MVP-Dagger2-Rxjava2-Retrofit整合

最近刚学习了MVP-Dagger2-Rxjava2-Retrofit

将MVP-Dagger2-Rxjava2-Retrofit做了一个简单的整合

贴出部分代码

源码下载地址在最下方

添加依赖：

    //retrofit

    compile 'com.squareup.retrofit2:retrofit:2.3.0'
    compile 'com.squareup.retrofit2:converter-gson:2.3.0'
    compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'     // 用于rxjava和retrofit 
    //okhttp
    compile 'com.squareup.okhttp3:okhttp:3.8.0'
    compile 'com.squareup.okhttp3:logging-interceptor:3.8.0'  //logging拦截器
    //dagger
    apt 'com.google.dagger:dagger-compiler:2.0.2'
    compile 'com.google.dagger:dagger:2.0.2'
    provided 'org.glassfish:javax.annotation:10.0-b28'
    //rxjava
    compile 'io.reactivex.rxjava2:rxjava:2.1.0'
    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'

 apply plugin: 'com.neenbedankt.android-apt'   //app model中添加

 dependencies {

        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'     //app build中添加

}

    
MVP的model部分，用来做数据处理
public class HomeModel {
    ApiService mApiService;
    public HomeModel(ApiService apiService) {
        mApiService = apiService;
    }
    public Observable<ResponseBody> getData() {
        Observable<ResponseBody> data = mApiService.getBannerData();
        return data;
    }

}

MVP的presenter部分，作为model和View的交互
public class HomePresenter extends BasePresenter<HomeModel, BaseView> {
    public HomePresenter(HomeModel model, BaseView view) {
        super(model, view);
    }
    @Override
    public void requestData() {
        mModel.getData()
                .subscribeOn(Schedulers.io())
                .subscribeOn(Schedulers.newThread())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<ResponseBody>() {
                    Disposable mDisposable;
                    @Override
                    public void onSubscribe(@NonNull Disposable d) {
                        mDisposable = d;
                    }
                   @Override
                    public void onNext(@NonNull ResponseBody responseBody) {
                        mView.showloading();
                        if (responseBody != null) {
                            mView.showResult(responseBody.toString());
                        } else {
                            mView.showNoData();
                        }
                        mView.showDismiss();
                    }
                    @Override
                    public void onError(@NonNull Throwable e) {
                        mView.showDismiss();
                        mView.showError(e.getMessage().toString());
                    }
                    @Override
                    public void onComplete() {
                        mView.showDismiss();
                        mDisposable.dispose();
                    }
                });
    }

}

Dagger module 提供方法
@Module
public class HomeModule {
    private BaseView mView;
    public HomeModule(BaseView view) {
        mView = view;
    }
    @Provides
    @UIScope
    public BaseView provideView() {
        return mView;
    }
    @Provides
    @UIScope
    public HomeModel provideHomeModel(ApiService apiService) {
        return new HomeModel(apiService);
    }
    @Provides
    @UIScope
    public HomePresenter provideHomePresenter(HomeModel model, BaseView view) {
        return new HomePresenter(model, view);
    }
    @Provides
    @UIScope
    public ProgressDialog provideProgressDialog(BaseView view) {
        return new ProgressDialog((Context) view);
    }

}

Dagger中Component关联module

@Singleton
@Component(modules = {AppModule.class, HttpModule.class})
public interface AppComponent {
    ApiService getApi();
}

自定义一个Application用于dagger的封装
public class MyApplication extends Application {
    private AppComponent mAppComponent;
    public static MyApplication get(Context context) {
        return (MyApplication) context.getApplicationContext();
    }
    public AppComponent getAppComponent() {
        return mAppComponent;
    }

最后mainActivity中

public class MainActivity extends AppCompatActivity implements BaseView {

    @Override
    public void onCreate() {
        super.onCreate();
        mAppComponent = DaggerAppComponent.builder().appModule(new AppModule(this)).httpModule(new HttpModule()).build();
    }
    @Inject
    HomePresenter mHomePresenter;
    @Inject
    ProgressDialog mProgressDialog;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        DaggerHomeComponent.builder()
                .appComponent(MyApplication.get(this).getAppComponent())
                .homeModule(new HomeModule(this))
                .build()
                .inject(this);
        mHomePresenter.requestData();
    }
    @Override
    public void showloading() {
        mProgressDialog.show();
    }
    @Override
    public void showDismiss() {
        mProgressDialog.dismiss();
    }
    @Override
    public void showError(String msg) {
        mProgressDialog.dismiss();
        Toast.makeText(this, "" + msg, Toast.LENGTH_SHORT).show();
    }
    @Override
    public void showResult(String list) {
        Toast.makeText(this, "SUCCESS:" + list.toString(), Toast.LENGTH_SHORT).show();
    }
    @Override
    public void showNoData() {
        Toast.makeText(this, "" + "数据NULL", Toast.LENGTH_SHORT).show();
    }
}
