共享元素过渡重叠 BottomNavigationView

Question

我在我的 recyclerView 的 onItemClick 方法中使用 SharedElement Transition 去 DetailsActivity。但是，当单击底部的项目时，它首先位于顶部操作 BottomNavigationView 然后发生转换。 OnBackPressed 是一样的。它还在模拟器中的机械键之上。如何解决？

Answer 1

你可以试试这个；

<item name="android:windowSharedElementsUseOverlay">false</item>

注意：将这一行放到您的应用程序基础主题中的 styles.xml 文件中。
