multithreathing

[emanuelx]

boas pessoal há pouco tempo iniciei-me na programação para android, que é a mesma coisa que java, mas agora que queria usar o multithreathing e não consigo usar pois lá no meio do procedimento tem refererencias para mudar uma barra de progresso e umas alertbox.

já tentei de várias formas mas não estou a conseguir, será que alguem me pode explicar como funcionam?

final ProgressBar barra = (ProgressBar) findViewById(R.id.barra);

    AlertDialog.Builder alertbox = new AlertDialog.Builder(this);

    String xmltext="";

        

    

    try {
            int barrap=0;
            barra.setVisibility(0);
            URL textUrl = new URL("http://www.legendas-zone.org/rss1.php");
            BufferedReader bufferReader = new BufferedReader(new InputStreamReader(textUrl.openStream()));  
            String StringBuffer;
            
            barra.setMax(bufferReader.readLine().length());
            while ((StringBuffer = bufferReader.readLine()) != null) {
                barrap+=StringBuffer.length();
                barra.setProgress(barrap);
                xmltext += StringBuffer;
                }
            bufferReader.close();   
            System.out.println(xmltext);
            Thread thread = new Thread((Runnable) this);
            thread.start();
            
            lerxml(xmltext.replace("&", "e"));
            Toast.makeText(this, "Concluído!", Toast.LENGTH_SHORT).show();
        } 
                catch (MalformedURLException ex) 
            {            
                alertbox.setMessage(ex.toString());
                alertbox.show();
        } 
                catch (IOException e) 
            {
                alertbox.setMessage(e.toString());
                alertbox.show();
            }

Aonde é que está o método run()?

Porque é que fazes cast?

private void carregardados()
{
    final ProgressBar barra = (ProgressBar) findViewById(R.id.barra);
        
    
    final Handler myHandler = new Handler();
        
                
        (new Thread(new Runnable() {
                    
                    public void run() {
                        try {
                            int barrap=0;
                            String xmltext = null;
                        URL textUrl = new URL("http://www.legendas-zone.org/rss1.php");
                        final BufferedReader bufferReader = new BufferedReader(new InputStreamReader(textUrl.openStream()));  
                        String StringBuffer;                        
                            myHandler.post(new Runnable() {
                                public void run() {
                                    try {
                                        maxbarra(bufferReader.readLine().length());
                                    } catch (IOException e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                    }
                                }
                            });
                            while ((StringBuffer = bufferReader.readLine()) != null) {
                                     barrap+=StringBuffer.length();
                                     barra.setProgress(barrap);
                                     xmltext += StringBuffer;
                                     }
                                bufferReader.close();  
                                sendmsg("aa");
                            //lerxml(xmltext.replace("&", "e"));
                        } 
                        catch (MalformedURLException ex) 
                    {            
                        sendmsg(ex.toString());
                        
        	        } 
                        catch (IOException e) 
                    {
                        sendmsg(e.toString());
                        
                    }
                    
                    }
                })).start();
                
            }
