意图不使用带有SharedElement过渡的onActivityReenter中的Parcelable对象

Question

我正在研究Android中的共享元素转换，并完美地执行了动画。我面临的问题是使用Intents传递数据时。因此，我基本上从ActivityA启动Intent，这是第一个包含回收站视图的屏幕，使用TransitionName执行ImageTransform并启动ActivityB，其中包含一个包含ViewPager的详细信息活动。现在，当我按下后退按钮时，ActivityB调用finishAfterTransition，我在其中创建一个Intent并将结果设置如下：

@Override
public void finishAfterTransition() {
    Intent data=new Intent();
    data.putExtra("Student", new Student("id", "name", "grade"));
    data.putExtra("CURRENT_POSITION", 2);
    data.putExtra("LAST_POSITION", 5);
    setResult(ProfileConstant.ResponseCode.COMPLETE_PROFILE, data);
    finishAfterTransition = true;
    super.finishAfterTransition();
}

学生模型与this link的答案相同。 在ActivityA中，我正在使用

 public void onActivityReenter(int resultCode, Intent data) {
        Student sr = (Student) bundle.getParcelable("Student");
        current_position = bundle.getInt("CURRENT_POSITION", -1);
        int last_position = bundle.getInt("LAST_POSITION", -1);
 } 

会抛出以下异常。

当我没有传递学生对象并且一切都按预期工作时，所有动画都完全正常，没有任何异常。我还使用setEnterSharedElementCallback和setExitSharedElementCallback来映射视图及其转换名称，这与Intent无关。

我不明白为什么在Intent中传递一个parcelable对象不适用于Transitions。有解决方法还是我做错了？会很感激的建议。我这里只提供了相关的代码。
