Androidstudiobuild导航组件出错，action不是抽象的，也没有实现抽象的成员actionID

html5 • • 问答

不知何故，构建崩溃了，并出现了与导航组件相关的奇怪错误，尽管它以前可以工作，但错误出在生成的类中，就我而言 NativeLanguageSelectionFragmentDirections

这是错误

e: C:UsersDavidStudioProjectsandroidappbuildgeneratedsourcenavigation-argsdebugcomlinguisticlinguisticframeworkpresentationloginscreensuimainNativeLanguageSelectionFragmentDirections.kt: (10, 16): Class 'GoToSelectLearningLangAction' is not abstract and does not implement abstract member public abstract val actionId: Int defined in androidx.navigation.NavDirections

这是导航图的代码

我在用

 "androidx.navigation:navigation-fragment-ktx:2.3.5"
 "androidx.navigation:navigation-ui-ktx:2.3.5"

回答

我也有这个问题。直到他们发布修复程序。请试试这个：

plugins {
  id("androidx.navigation.safeargs")
}

代替

plugins {
  id("androidx.navigation.safeargs.kotlin")
}

回答

由于版本v2.4.0-alpha02已发布，此已知错误不再存在。

Bug修复

  • 尝试在 Kotlin 中生成方向属性时，Safe Args 不再崩溃。( Id2416 , b/188564435 )
以上是Androidstudiobuild导航组件出错，action不是抽象的，也没有实现抽象的成员actionID的全部内容。
