我有可以打开3个不同片段的父片段，3个片段中的每一个都可以更新父片段中的相同字段。 所以我创建了超级简单的监听器：
public interface RatingUpdatedListener extends Serializable{
//allow to set new rating from Gallery, Details, PersonalModel fragments into MyProfileFragment
void onRatingUpdated(int rating);
}
当我加载任何子片段时，我通过FragmentA.setArguments（bundle）
添加Bundle bundle = new Bundle();
bundle.putSerializable(RATING_LISTENER, mRatingListener);
fragment.setArguments(bundle);
和内部父片段我实现了这个监听器
private RatingUpdatedListener mRatingListener = new RatingUpdatedListener() {
@Override
public void onRatingUpdated(int rating) {
}
};
然后在子片段中我抓住了这个监听器：
mRatingUpdatedListener = (RatingUpdatedListener) getArguments().getSerializable(MyProfileFragment.RATING_LISTENER);
当我在其中一个子片段中使用本机android方法打开CameraActivity或GalleryActivity时出现问题，我得到了：

如果我的听众没有任何对象，问题为什么在NotSerializableException失败？
