我目前正在官员姓名，但我想添加参考，但我不知道我是否正确执行了该程序以及如何在android上获取参考值？目前我在应用程序活动开始时敬酒官员姓名。我想添加对吐司的引用，但我不知道如何获得它的价值。
php脚本
<?php
require "init.php";
$user_name = $_POST["user_name"];
$password = $_POST["password"];
$activate;
$sql = "select officer_name,reference from user_tbl where user_name like '" . $user_name . "' and password like '" . $password . "' and activate = 1;";
$result = mysqli_query($con, $sql);
$response = array();
if (mysqli_num_rows($result) > 0) {
$row = mysqli_fetch_row($result);
$officer_name = $row[0];
$reference = $row[1];
$code = "Login_Success";
array_push($response, array("code" => $code,
"officer_name" => $officer_name,
"reference" => $reference));
echo json_encode($response);
} else {
$code = "Login_Failed";
$message = "Error! User not found or Not Activated";
array_push($response, array("code" => $code, "message" => $message));
echo json_encode($response);
}
mysqli_close($con);
?>
安卓代码
StringRequest stringRequest = new StringRequest(Request.Method.POST, loginUrl,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONArray jsonArray = new JSONArray(response);
JSONObject jsonObject = jsonArray.getJSONObject(0);
String code = jsonObject.getString("code");
if (code.equals("Login_Failed"))
{
builder.setTitle("Login Error");
displayAlert(jsonObject.getString("message"));
}
else
{
Intent intent = new Intent(Login.this,MainActivity.class);
Bundle bundle = new Bundle();
bundle.putString("officer_name", jsonObject.getString("officer_name"));
intent.putExtras(bundle);
startActivity(intent);

使用 jsonObject.getString 方法，例如<modelVersion>4.0.0</modelVersion>
