Android的DataBinding是否適用於Transitions/Scenes框架？

Question

Android的DataBinding庫的工作是否與Transitions framework？

 Scene scene = Scene.getSceneForLayout(this, R.layout.creditcardentryview_scene2_expanded, this.getContext()); 
     TransitionManager.go(scene); 
     scene2Binding = CreditcardentryviewScene2ExpandedBinding.bind(this); 

嘗試上面的代碼拋出這個錯誤：view tag isn't correct on view:null

Answer 1

你應該佈局結合創建場景之前：

CreditcardentryviewScene2ExpandedBinding binding = CreditcardentryviewScene2ExpandedBinding.inflate(getLayoutInflater(), this, false); 
Scene scene = new Scene(this, binding.getRoot()); 
TransitionManager.go(scene); 

的bind(this)失敗，因爲this並不是一個綁定視圖。 this是場景根！所以你也可以這樣做：

Scene scene = Scene.getSceneForLayout(this, R.layout.creditcardentryview_scene2_expanded, this.getContext()); 
TransitionManager.go(scene); 
scene2Binding = CreditcardentryviewScene2ExpandedBinding.bind(this.getChildAt(0)); 

Answer 2

你必須自己膨脹的觀點與DataBindingUtil.inflate()

，並與膨脹的觀點構建了現場。 https://developer.android.com/reference/android/transition/Scene.html#Scene(android.view.ViewGroup，android.view.ViewGroup）

.bind(this)雖然仍然失敗，所以你必須手動管理生成的綁定。
