public void getData(String name,String page){        model.get(name, page, new OnUiCallback() {            @Override            public void onFailed(Call call, IOException e) {                if (view != null){                    view.failuer(e);                }            }            @Override            public void onSuccess(String result) {                Gson gson = new Gson();                Bean bean = gson.fromJson(result, Bean.class);                view.success(bean);            }        });    }    public void sasa(){        this.view = null;    }}

MainActivity页面：

public class MainActivity extends AppCompatActivity implements SouView {    @BindView(R.id.image)    ImageView image;    @BindView(R.id.name)    EditText name;    @BindView(R.id.sousuo)    Button sousuo;    @BindView(R.id.recyclerview)    RecyclerView recyclerview;    @BindView(R.id.springview)    SpringView springview;    SouPersenter persenter = new SouPersenter(this, this);    List<Bean.DataBean> list = new ArrayList<>();    private boolean flag = true;    private MyAdapter adapter;    private int page = 1;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        springview.setHeader(new DefaultHeader(this));        springview.setFooter(new DefaultFooter(this));        //设置SpringView的刷新监听事件        springview.setListener(new SpringView.OnFreshListener() {            @Override            public void onRefresh() {                springview.onFinishFreshAndLoad();                adapter.notifyDataSetChanged();            }            @Override            public void onLoadmore() {                persenter.getData(name.getText().toString(), page + "");                springview.onFinishFreshAndLoad();            }        });    }    @OnClick({R.id.image, R.id.sousuo})    public void onClick(View view) {        switch (view.getId()) {            case R.id.image:                if (flag == false) {                    flag = true;                    image.setImageResource(R.drawable.san);                    LinearLayoutManager manager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);                    recyclerview.setLayoutManager(manager);                    adapter = new MyAdapter(this, list, flag);                    recyclerview.setAdapter(adapter);                    setadapter();                } else if (flag == true) {                    flag = false;                    image.setImageResource(R.drawable.si);                    GridLayoutManager manager = new GridLayoutManager(this, 2);                    recyclerview.setLayoutManager(manager);                    adapter = new MyAdapter(this, list, flag);                    recyclerview.setAdapter(adapter);                    setadapter();                }                break;            case R.id.sousuo:                if (flag == true) {                    LinearLayoutManager manager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);                    recyclerview.setLayoutManager(manager);                    adapter = new MyAdapter(this, list, flag);                    recyclerview.setAdapter(adapter);                } else if (flag == false) {                    GridLayoutManager manager = new GridLayoutManager(this, 2);                    recyclerview.setLayoutManager(manager);                    adapter = new MyAdapter(this, list, flag);                    recyclerview.setAdapter(adapter);                }                persenter.getData(name.getText().toString(), "1");                break;        }    }    private void setadapter() {        if (adapter != null) {            adapter = new MyAdapter(this, list, flag);            recyclerview.setAdapter(adapter);        } else {            adapter.notifyDataSetChanged();        }    }    @Override    public void success(Bean bean) {//        for (int i = 0; i <bean.getData().size() ; i++) {//            list.add(bean.getData().get(i));//        }        list.addAll(bean.getData());        adapter = new MyAdapter(this, list, flag);        recyclerview.setAdapter(adapter);    }    @Override    public void failuer(Exception e) {        Toast.makeText(MainActivity.this, "错误", Toast.LENGTH_SHORT).show();    }    @Override    protected void onDestroy() {        super.onDestroy();        persenter.sasa();    }}

adapter适配器页面：

public class MyAdapter extends RecyclerView.Adapter {    Context context;    List<Bean.DataBean> list;    boolean flag;    public MyAdapter(Context context, List<Bean.DataBean> list, boolean flag) {        this.flag = flag;        this.context = context;        this.list = list;        ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(context));    }    @Override    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        if (flag == true) {            View view = LayoutInflater.from(context).inflate(R.layout.item_adapter, null);            return new MyViewHolder(view);        } else if (flag == false) {            View view = LayoutInflater.from(context).inflate(R.layout.item_si, null);            return new ViewHolder01(view);        }        return new MyViewHolder(parent);    }    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {        if (holder instanceof MyViewHolder) {            MyViewHolder holder1 = (MyViewHolder) holder;            holder1.title.setText(list.get(position).getTitle());            holder1.youhui.setText("优惠价:" + list.get(position).getPrice());            holder1.price.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG); //中间横线（删除线）            holder1.price.setText("原价：￥" + list.get(position).getBargainPrice());            String[] split = list.get(position).getImages().split("\\|");            ImageLoader.getInstance().displayImage(split[0], holder1.image);        }else if (holder instanceof ViewHolder01) {            ViewHolder01 holder1 = (ViewHolder01) holder;            holder1.title1.setText(list.get(position).getTitle());            holder1.youhui1.setText("优惠价:" + list.get(position).getPrice());            holder1.price1.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG); //中间横线（删除线）            holder1.price1.setText("原价：￥" + list.get(position).getBargainPrice());            String[] split = list.get(position).getImages().split("\\|");            ImageLoader.getInstance().displayImage(split[0], holder1.image1);        }    }    @Override    public int getItemCount() {        return list == null ? 0 : list.size();    }    public class MyViewHolder extends RecyclerView.ViewHolder {        @BindView(R.id.image)        ImageView image;        @BindView(R.id.title)        TextView title;        @BindView(R.id.price)        TextView price;        @BindView(R.id.youhui)        TextView youhui;        public MyViewHolder(View itemView) {            super(itemView);            ButterKnife.bind(this, itemView);        }    }    static class ViewHolder01 extends RecyclerView.ViewHolder {        @BindView(R.id.image1)        ImageView image1;        @BindView(R.id.title1)        TextView title1;        @BindView(R.id.price1)        TextView price1;        @BindView(R.id.youhui1)        TextView youhui1;        ViewHolder01(View itemView) {            super(itemView);            ButterKnife.bind(this, itemView);        }    }}
