解决无法使用by viewModels() by activityViewModels()

安卓开发过程使用kotlin开发LiveData和ViewModel时,有时候会遇到
Unresolved reference: viewModels
Unresolved reference: activityViewModels
一般只需要在build.gradle中补充一下就可以了

implementation "androidx.activity:activity-ktx:1.5.0-alpha03"
implementation "androidx.fragment:fragment-ktx:1.5.0-alpha03"

然后就可以使用 by viewModels()和by activityViewModels()
