易学MVP 个络加载数据+XRecyclerView+Retrofit

第一步:配置权限和导包:

<uses-permission android:name="android.permission.INTERNET"></uses-permission><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.VIBRATE" />

compile 'com.jcodecraeer:xrecyclerview:1.3.2'compile 'com.squareup.retrofit2:retrofit:2.0.1'compile 'com.squareup.retrofit2:converter-gson:2.0.1'compile 'com.squareup.retrofit2:adapter-rxjava:2.0.1'compile 'io.reactivex:rxandroid:1.1.0'compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'compile 'com.facebook.fresco:fresco:0.9.0+'compile 'com.android.support:mediarouter-v7:25.0.0'compile 'com.android.support:appcompat-v7:25.0.0'compile 'com.android.support:recyclerview-v7:25.0.0'

第二步:创建三个包,创建两个接口,分别是model,view俩个接口:

public interface Iview {    void  getdata(List<Mysupercalss.DataBean> data);}

public interface Imodel {    void login(String mm);}

第三步:model实现接口:

package model;import java.util.List;import bean.API;import bean.Iservers;import bean.Mysupercalss;import retrofit2.Retrofit;import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;import retrofit2.converter.gson.GsonConverterFactory;import rx.Observable;import rx.Observer;import rx.android.schedulers.AndroidSchedulers;import rx.schedulers.Schedulers;/** * Created by Administrator on 2017/11/5 0005. */public class Mymodel implements Imodel {    private OnFinishLisenter lisenter;    //定义接口    public interface OnFinishLisenter{        void onFinish(List<Mysupercalss.DataBean> userBean);    }    public void setOnFinishLisenter(OnFinishLisenter lisenter){        this.lisenter = lisenter;    }    @Override    public void login(String mm) {        Retrofit retrofit = new Retrofit.Builder().baseUrl(API.MYAPI).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).build();        Iservers apiser = retrofit.create(Iservers.class);        Observable<Mysupercalss> gethom = apiser.getdata();        gethom.subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(new Observer<Mysupercalss>() {                    @Override                    public void onCompleted() {                    }                    @Override                    public void onError(Throwable e) {                    }                    @Override                    public void onNext(Mysupercalss mysup) {                        lisenter.onFinish(mysup.getData());                    }                });    }}

第四步:Persenter层:

package presenter;import java.util.List;import bean.Mysupercalss;import model.Mymodel;import view.Iview;/** * Created by Administrator on 2017/11/5 0005. */public class Mypre implements Mymodel.OnFinishLisenter {    private Iview iview;    private  Mymodel mymodel;    public Mypre(Iview iview) {        this.iview = iview;        this.mymodel = new Mymodel();    }    public   void  setadapter(String path){        mymodel.setOnFinishLisenter(this);        mymodel.login(path);    }    @Override    public void onFinish(List<Mysupercalss.DataBean> userBean) {        iview.getdata(userBean);    }}

需要注意的是这里使用了接口回调,再调用时需要注意顺序的问题

第五步:MainActivity:

package com.example.mvp_retrofit;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.LinearLayoutManager;import com.jcodecraeer.xrecyclerview.XRecyclerView;import java.util.List;import bean.API;import bean.MyAdapter;import bean.Mysupercalss;import presenter.Mypre;import view.Iview;public class MainActivity extends AppCompatActivity implements Iview{    XRecyclerView xrecyclerview;    List<Mysupercalss.DataBean> list;    MyAdapter adapter;    Mypre mypre;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        xrecyclerview = (XRecyclerView)findViewById(R.id.xrecyclerview);        LinearLayoutManager layoutManager = new LinearLayoutManager(this);/*        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);*/        xrecyclerview.setLayoutManager(layoutManager);        mypre=new Mypre(this);        mypre.setadapter(API.MYAPI);    }    @Override    public void getdata(final List<Mysupercalss.DataBean> data) {        adapter = new MyAdapter(MainActivity.this, data);        xrecyclerview.setAdapter(adapter);            xrecyclerview.setLoadingListener(new XRecyclerView.LoadingListener() {                @Override                public void onRefresh() {                    list=data;                    adapter.notifyDataSetChanged();                    xrecyclerview.refreshComplete();                }                @Override                public void onLoadMore() {                    list.addAll(data);                    adapter.notifyDataSetChanged();                    xrecyclerview.loadMoreComplete();                }            });    }}

还有url和适配器我就不贴了,可以根据自己的json串来做响应的改变.
