匕首2有能力注入集合或映射与多重绑定。
用牙签怎么做
例如我想要@Inject constructor(val map: Map<String, ISyncRepository>)
最佳答案
可能是:
@Binds
@IntoMap
@TheMapKey(“your key”)
abstract fun getSyncRepository() : ISyncRepository
看下面两个样本

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);
