“无效的符号名称"Android Studio崩溃后 [英] "invalid symbol name" after Android Studio crashed

问题描述

我正在Android Studio中编辑布局，并添加了一个Switch.我首先将其ID设置为"switch".发生编译错误后，我意识到这是一个保留关键字，无法使用，因此我决定将其ID更改为"mySwitch"，但此时Android Studio崩溃了.

I was editing a layout in Android Studio and added a Switch. I first set its ID to "switch". After a compilation error, I realized it was a reserved keyword and I cannot use it, so I decided to change its ID to "mySwitch" but Android Studio crashed at this moment.

再次启动它后，我检查了ID，该ID确实已更改为"mySwitch"，但是在尝试编译时，仍然出现此错误:

After launching it again, I checked the ID, which does have been changed to "mySwitch", but when trying to compile, I still get this error:

/path/to/app/build/generated/source/r/debug/com/example/program/R.java: error: invalid symbol name 'com.example.program:id/switch'.

我猜想Android Studio在崩溃前并没有更改"switch"的所有出现，但我没有发现任何变化.

I guess Android Studio did not change all occurences of "switch" before crashing, but I did not find any.

我尝试了但没用的东西:

What I tried but did not work :

• 再次更改ID
• 删除并再次添加Switch
• 清洁项目

我没有想到的我的Switch ID是否发生了?

Is there any occurence of my Switch ID I did not think of ?

推荐答案

我发现了问题，我应该早点想到的.
我所做的是右键单击"my_layout.xml" > 分析> 检查代码...

I found the problem, I should have thought of that earlier.
What I did is right click on "my_layout.xml" > Analyze > Inspect Code...

然后它向我显示了这一行

Then it showed me this line

app:layout_constraintEnd_toStartOf="@+id/switch"

我不知道我怎么想念...

I don't know how I missed that...
