Question

当我尝试从listConCard（在我的活动类ContactCard.class中）中检索单个对象时，＆＃34; conName＆＃34;所有联系人卡都正确接收，但我没有从其兄弟阵列获得正确的数据＆＃34; conPhoneType＆＃34;，＆＃34; conPhoneValue＆＃34;，＆＃34; conEmailType＆＃34;，＆＃34; conEmailValue＆＃ 34。

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

我正在添加＆＃34; ContactCardModel＆＃34; listConCard中的对象如下

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

并检索＆＃34; ContactCardModel＆＃34;的数据对象如下

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));

}

两个数组的值getConPhoneType和getConPhoneValue都返回0个元素

两个数组的值getConEmailType和getConEmailValue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;

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.clear();
        conEmailValue.clear();
        if(addressBookContact.emails != null){

                String emailValue = addressBookContact.emails.valueAt(x);

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

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

    }

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

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;

}

模型类对象列表中的数据无法正确检索？
