this my asynctask

private class NuevoPostVideo extends AsyncTask<String, Integer, String>{



     @Override
    protected String doInBackground(String... params) {
         objAcceso = new AccesoBd();
         String jsRes= "";

         SharedPreferences userDetails = getParent().getSharedPreferences("MisPreferencias", MODE_PRIVATE);

        try{

            File f = new  File(sDireccionFoto); 

            FileBody bin = new FileBody(f);

            StringBody  from = new StringBody( Integer.toString(userDetails.getInt("Id",0)));

          StringBody id_recurso = new StringBody(Integer.toString(idEvento));
          StringBody titulo_body = new StringBody(txtVTitulo.getText().toString());
          StringBody ficha = new StringBody("null");


         MultipartEntity reqEntity = new MultipartEntity();
         reqEntity.addPart("imageFile", bin);
         reqEntity.addPart("from",from);
         reqEntity.addPart("idrecurso",id_recurso);
         reqEntity.addPart("titulo", titulo_body);
         reqEntity.addPart("ficha", ficha);


        objAcceso.conxDatosInPost(params[0],reqEntity);
        jsRes="ok";

    }
    catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();

     }finally{return jsRes;}

        }
     @Override
     protected void onPostExecute( String result) {


         if (result.equals("ok")){

         SharedPreferences userDetails = getParent().getSharedPreferences("MisPreferencias", MODE_PRIVATE);
         DetalleEvento objd = new DetalleEvento();
         objd.setTipo(1);
         objd.setFecha(objAcceso.FechaActualinglesa());
         objd.setTituloPost(sTituloPost);
         objd.setImagen(btmImagenElegida);
         objd.setUrl(sDireccionFoto);
         objd.setAutor(userDetails.getString("Nombre","Usted"));



         objAdapterDetalles.arrayDatos.add(0,objd);

         objAdapterDetalles.notifyDataSetChanged();
         lstDatos.setSelection(1);
         dOpciones.dismiss();
         dHacerVideo.dismiss();

         }
            Pro.dismiss();
            prgVProgreso.setVisibility(View.INVISIBLE);
        }
     @Override
        protected void onPreExecute() {

            //prgVProgreso.setVisibility(View.VISIBLE);
        Pro.show();
            //Pro.incrementProgressBy(10);


    }
     @Override
      public void onProgressUpdate(Integer... args){
          Pro.setProgress(args[0]);
                    } 




 }

this my function of conexion "Look at this line of my doinbhackgroud" (objAcceso.conxDatosInPost(params[0],reqEntity); )

 public  String conxDatosInPost(String Direccion, MultipartEntity Parametros) throws Exception {
        BufferedReader in = null;
        try {
            HttpClient client = ClienteHttp();
            HttpPost request = new HttpPost(Direccion);
            request.setEntity(Parametros);
            HttpResponse response = client.execute(request);
            in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

            StringBuffer sb = new StringBuffer("");
            String line = "";
            String NL = System.getProperty("line.separator");
            while ((line = in.readLine()) != null) {
                sb.append(line + NL);
            } 
            in.close();

            String result = sb.toString();
            Log.d("El resultado de cnxposin es :-----------  ",  result +"fn");

            return result;
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

¿as I can do to update my progress dialog While the connection lasts ?

find not the way to do this

I would like to know if there was the possibility of some listener progresslistener style?

please could help me or give me a hint

Answer 1

ultimately solve my problem as follows

this is how my code is

public class NuevoPostVideoConProgreso extends AsyncTask<String, Integer, String>{

             ProgressDialog dialogProgreso;
            long totalSize;

                 @Override
                protected String doInBackground(String... params) {
                     objAcceso = new AccesoBd();
                     String res = "";
                     SharedPreferences userDetails = getParent().getSharedPreferences("MisPreferencias", MODE_PRIVATE);
                    try{


                    CMultipartContador objconSub = new CMultipartContador(new CMultipartContador.ProgressListener() {

                        @Override
                        public void transferred(long num) {
                            // TODO Auto-generated method stub

                            float antes = (float)(num /(float) totalSize);
                            float despues =(float)(antes * 100);

                            int numero = (int) despues;


                            publishProgress(numero);//(int) ((num /(float) totalSize) * 100));
                        }
                    } );

                        File f = new  File(sDireccionFoto); 

                        FileBody bin = new FileBody(f);

                        StringBody  from = new StringBody( Integer.toString(userDetails.getInt("Id",0)));

                      StringBody id_recurso = new StringBody(Integer.toString(idEvento));
                      StringBody titulo_body = new StringBody(txtVTitulo.getText().toString());
                      StringBody ficha = new StringBody("null");


                    // MultipartEntity reqEntity = new MultipartEntity();
                     objconSub.addPart("imageFile", bin);
                     objconSub.addPart("from",from);
                     objconSub.addPart("idrecurso",id_recurso);
                     objconSub.addPart("titulo", titulo_body);
                     objconSub.addPart("ficha", ficha);

                    totalSize= objconSub.getContentLength();
                   // dialogProgreso.setMax((int)totalSize);

                    objAcceso.conxDatosInPostAsynctask(params[0],objconSub);



                dialogProgreso.setProgress(100);

                    res= "ok";





                }
                catch (Exception e) {
                    // TODO: handle exception
                    e.printStackTrace();

                 }finally{return res;}

                    }
                 @Override
                 protected void onPostExecute( String result) {

                     dialogProgreso.setProgress(100);
                     dialogProgreso.dismiss();
                     dOpciones.dismiss();
                     dHacerVideo.dismiss();


                     LlenarEvento();




                 }
                 @Override
                    protected void onPreExecute() {
                     dialogProgreso = new ProgressDialog(getParent());
                        dialogProgreso.setMessage("Subiendo...");
                        dialogProgreso.setIndeterminate(false);
                        //dialogProgreso.setMax(100);
                        dialogProgreso.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                        //dialogProgreso.setProgress(0);
                        dialogProgreso.setCancelable(false);
                        dialogProgreso.show();
                        //dialogProgreso.setProgress(3);


                }
                 @Override
                  public void onProgressUpdate(Integer... args){
                      dialogProgreso.setProgress(args[0]);
                                } 




             }

            private ImageView aniadirImagen(Bitmap btmi){
                ImageView img= new ImageView(getParent());

                img.setImageBitmap(btmi);
                btmi.recycle();
                return img;
            }

and this is my new class

public class CMultipartContador extends MultipartEntity {


private final ProgressListener listener;

public CMultipartContador(final ProgressListener listener)
{
    super();
    this.listener = listener;
}

public CMultipartContador(final HttpMultipartMode mode, final ProgressListener listener)
{
    super(mode);
    this.listener = listener;
}

public CMultipartContador(HttpMultipartMode mode, final String boundary, final Charset charset, final ProgressListener listener)
{
    super(mode, boundary, charset);
    this.listener = listener;
}

@Override
public void writeTo(final OutputStream outstream) throws IOException
{
    super.writeTo(new CountingOutputStream(outstream, this.listener));
}

public static interface ProgressListener
{
    void transferred(long num);
}

public static class CountingOutputStream extends FilterOutputStream
{

    private final ProgressListener listener;
    private long transferred;

    public CountingOutputStream(final OutputStream out, final ProgressListener listener)
    {
        super(out);
        this.listener = listener;
        this.transferred = 0;
    }

    public void write(byte[] b, int off, int len) throws IOException
    {
        out.write(b, off, len);
        this.transferred += len;
        this.listener.transferred(this.transferred);
    }

    public void write(int b) throws IOException
    {
        out.write(b);
        this.transferred++;
        this.listener.transferred(this.transferred);
    }
}

Answer 2

You can use a handler to update ProgressDialog according to the status of stuff happening in the doInBackground(..) of AsyncTask. I think this example will be perfect for you. Just send the Handler a Message using handler.sendmsg(msg) so that it would update the ProgressDialog.

Answer 3

check out the following example from official java doc:

private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
     protected Long doInBackground(URL... urls) {
         int count = urls.length;
         long totalSize = 0;
         for (int i = 0; i < count; i++) {
             totalSize += Downloader.downloadFile(urls[i]);
             publishProgress((int) ((i / (float) count) * 100));
             // Escape early if cancel() is called
             if (isCancelled()) break;
         }
         return totalSize;
     }

     protected void onProgressUpdate(Integer... progress) {
         setProgressPercent(progress[0]);
     }

     protected void onPostExecute(Long result) {
         showDialog("Downloaded " + result + " bytes");
     }
 }
