Php Android-通过Http获取json数据并列出它们

我需要从服务器上生成的json中获取数据

目前，my json生成以下矩阵：

{"success":1,"message":[{"pedidos_id":"1","pedidos_nome":"Teste","pedidos_email":"ygormagrii@gmail.com"},{"pedidos_id":"19","pedidos_nome":"5","pedidos_email":"camiseta"},{"pedidos_id":"75","pedidos_nome":"6","pedidos_email":"hdj"},{"pedidos_id":"76","pedidos_nome":"5","pedidos_email":"grhd"},{"pedidos_id":"77","pedidos_nome":"5","pedidos_email":"gdf"}]}

生成此JSON PHP的代码如下所示：

    $user_id=$_REQUEST['user_id'];

$r=mysql_query("select * from tbl_storefinder_pedidos where user_id='$user_id'",$con);

$response= array();
$info=array();
$flag = array();

if( mysql_num_rows( $r ) > 0 ) {
    while($row = mysql_fetch_array($r))
    {
        $flag[pedidos_id]=$row[pedidos_id];
        $flag[pedidos_nome]=$row[pedidos_nome];
        $flag[pedidos_email]=$row[pedidos_email];
        array_push($info, $flag);
    }
        $response["success"] = 1;
        $response["message"] = $info;
        echo json_encode($response);
}
else
{
        $response["success"] = 0;
        $response["message"] = "No entries yet";
        echo json_encode($response);
}
mysql_close($con);

我的活动接收json并试图限制它：
