I am trying to implement an app that upon opening, starts to upload the contacts to localhost database (apache), while showing a progress indicator. I want to do this as an asynchronous task.
this is my code so far, and i am feeling abit lost on how to proceed from here.
Main Activity:
public class MainActivity extends Activity{
private ProgressBar pb;
private ProgressDialog progress;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
progress = new ProgressDialog(this);
}
public void open(View view){
progress.setMessage("Downloading Contacts ");
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progress.setIndeterminate(true);
progress.show();
class MyAsyncTask extends AsyncTask<String, Integer, Double>{
@Override
protected Double doInBackground(String... params) {
// TODO Auto-generated method stub
postData(params[0]);
return null;
}
protected void onPostExecute(Double result){
pb.setVisibility(View.GONE);
}
protected void onProgressUpdate(Integer... progress){
pb.setProgress(progress[0]);
}
public void postData(String valueIWantToSend) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(localhost/reg.php");
try {
// WHAT DO I ADD HERE?? A LITTLE CONFUSED ABOUT THIS PART TOO
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("myHttpData", valueIWantToSend));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
}
}
}
