Android 的数据绑定是否适用于 Transitions/Scenes 框架？

Question

Android的DataBinding library work with the Transitions framework吗？

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

尝试上面的代码会引发此错误：view tag isn't correct on view:null

Answer 1

您必须使用 DataBindingUtil.inflate()

自行扩充视图

并用膨胀的视图构建场景。 https://developer.android.com/reference/android/transition/Scene.html#Scene(android.view.ViewGroup, android.view.ViewGroup)

.bind(this) 仍然失败，因此您必须手动管理生成的绑定。

Answer 2

您应该在创建场景之前绑定布局：

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

bind(this) 失败，因为 this 不是绑定视图。 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));
