我在我的项目中使用Dagger 2 . 我在项目中有几个模块 . 我有一个连接到每个Activity模块的BaseActivityModule . 如何在BaseActivityModule中获取AppCompatActivity .
When compiling a project, I get this error
错误：[Dagger / MissingBinding] [dagger.android.AndroidInjector.inject（T）]如果没有@Inject构造函数或@ Provide-annotated方法，则无法提供android.app.AlertDialog . 公共抽象接口AppComponent {^ android.app.AlertDialog注入com.example.laptop.daggerexample.ui.main.view.MainActivity.alertDialog com.example.laptop.daggerexample.ui.main.view.MainActivity注入匕首.android.AndroidInjector.inject（T）组件路径：com.example.laptop.daggerexample.di.component.AppComponent？ com.example.laptop.daggerexample.di.builder.ActivityBuilder_BindMainActivity.MainActivitySubcomponent
Example below modules in the project
ActivityBuilder
@Module
abstract class ActivityBuilder {
@ContributesAndroidInjector(modules = [(MainActivityModule::class)])
abstract fun bindMainActivity(): MainActivity
}
AppModule
@Module
abstract class AppModule{
@Provides
@Singleton
fun provideContext(application: Application): Context = application
}
BaseActivityModule
@Module
class BaseActivityModule {
@Provides
fun provideAlertDialog(activity: AppCompatActivity)=
AlertDialog.Builder(activity).create()
}
MainActivityModule
@Module(includes = [(BaseActivityModule::class)])
class MainActivityModule {
@Provides
fun provideMainMVPView(activity: MainActivity): MainMVPView = activity
@Provides
fun provideMainMVPPresenter(presenter: MainPresenter<MainMVPView>):
MainMVPPresenter<MainMVPView> = presenter
}
