共享元素过渡到包含 ViewPager 的片段

Question

我正在尝试执行从 Fragment A 中的 RecyclerView 项目到 Fragment B 的共享元素转换。转换名称设置在两种布局的最外层 CardView 上。我的实现与this示例中的实现基本相同。

一切正常，直到我在 Fragment B 中添加了一个 ViewPager2。

我尝试按照答案中的步骤操作，但没有成功。

Answer 1

错误是在 androidx.fragment:fragment:1.3.4 上引入的。要修复它，您需要手动更新到 androidx.fragment:fragment:1.3.5 或 androidx.fragment:fragment-ktx:1.3.5.

根据release notes

Fixed a regression in shared element transitions introduced in Fragment 1.3.4 by aosp/1679887. Fragments now correctly handle transition groups (either set directly via transitionGroup="true" or indirectly via a transitionName or background) and shared elements will no longer throw IndexOutOfBoundsExceptions. (I16484, b/188679569, b/188969304)

Answer 2

添加对 androidx.fragment:fragment-ktx:1.4.0-alpha03 的依赖解决了这个问题。不再需要添加空视图。

release notes 声明如下：

From Fragment 1.3.5: Fixed a regression in shared element transitions introduced in Fragment 1.3.4 by aosp/1679887. Fragments now correctly handle transition groups (either set directly via transitionGroup="true" or indirectly via a transitionName or background) and shared elements will no longer throw IndexOutOfBoundsExceptions.
