如何使用联系人的lookup_key删除联系人

Question

根据我的阅读，使用 lookup_key 是删除联系人的最佳方式。每个联系人都有一个唯一的查找键，即使联系人已被编辑，而例如按姓名或号码等删除...您可能会删除多个条目。

如果我的电话簿或 SIM 卡中有联系人的查找键：

String thelookupkey = 1393i2f.3789r504-2927292F4D4D2F35274949374B.2537i1272844629.1728i108

如何从我的电话簿中删除此联系人。我知道它类似于下面的内容，但不确定确切的语法（另外，不想在试验时毁掉我的电话簿）

public void deletecontactbutton(View view) {
    context.getContentResolver().delete(ContactsContract.Contacts.CONTENT_LOOKUP_URI,
          null, thelookupkey);

}

我很自豪地说我写了（是的，我！！！）一个子程序，它完全符合我的要求：也就是说，使用 LOOKUP_KEY 删除一个联系人（电话、号码、与该联系人相关的所有详细信息）价值：

public void deletecontactbutton(View view) {

        String thelookupkey;
        thelookupkey = "1885r1471-29373D3D572943292D4333";

//      in our cursor query let's focus on the LOOKUP_KEY column
//      this will give us all the strings in that column
        String [] PROJECTION = new String [] {  ContactsContract.Contacts.LOOKUP_KEY };

//      we're going to query all the LOOKUP_KEY strings ; that is, the unique ids of all our contacts
//      which we can find in the LOOKUP_KEY column of the CONTENT_URI table
        Cursor cur = getContentResolver().query
                (ContactsContract.Contacts.CONTENT_URI, PROJECTION, null, null, null);

        try {
            if (cur.moveToFirst()) {
                do {
                    if
//               If a LOOKUP_KEY value is equal to our look up key string..
                 (cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)).equalsIgnoreCase(thelookupkey)) {
//               then delete that LOOKUP_KEY value, including all associated details, like number, name etc...
                        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, thelookupkey);
                        getContentResolver().delete(uri, null, null);
                    }

                } while (cur.moveToNext());
            }
//      deal with any errors, should they arise
        } catch (Exception e) {
            System.out.println(e.getStackTrace());
        } finally {
//            finally, close the cursor
            cur.close();
        }

    }
