Mvp应用方法

创建包

 api 
 bean 
 callBack 
 model 
 presenter
 view
    

api里面写

    OneApiServer
        String baseUrl="http://gank.io/api/data/";
    @GET("%E7%A6%8F%E5%88%A9/20/1")
    Observable<DayEightBean>getData();

bean写bean包

    callback(interface)里面写
    //成功
        void onSuccess(List<Bean> bean);
    //失败
    void onFail(String fail);
        
    ！！model里写
    ··Model
    public interface Model {
    void getData(OneCallBack oneCallBack);
    }

ImpModel

    public class ImpNewsMedel extends Activity implements NewsModel {
    private int page=0;
    public static int clear(int a){
        return a=0;
    }
    public void onResume() {
        super.onResume();
    }

    @Override
    public void getNewlsit(final FlCallback flCallback) {
        Retrofit retrofit = new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .baseUrl(NewsServer.baseUrl)
                .build();

        NewsServer newsServer = retrofit.create(NewsServer.class);
        Observable<NewsBean> observable = newsServer.getUrl("20/"+page+++"");
        observable.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<NewsBean>() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }

                    @Override
                    public void onNext(NewsBean newsBean) {
                    flCallback.onSuccess(newsBean);
                    }

                    @Override
                    public void onError(Throwable e) {
                    flCallback.onFail("net error:"+e.getMessage());
                    }

                    @Override
                    public void onComplete() {

                    }
                });
    }

}

presenter里写
··Presenter

    public interface NewsPresenter {
    void getData();
}

ImpPresenter

public class Imppresenter implements Adpresenter, Adcallback {
    private Admodel admodel;
    private Adview adview;

    public Imppresenter(Impmodel impmodel, Adview adview) {
        this.admodel = impmodel;
        this.adview = adview;
    }

    @Override
    public void getData() {
        if (admodel!=null){
            admodel.getData(this);
        }

    }

    @Override
    public void onSuccess(AdBean adBean) {
        if (adview!=null){
            adview.onSuccess(adBean);
        }
    }

    @Override
    public void onFail(String fail) {
        if (adview!=null){
            adview.onFail(fail);
        }
    }

View

    public interface NewsView {
    void onSuccess(NewsBean newsBean);
    void onFail(String error);
}
