问题
I am injecting Presenter to BookDashboard(Activity) and BookDashboardPresenter class require an MvpView
interface
in it's constructor .
When i run
AppComponent
@Component(
modules = [
AndroidInjectionModule::class,
ActivityBuilder::class
]
)
@Singleton
interface AppComponent : AndroidInjector<App> {
@Component.Builder
interface Builder {
fun addContext(@BindsInstance context: Context): Builder
fun addBookEngine(@BindsInstance bookEngineModule: BookEngineModule) :Builder
fun build(): AppComponent
}
}
ActivityBuilder.kt
@Module
abstract class ActivityBuilder {
@ContributesAndroidInjector(modules = {BookEngineModule.class})
public abstract BookDashboard bindBookDashboard();
}
BookEngineModule.kt
@Module
class BookEngineModule(val mvpView: BookDashboardContract.MvpView){
@Provides
fun providePresenter():BookDashboardContract.Presenter{
return BookDashboardPresenter(mvpView)
}
}
BookDashboardContract
interface BookDashboardContract {
interface MvpView{
fun displayBooks()
fun showProgress()
fun hideProgress()
}
interface Presenter{
fun fetchedBooks()
}
}
BookDashboardPresenter.kt
class BookDashboardPresenter @Inject constructor(val viewContract:BookDashboardContract.MvpView) : BookDashboardContract.Presenter{
val bookInteractor = BookInteractor(this)
override fun fetchedBooks() {
bookInteractor.fetchDataFromServer()
viewContract.displayBooks()
}
}
BookDashboard -> Activity
class BookDashboard : DaggerAppCompatActivity(),BookDashboardContract.MvpView{
@Inject
lateinit var presenter: BookDashboardContract.Presenter
override fun onCreate(savedInstanceState: Bundle?) {
DaggerAppComponent.builder().addContext(this).
addBookEngine(BookEngineModule(this)).build()
super.onCreate(savedInstanceState)
///presenter.fetchedBooks()
}
override fun displayBooks() {
Toast.makeText(this,"Books Displayed",Toast.LENGTH_LONG).show()
}
override fun showProgress() {}
override fun hideProgress() {}
}
But when I build the project I am having below error
ActivityBuilder_BindBookDashboard.java:24: error: @Subcomponent.Factory method is missing parameters for required modules or subcomponents: [quiz.mania.trivia.mcq.question.di.BookEngineModule]
interface Factory extends AndroidInjector.Factory<BookDashboard> {}
DaggerClass
@Module(subcomponents = ActivityBuilder_BindBookDashboard.BookDashboardSubcomponent.class)
public abstract class ActivityBuilder_BindBookDashboard {
private ActivityBuilder_BindBookDashboard() {}
@Binds
@IntoMap
@ClassKey(BookDashboard.class)
abstract AndroidInjector.Factory<?> bindAndroidInjectorFactory(
BookDashboardSubcomponent.Factory builder);
@Subcomponent(modules = BookEngineModule.class)
public interface BookDashboardSubcomponent extends AndroidInjector<BookDashboard> {
@Subcomponent.Factory
interface Factory extends AndroidInjector.Factory<BookDashboard> {}
}
}
above class can't resolve BookEngineModule and BookDashboard
What am i missing ?
