未能使用ContentProviderOperation删除整个联系人 [英] Failure to delete entire contact using ContentProviderOperation

问题描述

我一直在与Android的联系。我可以向他们展示，但更新
当我要删除的，它并没有完全删除。在联系人
应用被示出为（未知）而没有任何数据。这是我的例子：

I have been working with Android contacts. I am able to show them, update but when I want to delete any, it is not deleted completely. In Contacts application is shown as (Unknown) without any data. Here is my example:

ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
.withSelection(Data.CONTACT_ID + "=?", new String[]{selectedid})
.build());
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

我应该做别的事情完全删除联系人？
看来，这些code表ContactsContract.Data删除信息，但我可以做彻底删除联系人不会删除表ContactsContract.Contacts或ContactsContract.RawContacts.how相关的元素？

Should I do anything else to delete contact entirely? It seems that these code delete info in table ContactsContract.Data but it does not delete element related in table ContactsContract.Contacts or ContactsContract.RawContacts.how can i do to delete an contact completely?

=============================================== =============================

============================================================================

另外，我试图去precated方法。它剂量的工作，但我不想这样做。下面是示例code：

also, i tried deprecated method. It dose work, but i do not want to do so. Here is the sample code:

ContentResolver contentResolver = m_cContent.getContentResolver();
contentResolver.delete(People.CONTENT_URI, People.NAME + "=?", new String[] { SelectedName });

如果我修改此code到

and if i modify this code to

ContentResolver contentResolver = m_cContent.getContentResolver();
contentResolver.delete(ContactsContract.Contacts, ContactsContract.Contacts._ID + "=?", new String[] { Selectedid });

有没有任何影响。

这是否意味着人们只能通过删除名称，而不是通过其ID联系人？
在地球上我能做些什么来删除联系人？

Does it mean that one can only delete a contact by name instead of by its id? What on earth can i do to delete contact?

谢谢，

推荐答案

您正试图删除与从数据删除的数据行表。
这是行不通的。

You are trying to delete a contact by deleting its data rows from the Data table. That wouldn't work.

一个接触由几个原始联系人，每个原始姓名已储存在数据表数据。
当删除联系人，所有原材料接点被删除，以及，用自己的数据一起。

A contact is made up of several raw-contacts, each raw-contact has its data saved in the Data table. When deleting a contact, all raw-contacts get deleted as well, along with their data.

做到这一点：

long contactId = 12345;
Uri contactUri = Uri.withAppendedPath(Contacts.CONTENT_URI, String.valueOf(contactId));
int deleted = getContentResolver().delete(contactUri, null, null);

删除将是1，如果操作成功。

deleted will be 1 if the operation succeeded.
