Android Webview POST

Question

I am trying to accomplish something quite simple, yet I have found no good documentation on this. I have a webView, and I need to load a page in it that requires POST data. Seems like a simple process, yet I cannot find a way to display the result in a webView.

The process should be simple:

query(with POST data) -> webserver -> HTML response -> WebView.

I can submit data using a DefaultHttpClient, but this cannot be displayed in a WebView.

Any suggestions?

Much Thanks

Solution

private static final String URL_STRING = "http://www.yoursite.com/postreceiver";

    public void postData() throws IOException, ClientProtocolException {  

         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
         nameValuePairs.add(new BasicNameValuePair("foo", "12345"));  
         nameValuePairs.add(new BasicNameValuePair("bar", "23456"));

         HttpClient httpclient = new DefaultHttpClient();  
         HttpPost httppost = new HttpPost(URL_STRING);  
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

         HttpResponse response = httpclient.execute(httppost);  
         String data = new BasicResponseHandler().handleResponse(response);
         mWebView.loadData(data, "text/html", "utf-8");
    }

Answer 1

If you use a WebView from the start could it work?

A Webview with a html/js that does the POST, and naturally displays the result.

Answer 2

Try this:

private static final String URL_STRING = "http://www.yoursite.com/postreceiver";

public void postData() throws IOException, ClientProtocolException {  

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
     nameValuePairs.add(new BasicNameValuePair("foo", "12345"));  
     nameValuePairs.add(new BasicNameValuePair("bar", "23456"));

     HttpClient httpclient = new DefaultHttpClient();  
     HttpPost httppost = new HttpPost(URL_STRING);  
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

     HttpResponse response = httpclient.execute(httppost);  

}

I would recommend doing this as part of an AsyncTask and updating the WebView afterwards
