模型 class 的对象列表中的数据未正确检索？

Question

当我尝试从 listConCard 中检索单个对象时（在我的 activity class ContactCard.class 中），"conName" 对于所有 contactCards 都正确接收但我没有从其兄弟数组 "conPhoneType"、"conPhoneValue"、"conEmailType"、"conEmailValue".

获取正确数据

listConCard 是我的模型的对象列表 class ContactCardModel.class.

我正在 listConCard 中添加 "ContactCardModel" 个对象，如下所示

listConCard.add(new ContactCardModel(conName, conPhoneType, conPhoneValue, conEmailType, conEmailValue));

并按如下方式检索 "ContactCardModel" 个对象的数据

for(int i = 0; i < listConCard.size(); i++){

    Log.e("InAdp", listConCard.get(i).getConName()); // name is returing correctly.

    for(int x = 0; x < listConCard.get(i).getConPhoneType().size(); x++)
        Log.e("InAdp conPhone", listConCard.get(i).getConPhoneType().get(x) + ": " + listConCard.get(i).getConPhoneValue().get(x)); 


    for(int x = 0; x < listConCard.get(i).getConEmailType().size(); x++)
        Log.e("InAdp conEmail", listConCard.get(i).getConEmailType().get(x) + ": " + listConCard.get(i).getConEmailValue().get(x));

}

数组 getConPhoneType 和 getConPhoneValue 的值都返回 0 个元素

数组 getConEmailType 和 getConEmailValue 的值都返回 1 个元素

conPhoneType 和 conPhoneValue 的大小相同

conEmailType 和 conEmailValue 的大小相同

ContactCard.class

String conName;
List<String> conPhoneType;
List<String> conPhoneValue;
List<String> conEmailType;
List<String> conEmailValue;
List<ContactCardModel> listConCard;

int i = 1;

    for (AddressBookContact addressBookContact : list) {

        conName = addressBookContact.name;

        conPhoneType.clear();
        conPhoneValue.clear();
        if(addressBookContact.phones != null) {

            for (int x = 0; x < addressBookContact.phones.size(); x++) {
                int type = (int) addressBookContact.phones.keyAt(x);
                String typeName = (String) ContactsContract.CommonDataKinds.Phone.getTypeLabel(addressBookContact.res, type, "");
                String phValue = addressBookContact.phones.valueAt(x);

                conPhoneType.add(typeName);
                conPhoneValue.add(phValue);
            }

                conEmailType.add(typeName);
                conEmailValue.add(emailValue);
            }

尝试以下修改。无法运行和测试代码，因为提供的代码不足以编译和运行。在ContactCard.java

String conName;
List<String> conPhoneType;
List<String> conPhoneValue;
List<String> conEmailType;
List<String> conEmailValue;
List<ContactCardModel> listConCard = new ArrayList<ContactCardModel>();

int i = 1;

    for (AddressBookContact addressBookContact : list) {

        conName = addressBookContact.name;

        conPhoneType = new ArrayList<String>();
        conPhoneValue = new ArrayList<String>();
        if(addressBookContact.phones != null) {

            for (int x = 0; x < addressBookContact.phones.size(); x++) {
                int type = (int) addressBookContact.phones.keyAt(x);
                String typeName = (String) ContactsContract.CommonDataKinds.Phone.getTypeLabel(addressBookContact.res, type, "");
                String phValue = addressBookContact.phones.valueAt(x);

                conPhoneType.add(typeName);
                conPhoneValue.add(phValue);
            }
        }

        conEmailType = new ArrayList<String>();
        conEmailValue = new ArrayList<String>();
        if(addressBookContact.emails != null){

            for(int x = 0; x < addressBookContact.emails.size(); x++){
                int type = (int) addressBookContact.emails.keyAt(x);
                String typeName = (String) ContactsContract.CommonDataKinds.Phone.getTypeLabel(addressBookContact.res, type, "");
                String emailValue = addressBookContact.emails.valueAt(x);

                conEmailType.add(typeName);
                conEmailValue.add(emailValue);
            }
        }

        listConCard.add(new ContactCardModel(conName, conPhoneType, conPhoneValue, conEmailType, conEmailValue));

    }

在ContactCardModel.java

的构造函数中

public ContactCardModel(String mConName, List<String> mConPhoneType, List<String> mConPhoneValue,
                    List<String> mConEmailType, List<String> mConEmailValue){

this.conName = mConName;
this.conPhoneType = mConPhoneType;
this.conPhoneValue = mConPhoneValue;
this.conEmailType = mConEmailType;
this.conEmailValue = mConEmailValue;

}
