Android游标返回空联系人

Question

我需要获得至少拥有电话号码的所有联系人。 Android联系人可以从许多帐户中挑选，例如gmail，skype，vibe等。我制作了我需要的课程以获得我需要的联系人。我的问题是，无论如何，联系人不会拥有至少1个电话号码，只显示他们的姓名和头像。任何人都可以在我的代码中说出我做错了吗？我的代码源在下面分享。

    String selection = ContactsContract.Contacts.DISPLAY_NAME + " LIKE ? OR "
            + ContactsContract.Contacts.DISPLAY_NAME + " LIKE ? OR "
            + ContactsContract.Contacts.DISPLAY_NAME + " LIKE ? AND "
            + ContactsContract.Contacts.HAS_PHONE_NUMBER + "=='1'";

    return new CursorLoader(this,
