如何使用新的androidx.lifecycle:*:2.2.0-alpha01获取lifecycle.coroutineScope [英] How to get lifecycle.coroutineScope with new androidx.lifecycle:*:2.2.0-alpha01

问题描述

2019年5月7日androidx.lifecycle:*:2.2.0-alpha01发布，宣布:

On 7th May, 2019 androidx.lifecycle:*:2.2.0-alpha01 was released announcing:

此版本增加了一些新功能，这些功能增加了对Lifecycle和LiveData的Kotlin协程的支持.可以在此处找到有关它们的详细文档.

This release adds new features that adds support for Kotlin coroutines for Lifecycle and LiveData. Detailed documentation on them can be found here.

在文档中，提到我可以得到LifecycleScope :

On documentation it's mentioned that I can get the LifecycleScope:

通过lifecycle.coroutineScope或lifecycleOwner.lifecycleScope属性

但是似乎我找不到它们.我目前的依赖条件是:

But it seems that I'm not able to find none of them. My current dependencises are:

def lifecycle_ver = "2.2.0-alpha01"
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_ver"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_ver"
implementation "androidx.lifecycle:lifecycle-common-java8:$lifecycle_ver"

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.2.1'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.2.1'

可能是什么原因以及如何获得这些API?

What may be the cause and how do get these apis?

推荐答案

我实际上花了几个小时试图自己弄清楚这一点，结果发现它在一个仅存在于alpha版本的新程序包中.添加此内容，您应该就很好了.

I actually spent a couple hours trying to figure this out myself and it turns out it is in a new package that only exists as of the alpha. Add this and you should be good to go.

implementation "androidx.lifecycle:lifecycle-runtime-ktx:$lifecycle_ver"
