Android的DataBinding是否适用于Transitions/Scenes框架？

Question

Android的DataBinding库的工作是否与Transitions framework？

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

尝试上面的代码抛出这个错误：view tag isn't correct on view:null

Answer 1

你应该布局结合创建场景之前：

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

的bind(this)失败，因为this并不是一个绑定视图。 this是场景根！所以你也可以这样做：

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

Answer 2

你必须自己膨胀的观点与DataBindingUtil.inflate()

，并与膨胀的观点构建了现场。 https://developer.android.com/reference/android/transition/Scene.html#Scene(android.view.ViewGroup，android.view.ViewGroup）

.bind(this)虽然仍然失败，所以你必须手动管理生成的绑定。
