Android: (webservices) 如何在远程服务器中存储数据并检索它

Question

我有一个 Android 应用程序需要用户名和密码才能登录。我需要将用户名和密码保存在远程服务器中，方法是在注册页面中输入详细信息，并在警告框中显示 Registered successfully。当用户下次打开应用程序时，他将登录。我想使用客户端/服务器机制。收到响应后，我想使用 sax 解析器或 soap 对其进行解析。我通过谷歌搜索了很多，但没有找到正确的例子。由于我是网络服务的新手，我无法解决它。请帮助我。

EditText input1 = (EditText) findViewById(R.id.usertext);
EditText input2 = (EditText) findViewById(R.id.Passtext);
String username = input1.getText().toString();
String password = input2.getText().toString();
