I’d suggest you take a look at ASyncTask class (available since Android 1.5).
It simplifies the process of creating a background Thread that synchronizes with the GUI thread once it’s complete.
You should be able to achieve what you’re trying using code something list this
private class DownloadFilesTask extends AsyncTask<String, List<Product>, Integer> {
protected List<Products> doInBackground(String... requestStrings) {
int count = requestStrings.length;
int results = 0;
for (int i = 0; i < count; i++) {
String requestString = requestStrings[i];
HttpGet httpGet = new HttpGet(requestString);
httpGet.addHeader("Accept", "text/xml");
String encodingString = "testuser:testpass";
String sEncodedString = Base64Coder.encodeString(encodingString);
try{
String sContent = fetchURL(requestString, sEncodedString);
XMLParser xmlParser = new XMLParser();
List <Product> products = xmlParser.getProducts(sContent);
results++;
publishProgress(products);
}
catch(Exception ex){
Log.e(TAG, ex.getMessage());
}
}
return results;
}
protected void onProgressUpdate(Integer... progress) {
// TODO You are on the GUI thread, and the first element in
// the progress parameter contains the last progress
// published from doInBackground, so update your GUI
}
protected void onPostExecute(int result) {
// Processing is complete, result contains the number of
// results you processed
}
}
And execute by calling
new DownloadFilesTask().execute(url1, url2, url3);
