我目前正在运行一个PHP脚本，该脚本从我的数据库中返回数据。

下面是我的php脚本，其中注释了一些信息。正如你所看到的，我正在将dietid硬编码为=1。当脚本运行时，我想将活动中的营养师传递到脚本中。我所有的代码都工作正常，数据显示在我的列表视图中，我如何传递dietid？

提前感谢

从使用dietid更新的数据库获取数据的脚本

$con = mysqli_connect($host, $user, $pwd, $db);

 if(mysqli_connect_errno($con)) {
 die("Failed to connect to MySQL: " . mysqli_connect_error());
  } 

   $dietid = array( $_GET['dietid'] );
   $sql = "SELECT * FROM food WHERE dietid =".$dietid;
   $result = mysqli_query($con, $sql);

   $rows = array();

  while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
   $rows[] = $row; 
   }

   mysqli_close($con);
   echo json_encode($rows);

用新URL更新的分段主活动

  private void initView() {
    // show progress dialog
    dialog = ProgressDialog.show(this, "", "Loading...");
    int dietid = 1;
    String url = "http://xxxxxxxxxxx/diet_info.php?dietid="+dietid;
    FetchDietInformationTask task = new FetchDietInformationTask(this);
//    List<NameValuePair> params = new ArrayList<NameValuePair>();
 //   params.add(new BasicNameValuePair("dietid","1"));
    task.execute(url);
}
  public void onFetchComplete(List<FoodInfoModel> data) {
    // dismiss the progress dialog
    this.data = data;
    System.out.println("data is " + data);
    if(dialog != null)  dialog.dismiss();
    // create new adapter
     adapter = new DietAdapterNew(this, data);
    // set the adapter to list
    listview.setAdapter(adapter);
    adapter.notifyDataSetChanged();
   // listview.setOnItemClickListener(myOnItemClickListener);
    }

public void onFetchFailure(String msg) {
    // dismiss the progress dialog
    if(dialog != null)  dialog.dismiss();
    Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
}
