android 如何将电话簿SDN数字和其他普通的数字混合在一起？

最初的设计将默认SDN单独分出来，副标题"SDN"。
下面的变化可以通过例如实现SDN并安排普通相同数量在一起，按字母顺序排列。

DefaultContactListAdapter.java 的 configureSelection() 方法中
对 selection 为 IS_SDN_CONTACT + " < 1" 的例如以下语句注解掉（总共同拥有五处）：
/**
* M: New Feature SDN <br>
* Origin code: <br>
* private void configureSelection(<br>
* @{
*/
protected void configureSelection(
CursorLoader loader, long directoryId, ContactListFilter filter) {
if (filter == null) {
return;
}
if (directoryId != Directory.DEFAULT) {
return;
}
StringBuilder selection = new StringBuilder();
List<String> selectionArgs = new ArrayList<String>();
switch (filter.filterType) {
case ContactListFilter.FILTER_TYPE_ALL_ACCOUNTS: {
// We have already added directory=0 to the URI, which takes care of this
// filter
/** M: New Feature SDN @{ */
// 1 selection.append(RawContacts.IS_SDN_CONTACT + " < 1");
selection.append(RawContacts.IS_SDN_CONTACT + " < 2");
/** @} */
break;
}
case ContactListFilter.FILTER_TYPE_SINGLE_CONTACT: {
// We have already added the lookup key to the URI, which takes care of this
// filter
break;
}
case ContactListFilter.FILTER_TYPE_STARRED: {
selection.append(Contacts.STARRED + "!=0");
break;
}
case ContactListFilter.FILTER_TYPE_WITH_PHONE_NUMBERS_ONLY: {
selection.append(Contacts.HAS_PHONE_NUMBER + "=1");
/** M: New Feature SDN @{ */
// 2 selection.append(" AND " + RawContacts.IS_SDN_CONTACT + " < 1");
/** @} */
break;
}
case ContactListFilter.FILTER_TYPE_CUSTOM: {
selection.append(Contacts.IN_VISIBLE_GROUP + "=1");
if (isCustomFilterForPhoneNumbersOnly()) {
selection.append(" AND " + Contacts.HAS_PHONE_NUMBER + "=1");
}
/** M: New Feature SDN @{ */
// 3 selection.append(" AND " + RawContacts.IS_SDN_CONTACT + " < 1");
/** @} */
break;
}
case ContactListFilter.FILTER_TYPE_ACCOUNT: {
// We use query parameters for account filter, so no selection to add here.
/** M: Change Feature: As Local Phone account contains null account and Phone
* Account, the Account Query Parameter could not meet this requirement. So,
* We should keep to query contacts with selection. @{ */
if (AccountType.ACCOUNT_TYPE_LOCAL_PHONE.equals(filter.accountType)) {
selection.append("EXISTS ("
