Question

I have just started to develop android application yesterday and having a great fun with that technology.

I need to create an application in which user needs to enter the city name in edittext and then the current temperature of that city is shown in the textview.

I want to use the following URL for that where i can easily add the city name.
Currently here i am passing sydney.

Please help me regarding this.

Using SAX Parser you can do the following.

/* Replace blanks with HTML-Equivalent. */
//url = new URL(queryString.replace(” “, “%20”));

                     /* Get a SAXParser from the SAXPArserFactory. */
                     SAXParserFactory spf = SAXParserFactory.newInstance();
                     SAXParser sp = spf.newSAXParser();

                     /* Get the XMLReader of the SAXParser we created. */
                     XMLReader xr = sp.getXMLReader();

                     /*
                      * Create a new ContentHandler and apply it to the
                      * XML-Reader
                      */
                     GoogleWeatherHandler gwh = new GoogleWeatherHandler();
                     xr.setContentHandler(gwh);

                     /* Use HTTPClient to deal with the URL */ 
                     HttpClient httpclient = new DefaultHttpClient(); 
                     HttpGet httpget = new HttpGet(queryString.replace(" ", "%20")); 
                     Log.d(DEBUG_TAG, "executing request " + httpget.getURI()); 
                     // create a response handler 
                     ResponseHandler<String> responseHandler = new BasicResponseHandler();
                     Log.i("Respond Handler","Step 1");
                     String responseBody = httpclient.execute(httpget, responseHandler); 
                      Log.d(DEBUG_TAG, "response from httpclient:\n "+responseBody); 

                     ByteArrayInputStream is = new ByteArrayInputStream(responseBody.getBytes()); 
                     xr.parse(new InputSource(is)); 
                     Log.d(DEBUG_TAG, "parse complete"); 
                     // parse complete
