点击后面

HomeViewModel:Warning:HomeViewModel 0 received: Destroyed FirstView for viewmodel 0 SubViewModel:Warning:SubViewModel 0 received: Destroyed FirstView for viewmodel 0 FirstViewModel:Warning:FirstViewModel 0 received: Destroyed FirstView for viewmodel 0 HomeViewModel:Warning:HomeViewModel 0 received: Destroyed SubFrag for viewmodel 0 SubViewModel:Warning:SubViewModel 0 received: Destroyed SubFrag …
