android - 过滤掉没有电话号码的联系人

Question

我正在尝试从电话中获取联系电话，这是我的查询，但问题是我得到的联系人姓名很少，根本没有电话号码。谁能告诉我如何过滤掉没有联系电话的联系人？

Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] {
    ContactsContract.Contacts._ID,       
    ContactsContract.Contacts.DISPLAY_NAME,
    ContactsContract.Contacts.PHOTO_ID

    };
String selection = 
    ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" +1+"'";

String sortOrder =  ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC";

Answer 1

String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" +1+"' AND "
                   ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '" +1+"'";
