Can't seem to launch Layout Inspector on Android Studio 3.0 (Canary 3)

似乎无法在Android Studio 3.0 (Canary 3)上推出布局检查器

When connected to my device and app running, choosing Tools > Android > Layout Inspector comes up with the following error dialog:

当连接到我的设备和app运行时,选择工具> Android > Layout Inspector,会出现以下错误对话框:

"Error obtaining view hierarchy: Unexpected error: empty view hierarchy"

“获取视图层次结构的错误:意外错误:空视图层次结构”

无法启动Android Studio布局检查器:“意外错误:空视图层次结构”

Any setup I'm missing? I have Developer Options enabled on the device.

设置我失踪吗?我在设备上启用了开发人员选项。

I can't launch my hierarchy viewer while playing video. Once I pause the video, it works!

我不能在播放视频时启动层级查看器。一旦我暂停视频,它就可以工作了!

If you have ViewTreeObserver in your code to measure a view's width/height, and you're changing some width/height/padding/etc. according to a result you are getting from addOnPreDrawListener of ViewTreeObserver;

如果在代码中有ViewTreeObserver来度量视图的宽度/高度,并且您正在更改一些宽度/高度/填充等等。根据来自ViewTreeObserver的addOnPreDrawListener的结果;

Just comment inside onPreDraw or comment all code related to ViewTreeObserver.

只需要在onPreDraw或注释中注释所有与ViewTreeObserver相关的代码。

This could be related to your Android version. For example, in my case, this error occurs on Genymotion on Android 4. After moving to Android 5 this error gone.

这可能与你的Android版本有关。例如,在我的例子中,这个错误发生在Android 4上的Genymotion上。在移动到Android 5之后,这个错误消失了。

Had same problem on Android Studio v2.3.3, problem was related to CountDownTimer Object, somehow it cause problem (probably because of onTick method). After commenting it, I could normally use Layout Inspector. Maybe you use something similar in your code, try to comment it out and see if if works.

在Android Studio v2.3.3上也有同样的问题,问题与CountDownTimer对象有关,不知何故导致了问题(可能是因为onTick方法)。在注释之后,我通常可以使用Layout Inspector。也许你在代码中使用了类似的东西,试着注释掉它,看看是否有效。

In general I've this behavior when something is "moving" in the view so the layout inspector cannot retrieve a simple layout, that's why pausing a video will work but if you have something more complex like camera preview or Google Map is harder, not sure how to work around this

一般来说,当视图中有东西在“移动”时,我就会有这种行为,因此布局检查器不能检索简单的布局,这就是暂停视频的原因,但是如果你有更复杂的东西,比如camera preview或谷歌Map,就比较难了,不知道该如何解决这个问题
