Blackberry - 如何从 PIMItem 获取字段标签

Question

我们如何从 PIMItem 获取字段标签。以下代码是 PIMList

String label = pimList.getAttributeLabel(
    blackBerryContact.getAttributes(Contact.TEL, i));

但我有 PIMItem。有一个方法 PIMItem.getPIMList() 在下面的代码中为我返回 null。 API 位于 http://www.blackberry.com/developers/docs /5.0.0api/index.html 表示“getPIMList() 获取与此项目关联的 PIMList。”下面是我试图实现的示例代码 -

// Load the address Book and allow the user to select a contact
BlackBerryContactList contactList = (BlackBerryContactList) 
    PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY);
PIMItem userSelectedContact = contactList.choose();
// Now get the Field labels for contact numbers for userSelectedContact

class Scr extends MainScreen {
    Scr() {

    }

    protected void makeMenu(Menu menu, int instance) {
        super.makeMenu(menu, instance);
        menu.add(new MenuItem("add label", 1, 1){public void run() {
            try {
                BlackBerryContactList contactList = 
                    (BlackBerryContactList) PIM.getInstance().openPIMList(
                    PIM.CONTACT_LIST, PIM.READ_ONLY);
                BlackBerryContact contact = 
                    (BlackBerryContact) contactList.choose();
                    add(new LabelField(getContactInfo(contact)));
            } catch (PIMException e) {
                e.printStackTrace();
            }

        }});
    }

    String getContactInfo(BlackBerryContact c) {
        StringBuffer result = new StringBuffer();
        result.append("Name: ");
        result.append(c.getStringArray(
                BlackBerryContact.NAME, 0)[BlackBerryContact.NAME_GIVEN]);
        result.append(" ");
        result.append(c.getStringArray(
                BlackBerryContact.NAME, 0)[BlackBerryContact.NAME_FAMILY]);
        result.append("Email: ");
        result.append("\n");
        result.append(c.getString(
                BlackBerryContact.EMAIL, BlackBerryContact.ATTR_NONE));
        return result.toString();
    }
}

Answer 2

感谢马克斯的回复。返回 NULL 问题是我的代码有问题，我已经纠正了。我还能够获取字段标签，但循环仅检索联系人名片上的字段。

我正在寻找 Contact.TEL 拥有的所有 8 个标签 -

Int maxAllowed = contactList.maxValues(Contact.TEL); // Gives me 8 

所有 8 个标签可能都没有被用户使用，例如用户可能有 WORK、WORK2、HOME、HOME2 和 MOBILE。其他传真、寻呼机和其他可能未填写，我想获取所有允许的标签并更新空标签的给定号码。
我们如何检查和更新以下内容，

Contact.ATTR_PAGER, Contact.ATTR_FAX, Contact.ATTR_OTHER

如果解释不清楚或需要更多详细信息，请告诉我。

BlackBerryContactList contactList = (BlackBerryContactList) 
    PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_WRITE);
PIMItem pimItem = contactList.choose();
BlackBerryContact blackBerryContact = (BlackBerryContact)pimItem;
PIMList pimList = blackBerryContact.getPIMList();
// To get Labels 
int phoneCount = blackBerryContact.countValues(BlackBerryContact.TEL);
String[] phoneNumbers = new String[phoneCount];
String[] labels = new String[phoneCount];
for (int i = 0; i > phoneCount; i++) {
    String phoneNumber = blackBerryContact.getString(Contact.TEL, i);
    String label = pimList.getAttributeLabel(
        blackBerryContact.getAttributes(Contact.TEL, i));
//Add the number and label to the array.
    phoneNumbers[i] = phoneNumber;
    labels[i] = label + ":" + phoneNumber;
}
