如何在mainModule类中提供活动上下文？谢谢！代码如下所示：
@H_403_2@@Singleton
@Component(modules = {AndroidInjectionModule.class,AppModule.class,ActivityBuilder.class})
public interface AppComponent {
@Component.Builder
interface Builder {
@BindsInstance
Builder application(Application application);
AppComponent build();
}
void inject(MvmApp app);
}
Activtity builder：
@H_403_2@@Module public abstract class ActivityBuilder { @ContributesAndroidInjector(modules = {MainModule.class}) abstract MainActivity bindMainActivity(); }我有一个appModule,每个活动都有一个模块：
@H_403_2@@Module public class AppModule { @Provides @Singleton @ApplicationContext Context provideContext(Application application) { return application; } @Provides @Singleton DataManager provideDataManager(AppDataManager appDataManager) { return appDataManager; } @Provides @DatabaseInfo String provideDatabaseName() { return "carDatabase"; } @Provides @Singleton AppDataBase provideAppDatabase(@DatabaseInfo String dbName,@ApplicationContext Context context) { return Room.databaseBuilder(context,AppDataBase.class,dbName) .build(); } @Provides @Singleton DbHelper provideDbHelper(AppDbHelper appDbHelper) { return appDbHelper; } }AppClass：
@H_403_2@public class MvmApp extends Application implements HasActivityInjector { @Inject DispatchingAndroidInjector<Activity> activityDispatchingAndroidInjector; @Override public void onCreate() { super.onCreate(); DaggerAppComponent.builder() .application(this) .build() .inject(this); } @Override public DispatchingAndroidInjector<Activity> activityInjector() { return activityDispatchingAndroidInjector; } }我的所有活动都扩展了基础活动,注入了Dagger家属.
@H_403_2@public abstract class BaseActivity extends AppCompatActivity implements MvpView { @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); AndroidInjection.inject(this); } }在mainModule中,我需要提供活动的上下文.
@H_403_2@@Module public class MainModule { @Provides MainMvpPresenter<MainMvpView> provideMainPresenter( MainPresenter<MainMvpView> presenter) { return presenter; } @Provides CompositeDisposable provideCompositeDisposable() { return new CompositeDisposable(); } @Provides CarAdapter provideCarAdapter( @ActivityContext Context context) { return new CarAdapter(context); } }解决方法
解决方案是：
@H_403_2@@Module
public class MainModule {
@Provides
MainMvpPresenter<MainMvpView> provideMainPresenter(
MainPresenter<MainMvpView> presenter) {
return presenter;
}
@Provides
CompositeDisposable provideCompositeDisposable() {
return new CompositeDisposable();
}
@Provides
CarAdapter provideCarAdapter(MainActivity activity) {
return new CarAdapter(activity);
}
}
