Answer 1

因为你把依赖关系搞砸了。您必须完全迁移到AndroidX依赖项，或者继续使用支持库依赖项。因此，而不是

implementation "android.arch.persistence.room:runtime:$room_lib"
annotationProcessor "android.arch.persistence.room:compiler:$room_lib"

使用

implementation "androidx.room:room-runtime:2.0.0-alpha1"
annotationProcessor "androidx.room:room-compiler:2.0.0-alpha1"

还要确保检查gradle.properties项目文件以包含

android.useAndroidX=true
android.enableJetifier=true
