定義一個介面HomPageContract
public interface HomPageContract { interface View extends BaseContract.BaseView{ void getAdSuccess(AdBean adBean); void getCatagorySuccess(CatagoryBean catagoryBean); } interface Presenter extends BaseContract.BasePresenter<View>{ voidgetAd(); void getCatagory(); } }
寫一個HomePagePresenter類
public class HomePagePresenter extends BasePresenter<HomPageContract.View> implements HomPageContract.Presenter { private AdApi adApi; private CatagoryApi catagoryApi; @Inject public HomePagePresenter(AdApi adApi, CatagoryApi catagoryApi) { this.adApi = adApi; this.catagoryApi = catagoryApi; } @Override public void getAd() { adApi.getAd() .observeOn(AndroidSchedulers.mainThread()) .subscribeOn(Schedulers.io()) .subscribe(new Observer<AdBean>() { @Overridepublic void onSubscribe(Disposable d) { } @Override public void onNext(AdBean adBean) { mView.getAdSuccess(adBean); } @Override public void onError(Throwable e) { } @Override public void onComplete() { } }); } @Override public void getCatagory() { catagoryApi.getCatagory() .observeOn(AndroidSchedulers.mainThread()) .subscribeOn(Schedulers.io()) .subscribe(new Observer<CatagoryBean>() { @Override public void onSubscribe(Disposable d) { } @Override public void onNext(CatagoryBean catagoryBean) { mView.getCatagorySuccess(catagoryBean); } @Override public void onError(Throwable e) { } @Override public void onComplete() { } }); } }
