将自定义对象添加到自定义对象内的列表字段中

时间：2016-03-10 10:24:52

标签： java android list arraylist

我正在尝试将对象自定义为列表，这是另一个自定义对象中的字段。

让我解释一下调查问题。我有一个客户（公司）的arraylist这些客户有联系人（在客户工作的联系人）。出于这个原因，我试图将这些联系人添加到客户端对象内的arraylistfield。但我不知道如何将这些添加到所选客户端的arraylist或如何通过初始化调用clientsobjectclass中的方法，因为构造函数会询问所有客户端字段。

客户对象：

package Activities.Main.Objects;

import android.util.Log;
import Main.Arrays.ClientsArray;

import java.util.ArrayList;
import java.util.List;

                   String PostalAddress, String PostalCity, String PostalZipcode, String PostalCountry){

    }


    public void add(){
        Contactlist.add(new Contacts("Oscar", "Hugo", "Bokhorst", "Developer", "0616397853", "0513631325", "oscarbokhorst@gmail.com"));

    }


    public String getName() {

    public List<Contacts> getContactlist(){

我想将联系人添加到客户端（atm仍然是一个单独的数组，但它们需要链接到客户端）

    }

    public void setLocation(int location) {

我通过联系人列表查看我的客户端的位置，我在其中设置客户端位置并将其提供给AddContactsFragment。

使用构造函数也分配ArrayList<Contacts>。在你片段或活动中创建一个新列表 - 

List<Contacts> Contactlist =  new ArrayList<Contacts>();

然后将此所有联系人添加到此特定客户的此列表中。

然后，当您使用其余详细信息创建Client类对象时，只需将其传递给构造函数 - 

Client c = new Client(name, phone, ......... , Contactlist);

在Client类中修改构造函数以接受列表 - 

public Clients(String name, String phone, .......... , List Contactlist){
    this.Contactlist = Contactlist; //List assigned
}

如果您想在此列表中添加更多联系人，只需通过getter方法访问列表并添加更多联系人 - 

client.getContactList().add(contact);
