Android Webview POST

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");
    }

You can also pass post key:value pair in JSON format to web view.

String userName = "admin";
String password = "Admin@2021"; 
    JSONObject jsonObject = new JSONObject();
        try {
            jsonObject.put("userName", userName);
            jsonObject.put("password", password);
        } catch (JSONException e) {
            e.printStackTrace();
        }

String url = "http://www.example.com";
webView.postUrl(url, jsonObject.toString().getBytes());
