Question

我正在尝试提取联系人列表并附加与给定人员相关联的所有联系人。我遇到的问题是我的查询返回所有已通过电子邮件发送的联系人。我不想包括我通过电子邮件发送的所有联系人，但我只想要主要的联系人（比如内置的People应用程序中显示的内容）。

在下面的代码中，我试图通过使用ContactsContract.Contacts.CONTENT_URI查询限制返回的电子邮件来限制电子邮件，但这似乎不起作用。

非常感谢任何帮助。

private ArrayList<ContactFriend> allContacts;
private Cursor contactsCursor;
private Cursor emailCursor;

void load() {
    getLoaderManager().initLoader(CONTACTS_LOADER_ID, null, this);
    getLoaderManager().initLoader(EMAILS_LOADER_ID, null, this);
}

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    if (id == CONTACTS_LOADER_ID) {
        String[] projection = {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME_PRIMARY,
                ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,
        };
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + " ASC";
        return new CursorLoader(getActivity(),
                ContactsContract.Contacts.CONTENT_URI,
                projection,
                null,
                null,
                    sortOrder);
    } else if (id == EMAILS_LOADER_ID) {
        String[] projection = {
                ContactsContract.CommonDataKinds.Email.DATA,
                ContactsContract.CommonDataKinds.Email.CONTACT_ID
        };
        String sortOrder =
                ContactsContract.CommonDataKinds.Email.CONTACT_ID + ", " +
                        ContactsContract.CommonDataKinds.Email.DATA + " ASC";
        return new CursorLoader(getActivity(),
                            ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                            projection,
                            null,
                            null,
                            sortOrder);
    } else {
        // should never happen
        return null;
    }
}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    int id = loader.getId();
    if (id == CONTACTS_LOADER_ID) {
        contactsCursor = cursor;
    } else if (id == EMAILS_LOADER_ID) {
        emailCursor = cursor;
    }

    if (contactsCursor != null && emailCursor != null) {
        init();
    }
}

void init() {
    if (allContacts == null) {
        allContacts = getAllContacts();
    }
    // do stuff with allContacts
}

private ArrayList<ContactFriend> getAllContacts() {
    HashMap<Integer, ArrayList<String>> emails = getEmailMap();
    ArrayList<ContactFriend> result = new ArrayList<ContactFriend>();

    contactsCursor.moveToFirst();
    do {
        String name = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME_PRIMARY));
        String photo = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
        int id = contactsCursor.getInt(contactsCursor.getColumnIndex(ContactsContract.Contacts._ID));
        ArrayList<String> contactEmails = emails.get(id);
        if (!contactEmails.isEmpty()) {
            result.add(new ContactFriend(name, contactEmails, photo, id));
        }
    } while (contactsCursor.moveToNext());
    return result;
}

private HashMap<Integer, ArrayList<String>> getEmailMap() {
    HashMap<Integer, ArrayList<String>> result = new HashMap<Integer, ArrayList<String>>();

    while (contactsCursor.moveToNext()) {
        int id = contactsCursor.getInt(contactsCursor.getColumnIndex(ContactsContract.Contacts._ID));
        result.put(id, new ArrayList<String>());
    }

    Set<Integer> contactIds = result.keySet();
    while (emailCursor.moveToNext()) {
        int id = emailCursor.getInt(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID));
        if (contactIds.contains(id)) {
            String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
            result.get(id).add(email);
        }
    }
    return result;
}

添加此项以防其他人遇到同样的问题。将ContactsContract.Contacts.IN_VISIBLE_GROUP添加到投影中，然后仅选择那些值等于1的条目，这样我就能找到我想要的东西。
