MVP+Retrofit2+RxJava京东的分类页面

网上有许许多多这种例子 这是根据我自己的理解集成的一个MVP

首先导入他的依赖

compile ‘com.youth.banner:banner:1.4.9’

compile ‘com.jakewharton:butterknife:8.4.0’

annotationProcessor ‘com.jakewharton:butterknife-compiler:8.4.0’

compile 'io.reactivex:rxandroid:1.1.0'
compile 'io.reactivex:rxjava:1.1.0'

compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.facebook.fresco:fresco:0.11.0'
compile 'io.reactivex:rxandroid:1.0.1'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'

compile 'org.greenrobot:eventbus:3.1.1'

先加入网络权限

*主页面的视图左边ListView 右边ExpandableListView*

从Api开始说起

APi类

public class Api {

//首页网址

public static final String HomeUrl =”https://www.zhaoapi.cn/”;

}

这是进行Rxjava的接口

public interface Apiservier {

@GET(“ad/getAd”)

Observable getUser();

**

然后就是M层 model层的接口

**

public interface ShowModel {

void showmodel(Wangluo wangluo);

}

model层的类

public class GetModel implements ShowModel {

@Override
public void showmodel(final Wangluo wangluo) {
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//新的配置
.baseUrl(Api.HomeUrl)
.build();
Apiservier apiSyserver = retrofit.create(Apiservier.class);
apiSyserver.getUser()
.subscribeOn(Schedulers.io())
//.observeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())//最后在主线程中执行
.subscribe(new Subscriber<HomeBean>() {
@Override
public void onComplet
4000
ed() {

}

@Override
public void onError(Throwable e) {

}

@Override
public void onNext(HomeBean homeBean) {
if(wangluo!=null){
wangluo.getWl(homeBean);
}
}
});

}

}

/判断网络连接成功的类

public interface Wangluo {

void getWl(HomeBean homeBean);

}

这是bean类

public class HomeBean {

private String msg;

private String code;

private TuijianBean tuijian;

private MiaoshaBean miaosha;

private List data;

public String getMsg() {
