我想在Spinner外部点击后关闭一个Android微调器.这甚至可能吗？

我已经阅读了许多关于PHP和JSONArray循环的其他问题.我正在通过我的Android设备向他们的班级和studentId发送不同学生的JSONArray值.使用这些值,我在数据库中搜索它们的名称并返回一个JSONArray.

JSON Input: [{"studentId":"2","class":"2a","dbname":"testDb"}]
<?php

 $jsonString = $_POST['json'];  //see comment below

 $jArray = json_decode($jsonString, true);

 $conn = mysql_connect('localhost', 'user', 'pwd' );

mysql_select_db('dbname', $conn);

foreach( $jArray as $obj ){
    $className = $obj['class'];   //String
    $id= $obj['studentId'];       //int

    $result = mysql_query("SELECT name FROM student WHERE class='$className' AND id='$id'");

    $e=mysql_fetch_assoc($result);    //will only fetch 1 row of result
    $output[]=$e;


}

      echo (json_encode($output));

?>

 List<NameValuePair> nVP = new ArrayList<NameValuePair>(2);  
 nVP.add(new BasicNameValuePair("json", studentJson.toString())); …
