MODEL包里

IMODEL

public interface IModel {
    void getJson(String url);
}

USERMODEL

public class UserModel implements IModel {


    ArrayList<HomeBean.NewslistBean> list;

    private OnFinish onFinish;

    public interface OnFinish{
        void OnFinishListener(ArrayList<HomeBean.NewslistBean> list);
    }

    public void setOnFinish(OnFinish finish){
        this.onFinish=finish;
    }



    @Override
    public void getJson(String url) {
        list = new ArrayList<>();
        Retrofit retrofit = new Retrofit.Builder().baseUrl(url).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).build();

        ApiService apiService = retrofit.create(ApiService.class);
        final Observable<HomeBean> home = apiService.getHome();
        home.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<HomeBean>() {
                    @Override
                    public void onCompleted() {

                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onNext(HomeBean homeBean) {
                        list = (ArrayList<HomeBean.NewslistBean>) homeBean.getNewslist();

                        onFinish.OnFinishListener(list);

                    }
                });

    }
}

IVIEW

public interface IView {
    void getUser(ArrayList<HomeBean.NewslistBean> list);
}

UPresenter

public class UserPresenter implements UserModel.OnFinish {
    private final IView userView;
    private final UserModel userModel;

    public UserPresenter(IView userView) {
        this.userView = userView;
        this.userModel = new UserModel();
        userModel.setOnFinish(this);
    }

    public void setNews(String url){
        userModel.getJson(url);
    }

    @Override
    public void OnFinishListener(ArrayList<HomeBean.NewslistBean> list) {
        userView.getUser(list);
    }
}

Main里面

implements IView

UserPresenter userPresenter;

userPresenter = new UserPresenter(this);
userPresenter.setNews(API.URLONE);

@Override
public void getUser(ArrayList<HomeBean.NewslistBean> list) {
    adapter = new MyRecyclerAdapter(list,getActivity());
    recycler.setAdapter(adapter);
}

APIService

public interface ApiService {
    @GET("xbsjxw/page_1.json")
    Observable<XwbjBean> getNews();

    @GET("tiyu/?key=691dce141baf9b719db22f6382ba5639&num=10")
    Observable<HomeBean> getHome();

}

API

public class API {
    public static final String URL="http://mnews.gw.com.cn/wap/data/news/";
    public static final String URLONE = "http://api.tianapi.com/";
}

Fresco

布局

<com.facebook.drawee.view.SimpleDraweeView
    android:id="@+id/recycler_head"
    android:layout_width="90dp"
    android:layout_height="90dp"
    android:layout_marginTop="15dp"
    fresco:actualImageScaleType="centerCrop"
    fresco:roundAsCircle="true"
    fresco:placeholderImage="@drawable/icon_placeholder"
    fresco:placeholderImageScaleType="fitCenter"
    fresco:roundingBorderColor="#f8bcf3"
    fresco:roundingBorderWidth="5dp"
    android:layout_alignParentTop="true"
    android:layout_toRightOf="@+id/id_num"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

使用

SimpleDraweeView head;

head = (SimpleDraweeView) itemView.findViewById(R.id.recycler_head);

Uri imageuri = Uri.parse(list.get(position).getPicUrl());
((MyViewHolder)holder).head.setImageURI(imageuri);
