Android如何将对象用户传递给 Activity fragment

Question

Intent mIntent = new Intent(Login.this, PlatformActivity.class);
                Bundle bundle = new Bundle();
                bundle.putSerializable("user",user);
                mIntent.putExtras(bundle);
                startActivity(mIntent);

public class User implements Serializable {

    private List<UserAccount> userAccountList;
    ...
    ...
}

RuntimeException:Parcelable 遇到IOException 写入可序列化对象(name = com.orbis.mobile.User)

User 是不可序列化的，我想知道如何用 arrayList 传递 Object。如果用户没有设置userAccountList，它可以工作。

Answer 1

            ArrayList<UserAccount> userAccountList = user.getUserAccountList();
            user.setUserAccountList(null);

            bundle.putSerializable("user", user);

            bundle.putSerializable("accountList", userAccountList);

            mIntent.putExtras(bundle);
            startActivity(mIntent);


    user = (User) getIntent().getSerializableExtra("user");

    ArrayList<UserAccount> accountNumberList = (ArrayList<UserAccount>) getIntent().getSerializableExtra("accountList");

    user.setUserAccountList(accountNumberList);
