我今天遇到了完全相同的问题,并且能够解决。事实证明,问题是androidx.lifecycle:lifecycle-viewmodel“失败”类所在的模块使用的预期版本与其他一些相关代码中的更高版本之间的版本不匹配。
因此,就我而言,我的模块使用的是该模块的2.1.0版,但其中一个依赖项使用的是2.2.0版。代码会编译没有问题,因为gradle解决了对最新版本的依赖;然而,Android Studio 不知何故对这种情况感到困惑(并非总是如此,因为这不会一直发生,但有时——这不是我第一次看到这种情况。)
因此,解决方案是:找出您的应用程序中该库的最新版本,并更新您build.gradle的此模块以指向 gradle 解析到的相同版本。或者:
gradlew app:dependencies lifecycle-viewmodelbuild.gradle您的应用程序以依赖于lifecycle-viewmodelgradle 说它正在解决的版本mrt*_*xaz 19
在我的情况下(一个 Android 模块),Android Studio 4.0.1,我在 IDE 中收到了一些与 androidx.lifecycle.HasDefaultViewModelProviderFactory 相关的警告,我通过将这一行添加到 build.gradle 解决了这个问题:
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'

因此 build.gradle 的开头变为:
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'

androidx.fragment:fragment-ktx:x.x.x使用实际版本将依赖项添加到您的构建 gradle 中。对于活动,您必须添加androidx.activity:activity-ktx:x.x.x. 我希望这对您有所帮助,就我而言,它解决了问题。
