黑莓列表联系人与电子邮件地址

Question

我正在使用此代码 sn-p 检索联系人的电子邮件地址，但我想做的是列出拥有电子邮件地址的联系人。使用此方法，它会显示所有联系人

try {
                list = (BlackBerryContactList) PIM.getInstance()
                .openPIMList(PIM.CONTACT_LIST, PIM.READ_ONLY);

                PIMItem contact = list.choose();
                if (contact != null) {
                    String emailId = "";

                    for (int i = 0; i < contact.countValues(Contact.EMAIL); i++) {
                        emailId = contact.getString(Contact.EMAIL, i);
                        System.out.println("_ _ _  _ __  EMAIL : " + i + " " +  emailId);
                    }
                }
            } catch (PIMException e) {
                Dialog.inform("Proble creating contact list!");
                e.printStackTrace();
            }

在函数下方找到只返回包含电子邮件地址的联系人列表：

/*import email id from the contact list. */

public Vector getEmail()
{

    Vector emailList=new Vector();//contains the list of contact
    email_list.removeAllElements();
    try
    {
        PIM pim = PIM.getInstance();
        ContactList contacts;
        contacts = (ContactList) pim.openPIMList(PIM.CONTACT_LIST, PIM.READ_ONLY);
        Enumeration items;
        items = contacts.items();

        while(items.hasMoreElements())
        {
            Contact contact = (Contact) items.nextElement();

            String emailID = "";
            if (contacts.isSupportedField(Contact.EMAIL) && (contact.countValues(Contact.EMAIL) > 0) ) 
            {   
                 emailID=contact.getString(Contact.EMAIL, 0);

                //emailList.addElement(arr);
            }
            String firstName = "";
            if ((contacts.isSupportedField(Contact.NAME)) && (contact.countValues(Contact.NAME) > 0))
            {
                String[] name = contact.getStringArray(Contact.NAME, 0);
                firstName = name[Contact.NAME_GIVEN];
              //  String lastName = name[Contact.NAME_FAMILY];
            }
            String arr[]={emailID,firstName};//array which contains emailid and first name
            emailList.addElement(arr);

        }
    }
    catch(Exception pe)
    {
    }
    return emailList;
}
