我在尝试列出数据时收到此警告.有谁知道为什么?
I get this warning when I try to list data. Does anyone know why?
您指的是 Android 平台的内部注解,这些注解并不是您想要用于您自己的代码的注解.对于您的代码,您应该导入这些注释的 AndroidX 版本:
You're referring to the Android platform's internal annotations, which aren't the ones you want to use for your own code. For your code, you should import the AndroidX versions of those annotations:
androidx.annotation.NonNull
androidx.annotation.Nullable
等等.(注意 androidx
vs android
中额外的 x
)
etc. (note the extra x
in androidx
vs android
)
您还需要确保在 build.gradle
中声明了对 androidx.annotation:annotation
的依赖项(请参阅 这里获取最新版本信息)
You'll also want to make sure you have declared a dependency on androidx.annotation:annotation
in your build.gradle
(see here for the latest version information)
