如何通过id / lookupkey检索单个联系人和一些相关数据(例如电子邮件,电话号码,地址......)?

这是我用来添加联系人的代码(实际上是来自互联网,对我有用)。

// Asking the Contact provider to create a new contact
    try {
        result = this.context.getContentResolver().applyBatch(
                ContactsContract.AUTHORITY, ops);
    } catch (Exception e) {
        e.printStackTrace();
        Toast.makeText(this.context, "Exception: " + e.getMessage(),
                Toast.LENGTH_SHORT).show();
    }

    Uri myContactUri = result[0].uri;
    int lastSlash = myContactUri.toString().lastIndexOf("/");
    int length = myContactUri.toString().length();
    int contactID = Integer.parseInt((String) myContactUri.toString()
            .subSequence(lastSlash + 1, length));

    return contactID;

现在我想要获取这个新联系人。我该怎么做?我想出的就是:

    ContentResolver content = context.getContentResolver();

    String[] projection = { Data.LOOKUP_KEY, Data.MIMETYPE,
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Email.ADDRESS };

    // Defines the selection clause
    String selection = Data.LOOKUP_KEY + " = ?";

    // Defines the sort order
    String sortOrder = Data.LOOKUP_KEY;

    String[] args = {"2400"};

    Cursor cursor = content.query(Data.CONTENT_URI, projection, selection,
            args, sortOrder);

当我删除选择时,我会获得所有联系人+所有数据。所以我在我的情况下查找了密钥2400,并希望通过其lookupkey获取此联系人。好吧,不行。 cursor.getCount()返回0。

有什么想法吗?

我现在的解决方案是使用以下内容:

    String[] projection = { Data.MIMETYPE,
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER,
            ContactsContract.CommonDataKinds.Email.ADDRESS };

    // Defines the selection clause
    String selection = ContactsContract.Data.RAW_CONTACT_ID + "=?";

    // Defines the sort order
    String sortOrder = Data.LOOKUP_KEY;

    String[] args = { id+"" };

    Cursor cursor = content.query(Data.CONTENT_URI, projection, selection,
            args, sortOrder);

排序顺序并不重要,但我使用RAW CONTACT ID,效果很好!
