Java ANDROID：使用LAZYLIST从PHP JSON过滤Listview数据

我目前正在开发一个移动订购应用程序，我使用的是来自的listview来汇总我的订单，但我的问题是，我的数据库（Mysql）中的所有订单数据都显示出来了

我只想显示每个客户ID的订单

还有PHP代码

    <?php
mysql_connect('localhost','root','')or die ('No Connection');
mysql_select_db('dbmoms');

//$o_od  = $_GET['text_ordernumber'];

$sql ="SELECT * FROM orders"; // WHERE ord_num ='$o_od' ";  //WHERE ord_num = '$ordnum'
$result = mysql_query($sql);
while($row = mysql_fetch_assoc($result)){
    $arr['orders'][]= $row;
    
}
$json = json_encode($arr);

$json_encoded_string = json_encode($arr); 
 $json_encoded_string = str_replace("\\/", '/', $json_encoded_string);

echo $json_encoded_string;

    ?>

我不确定我是否完全理解您的要求-您从数据库中提取了一些行，对吗？然后“我想通过在订单摘要中获取客户id（文本视图中显示的客户id）来过滤这些数据”——我不知道该怎么做。你能试着把它换成一个问题吗？好的，我试着做一些屏幕截图，把我的问题换成另一个问题，，
    <?php
mysql_connect('localhost','root','')or die ('No Connection');
mysql_select_db('dbmoms');

//$o_od  = $_GET['text_ordernumber'];

$sql ="SELECT * FROM orders"; // WHERE ord_num ='$o_od' ";  //WHERE ord_num = '$ordnum'
$result = mysql_query($sql);
while($row = mysql_fetch_assoc($result)){
    $arr['orders'][]= $row;
    
}
$json = json_encode($arr);
