【问题描述】：
我正在构建一个应用程序，我必须在其中通过Intent 传递List<Object>。
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;
}
}
这是我尝试通过Intent传递的数据：
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 没有实现Serializable。我该如何解决？
logcat 输出：

【问题讨论】：
-
也添加崩溃日志
-
您可能是对的，问题在于
object不可序列化。创建自己的可序列化类，并从它继承。 -
你能发布你的
items模型类吗？ -
它实现了可序列化
