问题描述

就我而言，就像这样的这样的源代码

in my case, it's like this source code like this

然后，我单击下载源"，但看到此错误: 错误

then, I click "download source" , but see this error: error

我确定我的网络正常.对于许多其他库来说，这还可以.所以，我对此感到困惑.有人可以告诉我为什么会发生问题吗?我还想知道android studio如何下载源代码并附加它们，为此有任何文档吗?

I'm sure my network is ok. And for many other libraries this is OK.SO,I'm confused of this.Can someone tell me why problem happened ? I also want to know how android studio download source code and attach them , is there any document for this？

推荐答案

由于某些未知原因，当前的 ConstraintLayout 依赖项(请参阅您的 build.gradle )没有提供源代码！我正在使用"hack":

For some unknown reason, the current ConstraintLayout dependency (see your build.gradle) does not ship with source! I am using a 'hack':

(A)使用浏览器将正式文档保存到路径取决于您的SDK位置的文件中. (您将必须创建任何空的中间文件夹).

(A) Use your browser to save the official documentation to a file whose path depends on your SDK location. ( You will have to create any empty intermediate folders).

https://developer.android.com/reference/androidx/constraintlayout/widget/ConstraintLayout
file:///[your SDK]/docs/reference/androidx/constraintlayout/widget/ConstraintLayout.html

(B)在Android Studio Project 视图中，单击 外部文件 并导航至您的依赖项.例如:

(B) From Android Studio Project view click External Files and navigate to your dependency. eg:

Gradle: androidx.constraintlayout:constraintlayout:2.0.0-beta3@aar

(C)右键单击-> 库属性 -> 指定文档URL :

(C) Right click -> Library properties -> Specify documentation URL:

file:///[your SDK]/docs/reference

不是很好，但是总比没有好.我针对 MotionLayout 和其他一些内容重复了此操作.

Not great, but better than nothing. I repeated it for MotionLayout and a few others.
