java - Parcelable 在 Intent putExtra 上写入可序列化对象时遇到 IOException

Question

我正在构建一个应用程序，我必须在其中传递 List<Object>通过Intent 。

我的代码:

public class ObjectModelWrapper implements Serializable{

    private List<Object> objectModel;

    public ObjectModelWrapper(List<Object> objectModel) {
        this.objectModel = objectModel;
    }

    public List<Object> getObjectModel() {
        return objectModel;
    }
}

这是我尝试传递的数据 Intent :

holder.categoryAction.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                firstSix = new ArrayList<>();
                newList = new ArrayList<>();
                if (items.get(position).getGames().size() > 12) {
                    firstSix.addAll(items.get(position).getGames().subList(0, 6));
                    newList.add(firstSix);
                    newList.add(items.get(position).getBannerImage());
                    newList.add(items.get(position).getGames().subList(6, items.get(position).getGames().size()));
                }else if (items.get(position).getGames().size() > 8 && items.get(position).getGames().size() < 12) {
                    firstSix.addAll(items.get(position).getGames().subList(0, 6));
                    newList.add(firstSix);
                    newList.add(items.get(position).getBannerImage());
                    newList.add(items.get(position).getGames().subList(6, items.get(position).getGames().size()));
                }else if (items.get(position).getGames().size() > 3 && items.get(position).getGames().size() < 8) {
                    firstSix.addAll(items.get(position).getGames().subList(0, 3));
                    newList.add(firstSix);
                    newList.add(items.get(position).getBannerImage());
                    newList.add(items.get(position).getGames().subList(3, items.get(position).getGames().size()));
                }else {
                    firstSix.addAll(items.get(position).getGames().subList(0, 1));
                    newList.add(firstSix);
                    newList.add(items.get(position).getBannerImage());
                    newList.add(items.get(position).getGames().subList(1, items.get(position).getGames().size()));
                }
                ObjectModelWrapper wrapper = new ObjectModelWrapper(newList);

                for (int i=0; i< firstSix.size(); i++){
                    Log.e("GAME NAME FIRST SIX", firstSix.get(i).getName());
                }

                for (int i=0; i< newList.size(); i++){
                    Log.e("GAME NAME NEW LIST", newList.get(i).toString());
                }
                Intent intent = new Intent(context, CategoryInfo.class);
                intent.putExtra("categoryColor", items.get(position).getCategoryLineColor());
                intent.putExtra("categoryBanner", items.get(position).getBannerImage());
                intent.putExtra("categoryName", items.get(position).getCategoryName());
                intent.putExtra("customList", wrapper);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(intent);
            }
        });

新列表是:

private transient List<Object> newList;

我知道这可能是因为 Object尚未实现Serializable 。我该如何解决这个问题？
