如何使用Android EditText Data填充在线XML

Question

I currently have an app that shows a listview of data that it gets from the internet.

Similar to the tutorial Here I am using a HTML file, and a webview right now, in order to add new data to the online XML. Like this:

<div id="stylized" class="myform">

<form action="http:site.com/test/update.php" method="GET">

    <label>Name
        <span class="small">Name of Event</span>
    </label>
<input type="text" name="title">

Now, anytime I fill in the above field "title" gets updated online by my .php script. That works flawlessly, with multiple fields.

I just want to know how I can get rid of the tacky webview. I created a custom form using editText, layouts, and buttons. But how can I use the new form to update the online XML. What is the best way to grab the data out of the editText and pass it to the <form action="http:site.com/test/update.php" method="GET"> file?

Thanks

You can use Android's built-in Http client to send a GET request to your server.

1. Retrieve data from EditText and process it with URLEncoder it to prepare GET request:

   String getUrl = "http://example.com/test/update.php?data=" + URLEncoder.encode(editText.getText().toString(), "UTF-8");
   

2. Make an Http GET request using HttpURLConnection Android Http client:

   URL url = new URL(getUrl);
   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
   

3. Read server response.

   InputStream is = urlConnection.getInputStream();
   StringBuilder response = new StringBuilder();
   byte[] buffer = new byte[1024];
   int len = -1;
   while ((len = is.read(buffer)) != -1)
       s.append(new String(buffer, "UTF-8"));
   is.close();
   

4. Close connection:

   urlConnection.disconnect();
