我是android kotlin新手,在我的OCR应用程序中使用viewModel。“import androidx.fragment.App.viewModels”未显示。我已添加了所有必要的依赖项。我做错了什么 这里是依赖项Android 未解析的引用:viewModels,android,kotlin,viewmodel,android-viewmodel,kotlin-android-extensions,Android,Kotlin,Viewmodel,Android Viewmodel,Kotlin Android Extensions,我是android kotlin新手,在我的OCR应用程序中使用viewModel。“import androidx.fragment.App.viewModels”未显示。我已添加了所有必要的依赖项。我做错了什么 这里是依赖项 dependencies { implementation fileTree(dir: "libs", include: ["*.jar"]) implementation "org.jetbrains.

这就是导入错误
添加此依赖项以在片段中使用viewModels():
implementation 'androidx.fragment:fragment-ktx:1.2.5'
您应该检查此项,以便开发人员知道其已回答:/
