Problema nello "scaricamento/caricamento" dei dati di un data base on line

[Gorillaz]

Ho un problema con il mio progetto, ho il mio database on line su altervista già riempito e salvato. Ma quando cerco di recuperare i dati e di andarli ad inserire nella listview carica solo il primo elemento della tabella e gli ultimi due. Inoltre quando cercherà di caricare l'altra riga della tabella anche qui non riesce a ricarla. La tabella è questa:

e questo è il suo contenuto:

utilizzo questo script php per caricarla:

<?php
        $host='localhost';
        $uname='root';   //Username per accedere nel database
        $pwd='';   //Password del database
        $db="my_notizieappandroid";   //Nome del database
        $select=$_REQUEST['id'];
        $con = mysql_connect($host,$uname,$pwd) or die("connection failed");
        mysql_select_db($db,$con) or die("db selection failed");
        $r=mysql_query($select,$con);
        while($row=mysql_fetch_array($r)){
                $flag[]=$row;
        }
        print(json_encode($flag));
        mysql_close($con);
?>

ed il codice java. Costanti.java

public class Costanti {
    private static String UrlLink = "http://www.myapp.altervista.org/";
    private static String PHPShow = "visualizza.php";
    private static String TABLE_NOTIZIE = "news";
    private static String KAY_ID = "ID";
    private static String KAY_TITLE = "title";

    private static String KAY_BODY = "body";
    private static String KAY_SOURCE = "source";
    private static String KAY_DATE = "date";

    public static String getPHPShow() {
        return PHPShow;
    }

    public static String getKayDate() { return  KAY_DATE; }

    public static String getKaySource() { return KAY_SOURCE; }

    public static String getKayBody() { return KAY_BODY; }

    public static String getKayDescription() { return KAY_DESCRIPTION; }

    public static String getKayTitle() { return KAY_TITLE; }

    public static String getKayID() { return KAY_ID; }

    public static String getTableNotizie() { return TABLE_NOTIZIE; }

    public static String getUrlLink() { return UrlLink; }

E questo diciamo è l'output che ho quando vado a testare la mia applicazione sul mio cellulare:
