Android: 联系人列表有重名

Question

我有一个按排序顺序排列的联系人列表。但在我的联系人列表中，该名称与相同的号码重复。我认为问题是因为联系人列表与不同帐户同步。

我用哈希图检查。但是当我使用哈希映射时，结果没有按名称排序。

private static final String[] PROJECTION = new String[] {
    ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
    ContactsContract.Contacts.DISPLAY_NAME,
    ContactsContract.CommonDataKinds.Phone.NUMBER
};

ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION,
  null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");

if (cursor != null) {
    try {
        int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
        String nameContact = cursor.getString(nameIndex);
    finally {
        cursor.close();
    }
}

适配器

holder.name.setText(itemListPogo.get(position).getItemName());

任何人都可以帮助避免名称重复。

我会推荐你使用我搜索结束的地方，它会给你最快的结果。

public static List<ContactDTO> getPhone(Context context) {
    List<ContactDTO> contactList = new ArrayList<ContactDTO>();
    ContentResolver cr = context.getContentResolver(); 
    String[] PROJECTION = new String[] { 
        ContactsContract.RawContacts._ID, 
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Phone.PHOTO_URI,
        ContactsContract.CommonDataKinds.Phone.NUMBER,
        ContactsContract.CommonDataKinds.Photo.CONTACT_ID };

    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    String filter = ""+ ContactsContract.Contacts.HAS_PHONE_NUMBER + " > 0 and " + Phone.TYPE +"=" + Phone.TYPE_MOBILE;     
    String order = ContactsContract.Contacts.DISPLAY_NAME + " ASC";// LIMIT " + limit + " offset " + lastId + "";

    Cursor phoneCur = cr.query(uri, PROJECTION, filter, null, order);
    while(phoneCur.moveToNext()) {
        ContactDTO dto = new ContactDTO();
        dto.setName("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
        dto.setMobileNo("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
        dto.setPhotoUrl("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI)));
        dto.setContactId("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Photo.CONTACT_ID)));
        contactList.add(dto);
    }
    phoneCur.close();

    return contactList;
}

其中 ContactDTO 是简单的 POJO class。

I think the issue is because of the contact list sync with different account.

是的，您的联系人列表同步了很多帐户。您应该过滤帐户类型的联系人：ContactsContract.CommonDataKinds.Phone.ACCOUNT_TYPE_AND_DATA_SET.
您可以研究的帐户： https://developer.android.com/reference/android/accounts/AccountManager.html

Answer 3

您看到重复的联系人，因为他们属于不同的帐户。即如果与 Facebook、WhatsApp 和 Google 帐户同步，相同的号码可以显示 3 次。您可以在此处找到更多信息 Android Account Manager

这就是您如何使用列 ContactsContract.RawContacts.ACCOUNT_TYPE 来过滤和检索仅与单个帐户关联的联系人。

String[] projection = new String[] {
                    ContactsContract.RawContacts._ID,
                    ContactsContract.RawContacts.ACCOUNT_TYPE,
                    ContactsContract.Contacts.DISPLAY_NAME,
                    ContactsContract.CommonDataKinds.Phone.PHOTO_URI,
                    ContactsContract.CommonDataKinds.Phone.NUMBER,
                    ContactsContract.CommonDataKinds.Photo.CONTACT_ID };


            String selectionFields =  ContactsContract.RawContacts.ACCOUNT_TYPE + " = ?";
            String[] selectionArgs = new String[]{"com.google"};

            Cursor cursor =  getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    projection,
                    selectionFields,
                    selectionArgs,
                    ContactsContract.Contacts.DISPLAY_NAME
            );

在此代码中，仅选择了与 Google 帐户关联的联系人。同样，如果您只想获取 WhatsApp 联系人列表，您可以将 "com.google" 替换为 "com.whatsapp"

Answer 4

您可以搜索 aggregated 联系人而不是所有 RawContact。这将只为您提供 1 个具有给定名称的联系人（如在“联系人”应用程序中）。示例（更改您的代码）：

private static final String[] PROJECTION = new String[] {
    ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
    ContactsContract.Contacts.DISPLAY_NAME_PRIMARY, // Honeycomb+ should use this
    ContactsContract.CommonDataKinds.Phone.NUMBER
};

ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(
    ContactsContract.Contacts.CONTENT_URI, 
    PROJECTION, 
    null, 
    null, 
    ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + " COLLATE NOCASE ASC");

if (cursor != null) {
    try {
        int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME_PRIMARY);
        String nameContact = cursor.getString(nameIndex);
    finally {
        cursor.close();
    }
}
