Answer 1

try { 
      //set the download URL, a url that points to a file on the internet 
      //this is the file to be downloaded 
      URL url = new URL("http://IP/Downloads/data.xml"); 

      //create the new connection 
      HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 



      //and connect! 
      urlConnection.connect(); 

      //set the path where we want to save the file 
      //in this case, going to save it on the root directory of the 
      //sd card. 
      File SDCardRoot = Environment.getExternalStorageDirectory(); 
      //create a new file, specifying the path, and the filename 
      //which we want to save the file as. 
      File file = new File(SDCardRoot,"data.xml"); 

      //this will be used to write the downloaded data into the file we created 
      FileOutputStream fileOutput = new FileOutputStream(file); 

      //this will be used in reading the data from the internet 
      InputStream inputStream = urlConnection.getInputStream(); 

      //this is the total size of the file 
      int totalSize = urlConnection.getContentLength(); 
      progressDialog.setMax(totalSize); 

      //variable to store total downloaded bytes 
      int downloadedSize = 0; 

      //create a buffer... 
      byte[] buffer = new byte[1024]; 
      int bufferLength = 0; //used to store a temporary size of the buffer 

      //now, read through the input buffer and write the contents to the file 
      while ((bufferLength = inputStream.read(buffer)) > 0) { 
        //add the data in the buffer to the file in the file output stream (the file on the sd card 
        fileOutput.write(buffer, 0, bufferLength); 
        //add up the size so we know how much is downloaded 
        downloadedSize += bufferLength; 

      } 
      //close the output stream when done 
      fileOutput.close(); 
      //catch some possible errors... 
    } catch (MalformedURLException e) { 
      e.printStackTrace(); 
    } catch (IOException e) { 
      e.printStackTrace(); 
    }

Si vous essayez de définir la mise en page ou dessinable ou le style par XML distant, vous ne pouvez pas.

meilleure façon de le lire dans la chaîne et faire tout ce que vous voulez faire. Public String getXmlFromUrl (String url) {
Chaîne xml = null;

try 
{ 
    //default http client 
    HttpClient httpClient = new DefaultHttpClient(); 

    HttpPost httpPost = new HttpPost(url); 

    System.out.println("URL IN PARSER:==="+url+"===="); 

    HttpResponse httpResponse = httpClient.execute(httpPost); 

    HttpEntity httpentity = httpResponse.getEntity(); 

    xml = EntityUtils.toString(httpentity); // I have changed it... because  occur while downloading.. 

    Log.d("response", xml); 
} 
catch(UnsupportedEncodingException e) 
{ 
    e.printStackTrace(); 
} 
catch (ClientProtocolException e) 
{ 
    e.printStackTrace(); 
} 
catch (IOException e) 
{ 
    e.printStackTrace(); 
} 


return xml; 

}
