我的Android代码没有响应，Toast也没有调用按钮单击一些我帮助我请…您通过POST将参数从Android发送到PHP，在PHP中尝试通过GET接收参数 首先，尝试在PHP中更改接收方法，从GET到POST：
<?php
header("Content-Type:application/json");
include("function.php");
if(!empty($_POST['name']) && !empty($_POST['id']) && !empty($_POST['pass']))
{
$name = $_POST['name'];
$id = $_POST['id'];
$pass = $_POST['pass'];
...
