仅在构造函数中注入某些参数 [英] Inject only certain params in constructor

问题描述

我有主持人

class PhonePresenter @Inject constructor(
    private val preference: DataPreference,
    private val ioScheduler: Scheduler = Schedulers.io())

ioScheduler 是默认参数。我只想注入 preference：DataPreference 。现在我有一个例外

ioScheduler is a default parameter. I want to inject only preference: DataPreference. Now I have the exception

[dagger.android.AndroidInjector.inject(T)] io.reactivex.Scheduler cannot be provided without an @Provides-annotated method.

有什么方法可以定义要注入到构造函数中的参数？

Is there any way to define parameters which I want to inject in a constructor?

推荐答案

使用辅助构造函数注入构造函数

Make inject constructor with secondary constructor

class PhonePresenter(
    private val preference: DataPreference,
    private val ioScheduler: Scheduler) {        
    @Inject consturctor(preference: DataPreference):this(perference, Schedulers.io())
}
