}

ChatIntentParamenters params = new ChatIntentParamenters(title, additionalTitle, canCreateGroups, canCreateMessages, canDeleteMessages, false, contactsList);
intent.putExtra(ConversationListActivity.INTENT_PARAMS, params);
getActivity().startActivity(intent);

当我在活动中获得意向性额外时,我有一个错误：

ChatIntentParamenters params = intent.getParcelableExtra(INTENT_PARAMS);

Answer 1

尝试替换

this.preloadedContacts = parcel.readArrayList(PlatformContact.class.getClassLoader())

与

    this.preloadedContacts= new ArrayList<>();
    parcel.readTypedList(this.preloadedContacts, PlatformContact.CREATOR);

而且

    dest.writeList(preloadedContacts);

    dest.writeTypedList(preloadedContacts)
