先看效果

首先要添加依赖

    compile 'com.github.bumptech.glide:glide:3.7.0'    compile 'com.squareup.okhttp3:okhttp:3.9.0'    compile 'com.google.code.gson:gson:2.6.1'    compile 'com.jcodecraeer:xrecyclerview:1.3.2'

网络权限也不能忘

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

先看看MVP的分包

先看Model层的IRecyModel
import okhttp3.Callback;/** * Created by BAIPEI on 2017/12/7. */public interface IRecyModel {    void recy(Callback callback);}
再看IRecyModel接口的实现类
import bwie.com.mvp.utils.OkHttpUtils;import okhttp3.Callback;/** * Created by BAIPEI on 2017/12/7. */public class RecyModel implements IRecyModel {    @Override    public void recy(Callback callback) {        OkHttpUtils.getInstance().doGet("http://m.yunifang.com/yunifang/mobile/home", callback);    }}
接下来我们来看view层IRecyView
import bwie.com.mvp.bean.InfoDatas;/** * Created by BAIPEI on 2017/12/7. */public interface IRecyView {    void showRecy(InfoDatas infoDatas);}
下面就到了Presenter层
import android.util.Log;import com.google.gson.Gson;import java.io.IOException;import bwie.com.mvp.bean.InfoDatas;import bwie.com.mvp.model.IRecyModel;import bwie.com.mvp.model.RecyModel;import bwie.com.mvp.utils.OnUiCallback;import bwie.com.mvp.view.IRecyView;import okhttp3.Call;/** * Created by BAIPEI on 2017/12/7. */public class RecyPresenter {    private IRecyView view;    private IRecyModel model;    public RecyPresenter(IRecyView view) {        this.view = view;        model = new RecyModel();    }    public void showRecy(){        model.recy(new OnUiCallback() {            private InfoDatas infoDatas;            @Override            public void onFailed(Call call, IOException e) {            }            @Override            public void onSuccess(String result) throws IOException {                Log.i("ss",result);                Gson gson = new Gson();                infoDatas = gson.fromJson(result, InfoDatas.class);                view.showRecy(infoDatas);            }        });    }    //解绑    public void onDestory(){        view = null;    }}
OkHttpUtils
切记这里的Handler 导的是import android.os.Handler;这个包
import android.os.Handler;import android.os.Looper;import okhttp3.Call;import okhttp3.Callback;import okhttp3.OkHttpClient;import okhttp3.Request;/** * Created by BAIPEI on 2017/12/7. */public class OkHttpUtils {    private Handler handler = new Handler(Looper.getMainLooper());    public Handler getHandler(){        return handler;    }    //单例    private static OkHttpUtils okHttpUtils = new OkHttpUtils();    private OkHttpUtils(){};    public static OkHttpUtils getInstance(){        return okHttpUtils;    }    private OkHttpClient client;    private void initOkHttpClient(){        if(client == null){            client = new OkHttpClient.Builder().build();        }    }    //公用的get请求方法  完成的功能不确定    public void doGet(String url, Callback callback){        initOkHttpClient();        Request request = new Request.Builder().addHeader("User-Agent","").url(url).build();        Call call = client.newCall(request);        call.enqueue(callback);    }}
OnUiCallback
import android.os.Handler;import java.io.IOException;import okhttp3.Call;import okhttp3.Callback;import okhttp3.Response;/** * Created by BAIPEI on 2017/12/7. */public abstract class OnUiCallback implements Callback {    private Handler handler = OkHttpUtils.getInstance().getHandler();    public abstract void onFailed(Call call, IOException e);    public abstract void onSuccess(String result) throws IOException;    @Override    public void onFailure(final Call call, final IOException e) {        //该方式  存在问题  网络请求也跑到了主线程   待解决        //该方法就是把  线程post到handler所在的线程        handler.post(new Runnable() {            @Override            public void run() {                onFailed(call, e);            }        });    }    @Override    public void onResponse(final Call call, final Response response) throws IOException {        final String result = response.body().string();        //该方式  存在问题  网络请求也跑到了主线程   待解决        handler.post(new Runnable() {            @Override            public void run() {                try {                    onSuccess(result);                } catch (IOException e) {                    e.printStackTrace();                }            }        });    }}
到了RecyActivity
import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.support.v7.widget.LinearLayoutManager;import com.jcodecraeer.xrecyclerview.XRecyclerView;import bwie.com.mvp.adapder.MyRecyAdapter;import bwie.com.mvp.bean.InfoDatas;import bwie.com.mvp.presenter.RecyPresenter;import bwie.com.mvp.view.IRecyView;public class RecyActivity extends AppCompatActivity implements IRecyView {    private XRecyclerView xrv;    private RecyPresenter presenter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_recy);        initView();        presenter = new RecyPresenter(this);        presenter.showRecy();    }    private void initView() {        xrv = (XRecyclerView) findViewById(R.id.xrv);        LinearLayoutManager manager = new LinearLayoutManager(this);        manager.setOrientation(LinearLayoutManager.VERTICAL);        xrv.setLayoutManager(manager);        //下面是加载更多的方法    }    @Override    public void showRecy(InfoDatas infoDatas) {        MyRecyAdapter myRecyAdapter = new MyRecyAdapter(this, infoDatas);        xrv.setAdapter(myRecyAdapter);    }}

下面是适配器Adapter
import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import com.bumptech.glide.Glide;import bwie.com.mvp.R;import bwie.com.mvp.bean.InfoDatas;/** * Created by BAIPEI on 2017/12/7. */public class MyRecyAdapter extends RecyclerView.Adapter<MyRecyAdapter.MyViewHolder> {    private Context context;    private InfoDatas infoDatas;    public MyRecyAdapter(Context context, InfoDatas infoDatas) {        this.context = context;        this.infoDatas = infoDatas;    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(context).inflate(R.layout.recy_item, parent, false);        MyViewHolder holder = new MyViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(MyViewHolder holder, int position) {        Glide.with(context).load(infoDatas.data.defaultGoodsList.get(position).goods_img).into(holder.iv_item);        holder.tv_item.setText(infoDatas.data.defaultGoodsList.get(position).goods_name);    }    @Override    public int getItemCount() {        return infoDatas.data.defaultGoodsList.size();    }    static class MyViewHolder extends RecyclerView.ViewHolder{        ImageView iv_item;        TextView tv_item;        public MyViewHolder(View itemView) {            super(itemView);            iv_item = itemView.findViewById(R.id.iv_item);            tv_item = itemView.findViewById(R.id.tv_item);        }    }}
下面是bean类
import java.util.List;/** * Created by BAIPEI on 2017/12/7. */public class InfoDatas {    public int code;    public String msg;    public DataEntity data;    public static class DataEntity {        public ActivityInfoEntity activityInfo;        public boolean creditRecived;        public GoodsSpreeActivityEntity goodsSpreeActivity;        public SecondAdEntity secondAd;        public List<SubjectsEntity> subjects;        public List<Ad1Entity> ad1;        public List<Ad5Entity> ad5;        public List<Ad8Entity> ad8;        public List<DefaultGoodsListEntity> defaultGoodsList;        public static class ActivityInfoEntity {            public String activityAreaDisplay;            public List<ActivityInfoListEntity> activityInfoList;            public static class ActivityInfoListEntity {                public String id;                public String activityImg;                public String activityType;                public String activityData;                public String activityDataDetail;                public String activityAreaDisplay;                public String countDownEnable;                public String remark;                public int sort;            }        }        public static class GoodsSpreeActivityEntity {            public String id;            public String name;            public String startDate;            public String endDate;            public String status;            public String startSeconds;            public String endSeconds;            public String isChecked;            public List<GoodsListEntity> goodsList;            public static class GoodsListEntity {                public String id;                public String goodsSpreeId;                public String goodsId;                public String goodsName;                public String goodsImg;                public double marketPrice;                public double activityPrice;                public int salesRatio;                public int stockNumber;                public int releaseNumber;            }        }        public static class SecondAdEntity {            public String id;            public String image;            public int ad_type;            public int sort;            public int position;            public int enabled;            public String ad_type_dynamic;            public String ad_type_dynamic_data;            public String ad_type_dynamic_detail;            public GoodsEntity goods;            public static class GoodsEntity {                public int collect_count;                public boolean reservable;                public int restriction;                public int restrict_purchase_num;                public boolean is_coupon_allowed;                public int allocated_stock;                public int is_gift;            }        }        public static class SubjectsEntity {            public String id;

           public String state;            public int sort;            public String descImage;            public String template;            public String url;            public String wapUrl;            public List<GoodsListEntity> goodsList;            public List<String> goodsIdsList;            public List<GoodsRelationListEntity> goodsRelationList;            public static class GoodsListEntity {                public String id;                public String goods_name;                public double shop_price;                public double market_price;                public String goods_img;                public boolean reservable;                public String efficacy;                public int stock_number;                public int restrict_purchase_num;                public String goodsName;                public String goodsImage;                public String description;            }            public static class GoodsRelationListEntity {                public String id;                public String subject_id;                public String goods_id;                public String goodsName;                public String goodsImage;                public String description;            }        }        public static class Ad1Entity {            public String id;            public String createtime;            public String lastupdatetime;            public String image;            public int ad_type;            public int sort;            public int position;            public int enabled;            public String createuser;            public String lastupdateuser;            public String ad_type_dynamic;            public String ad_type_dynamic_data;            public String ad_type_dynamic_detail;            public String show_channel;            public String title;            public String channelType;        }        public static class Ad5Entity {            public String id;            public String image;            public int ad_type;            public int sort;            public int position;            public int enabled;            public String ad_type_dynamic;            public String ad_type_dynamic_data;            public String ad_type_dynamic_detail;

           public int sort;            public int position;            public int enabled;            public String description;            public String ad_type_dynamic;            public String ad_type_dynamic_data;            public String ad_type_dynamic_detail;            public String show_channel;            public String title;            public GoodsEntity goods;            public static class GoodsEntity {                public int collect_count;                public boolean reservable;                public int restriction;                public int restrict_purchase_num;                public boolean is_coupon_allowed;                public int allocated_stock;                public int is_gift;            }        }        public static class DefaultGoodsListEntity {            public String id;            public String goods_name;            public double shop_price;            public double market_price;            public String goods_img;            public boolean reservable;            public String efficacy;            public int stock_number;            public int restrict_purchase_num;        }    }}
逻辑代码就这么多,下面是布局代码
activity_recy
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="bwie.com.mvp.RecyActivity">    <com.jcodecraeer.xrecyclerview.XRecyclerView        android:id="@+id/xrv"        android:layout_width="match_parent"        android:layout_height="match_parent"></com.jcodecraeer.xrecyclerview.XRecyclerView></RelativeLayout>
recy_item
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="50dp"    android:orientation="horizontal">    <ImageView        android:id="@+id/iv_item"        android:layout_width="50dp"        android:layout_height="match_parent" />    <TextView        android:id="@+id/tv_item"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:text="我是文本"        android:textSize="20sp"/></LinearLayout>
一个用MVP框架做的网络请求就出来了
