Question

我在J2me上开发了一个应用程序，在诺基亚X2和c2-05上使用。我从数据库访问联系人并记录在内存中，它工作正常，直到我用手机内存写联系人，但现在我想只将联系人写入SIM内存，但事实并非如此。虽然我可以从SIM卡和手机内存中读取但只能写入手机，而SIM卡不允许我，这很奇怪。我的意思是它应该允许读写，或者根本不应该允许读取但不允许写入。感谢

这是我正在使用的代码

private class ContactWriter {

    private ContactList clist;
    public ContactWriter() throws PIMException {
        clist = (ContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST, PIM.WRITE_ONLY, "SIM"); //or I used list[1] in my case its SIM, but still didn't get that!
    }

    public void close() throws PIMException {
        clist.close();
    }

    public void commitContact(ContactDTO contact) throws PIMException {

        Contact c = clist.createContact();
        String name[] = new String[clist.stringArraySize(Contact.NAME)];
        String addr[] = new String[clist.stringArraySize(Contact.ADDR)];

        if (contact.getName() != null) {

            if (clist.isSupportedField(Contact.NAME)) {
                boolean yes = false;
                if (clist.isSupportedArrayElement(Contact.NAME, Contact.NAME_GIVEN)) {
                    name[Contact.NAME_GIVEN] = contact.getName();
                    yes = true;
                } else if (clist.isSupportedArrayElement(Contact.NAME, Contact.NAME_OTHER)) {
                    name[Contact.NAME_OTHER] = contact.getName();
                    yes = true;
                } else if (clist.isSupportedArrayElement(Contact.NAME, Contact.NAME_FAMILY)) {
                    name[Contact.NAME_FAMILY] = contact.getName();
                    yes = true;
                }
                if (yes) {
                    c.addStringArray(Contact.NAME, Contact.ATTR_NONE, name);
                }
            } else if (clist.isSupportedField(Contact.FORMATTED_NAME)) {
                c.addString(Contact.FORMATTED_NAME, Contact.ATTR_NONE, contact.getName());
            }
        }

        if (contact.getAddress() != null) {
            if (clist.isSupportedField(Contact.ADDR)) {
                boolean yes = false;
                if (clist.isSupportedArrayElement(Contact.ADDR, Contact.ADDR_EXTRA)) {
                    addr[Contact.ADDR_EXTRA] = contact.getAddress();
                    yes = true;
                } else if (clist.isSupportedArrayElement(Contact.ADDR, Contact.ADDR_STREET)) {

                c.addString(Contact.FORMATTED_ADDR, Contact.ATTR_NONE, contact.getAddress());
            }
        }

        if (clist.isSupportedField(Contact.TEL)) {
            if ((clist.isSupportedAttribute(Contact.TEL, Contact.ATTR_HOME)) && (contact.getPhoneHome() != null)) {
                c.addString(Contact.TEL, Contact.ATTR_HOME, contact.getPhoneHome());
            }

        c.commit();
    }
}

无法在sim上写联系人。因为sim是由运营商提供的，所以在您编写时可能会出现兼容性问题。这就是为什么j2me不允许在sim上写联系人。

在j2me中将联系人写入SIM卡
