android - 如何用 Toothpick 注入(inject) Map<> 或 Set<> (dagger 2 multibindings)

Question

Dagger 2 能够使用多重绑定(bind)注入(inject)集合或映射。 如何在 Toothpick 中做到这一点

例如我想要 @Inject constructor(val map: Map<String, ISyncRepository>)

Answer 1

它可能是这样的:

   @Binds
   @IntoMap
   @TheMapKey(“your key”)
   abstract fun getSyncRepository() : ISyncRepository

看下面2个例子

对于

@Inject constructor(

     private val creators: Map<Class<out ViewModel>, @JvmSuppressWildcards 
         Provider<ViewModel>>

) 

使用:

@Binds
@IntoMap
@ViewModelKey(UserViewModel.class)
abstract ViewModel bindUserViewModel(UserViewModel userViewModel);
