Question

我正在尝试使用get请求在Android上实现用户注册。它需要一个电子邮件和密码。所以它不起作用，没有任何东西被发送到服务器。感谢那些试图帮助我的人。

Answer 1

问题是您正在尝试在主线程中进行联网，从而捕获NetworkOnMainThreadException。在android中进行网络连接时，需要在单独的线程中进行。

<强>溶液

Asynctask是最好的解决方案。您可以click here获取有关Asynctask的更多信息。将所有网络内容放在AsyncTask的doInBackground()方法中，因为它在一个单独的线程上运行。

Answer 2

您可以将onClick代码移至自定义异步类。检查下面的示例

   class CustomAsync extends AsyncTask<Void, Void, Void>{

        protected doBackground(String... URL){
                        HttpClient Client = new DefaultHttpClient();
                       try{
                        String SetServerString = "";
                        HttpGet httpget = new HttpGet(URL[0]);
                        ResponseHandler<String> responseHandler = new BasicResponseHandler();
                        SetServerString = Client.execute(httpget, responseHandler);

         }catch(Exception e){}
        }

        protected void onPostExecute(Long result) {
        }

使用新的CustomAsync（）调用。执行（＆＃34; http://sadakafund.com/api/add_user.php?name=＆＃34; + loginValue +＆＃34;＆amp; surname =＆＃34; + fnameValue +＆＃34;＆amp; email =＆＃34 + + emailValue＆＃34;＆安培;密码=＆＃34 + passValue＆＃34）;

Android系统。使用get请求注册
