In AnimatorInflater.java I found what many imports is red, so I think Android Studio cannot find these dependenscies. AnimatorInflater.java imports So I thing maybe some implimentations is wrong: https://github.com/Panicia/MVVMlearning1/blob/main/app/build.gradle
CodePudding user response:
That's because you use an Interpolator as the app:enterAnim
and app:exitAnim
. Interpolator "defines the rate of change of an animation", which means it's not an animation itself. Just update the app:enterAnim
and app:exitAnim
with some animations and it should solve the problem - examples here: Set animations.
