如何将两个值API传递给android？

Question

我想使用php从数据库中选择两个值，然后将其传递给android。

我想在AutoCompleteTextView中使用这些值。

当我选择一个字段时，它将在AutoCompleteTextView上显示该字段并将Id存储在后台。

这是我的完整代码： -

            return null;
        }

    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;

    }
}

这是我的API

 <?php

include("connection.php");

    $response = array();
    //$id = $_REQUEST["wt_wod_code"];
    //$uid=$id;


    $result = mysql_query("SELECT DISTINCT cl_wodcode,cl_pname FROM clients") or die(mysql_error());
    $count = mysql_num_rows($result);

    // check for empty result
    if ($count > 0) {
        // looping through all results
        // products node
        $response["visit"] = array();

        while ($row = mysql_fetch_array($result))
        {


            $Ordera = array();

            $visit["cl_wodcode"] = $row["cl_wodcode"];
            $visit["cl_pname"] = $row["cl_pname"];


            $response["success"]=1;


            // push single product into final response array
            array_push($response["visit"], $visit);
        }


            $response["success4"] = 1;
        // echoing JSON response
        echo json_encode($response);


    }

    else 
    {
        // no products found
        $response["success"] = 0;
        $response["message"] = "No picture found";

        // echo no users JSON
        echo json_encode($response);
    }


?>

请建议我如何传递两个值？

Answer 1

它显示了什么样的错误？ 可以 ？ 您从JSON解析的值（cl_pname和amp; cl_wodcode）是否都是字符串？
