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() {
                @Override
                public void onCompleted() {

                }

                @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

            this.name = name;
        }

        public int getPcid() {
            return pcid;
        }

        public void setPcid(int pcid) {
            this.pcid = pcid;
        }

        public int getPscid() {
            return pscid;
        }

        public void setPscid(int pscid) {
            this.pscid = pscid;
        }
    }
}

}

P层
present的接口
public interface IuserPresenter {
void getPresenter();
}
present的类
public class Mypresenter implements IuserPresenter,Wangluo{
ShowModel showModel;
IuserView iuserView;
//
public Mypresenter(IuserView iuserView) {
this.showModel = new GetModel();
this.iuserView = iuserView;
}

@Override
public void getPresenter() {
    showModel.showmodel(this);
}

@Override
public void getWl(HomeBean homeBean) {
    iuserView.getView(homeBean);
}

}

V层
public interface IuserView {
void getView(HomeBean homeBean);
}

最后在HomeFragment实现view层的接口

public class HomeFragment extends Fragment implements IuserView {

private Banner banner;
private List imageUrl;
private List bannerTitle;

private List mDatas = new ArrayList<>();
private String url;
private List lists;
private List data;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_home, container, false);
      banner = view.findViewById(R.id.banner);

    Mypresenter mypresenter = new Mypresenter(this);
    mypresenter.getPresenter();

    return view ;
}

@Override
public void getView(HomeBean homeBean) {
    data = homeBean.getData();
    lists = new ArrayList<>();
    for(int i = 0; i< data.size(); i++){
        url = data.get(i).getIcon();
        lists.add(url);
    }
    banner.setImageLoader(new GlideImageLoader());
    banner.setImages(lists);
    banner.start();
}

private void initData() {
    //图片地址
    imageUrl = new ArrayList<>();
    imageUrl.add("http://img05.tooopen.com/images/20140604/sy_62331342149.jpg");
    imageUrl.add("http://pic33.nipic.com/20130916/3420027_192919547000_2.jpg");
    imageUrl.add("http://img.taopic.com/uploads/allimg/121017/234940-12101FR22825.jpg");
   /* //Title名称
    bannerTitle = new ArrayList<>();
    bannerTitle.add("一");
    bannerTitle.add("二");
    bannerTitle.add("三");*/
}

private void initView() {
    banner.setImageLoader(new GlideImageLoader());
    banner.setImages(imageUrl);
    banner.setDelayTime(3000);
    banner.start();
}

}
