Cómo pasar datos de AsyncTask a Ui Thread

Question

Estoy implementando una clase asyncTask para cargar los datos del servidor. Ya tengo la información y quiero pasarla al hilo de la interfaz de usuario, pero no sé cómo.

Este es el código:

public class InboxHandler extends FragmentActivity implements OnLineSelectedListener { 

    static final int GET_CODE = 0; 
    private TextView textView3, textView2; 
    private Button button1, button2, button3; 
    private LinearLayout tab1, tab2, tab3; 
    private CheckBox cbVerPorCategoria; 
    private ActionBar actionBar; 
    private TextView txtTitle; 
    private Settings settings; 
    FragmentTransaction fragmentTransaction; 
    BottomPanel bottomPanel; 
    public List<OrderRequest> orderRequestArray; 
    private OrderRequestParser orderRequestParser; 
    public static int number; 
    int clickCounter = 0; 
    private boolean doubleBackToExitPressedOnce = false; 
    private static Context context; 
    DataLoader dataLoader; 
    private MyAsynckTask myAsynckTask; 

    public InboxHandler(){} 

    public List<OrderRequest> getOrderRequestArray() { 
     return orderRequestArray; 
    } 

    public void setOrderRequestArray(List<OrderRequest> orderRequestArray) { 
     this.orderRequestArray = orderRequestArray; 
    } 

    public static Context getContext() 
    { 
     return context; 
    } 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_inbox); 

     context = this.getApplicationContext(); 

     settings = Settings.getInstance(); 
     settings.setPrefs(getSharedPreferences(settings.getPREFERENCES(), Activity.MODE_PRIVATE)); 
     settings.setPrefsEditor(settings.getPrefs().edit());   
     settings.getPrefsEditor().putBoolean("isLoggedIn", true); 
     settings.isVistaSimple = true; 

     actionBar = (ActionBar) findViewById(R.id.actionbar); 

     initComponents(); 
     prepareActionBar(); 
    } 

    private void initComponents() { 

     try { 
      MyAsynckTask myAsynckTask = new MyAsynckTask(this); 
      myAsynckTask.execute(); 

      //HERE I USED A SUGGESTION IN A SIMILAR QUESTION. THAT IS: PASS THE ACTIVITY TO THE ASYNCTASK, AND FROM IT, SAVE IN THE ACTIVITY, THE DATA THAT IU WANT FROM THE ASYNCTASK. I DO THAT, BUT IN THE ACTIVITY, THE DATA IS NULL I SUPPOSE DUE TO, I DONT EVEN SEE IN THE LOGCAT, THE FOLLOWING RESULT: 

      try{ 
       Log.e("e", ""+this.getOrderRequestArray().get(0).getDocNumber()); 
      } catch(Exception e){ 
       e.printStackTrace(); 
      } 

//If you see the onPostExecute, I test if the data I want is there. and it is there! I set that to the list of the class InboxHandler, but in the above code, when i try to test if it is there, it´s not. And that code don´t even appear in logcat. The "Log.e("e", ""+this.getOrderRequestArray().get(0).getDocNumber());" nor the "e.printStackTrace();" 

      bottomPanel =new BottomPanel(); 
      Bundle bundle = new Bundle(); 
      bundle.putSerializable("arrayPedidos", (Serializable) orderRequestArray); 
      bottomPanel.setArguments(bundle); 

      //actionBar.setTitle("Inbox"); 
      NotificationFragment notificationFragment = new NotificationFragment(orderRequestArray, actionBar); 

      Bundle bundleNotificationFragment = new Bundle(); 
      bundleNotificationFragment.putString("title", "Inbox"); 
      notificationFragment.setArguments(bundleNotificationFragment); 

      fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
      fragmentTransaction.add(R.id.frame_list_container, notificationFragment); 
      fragmentTransaction.add(R.id.frame_bottom_panel, bottomPanel);  
      fragmentTransaction.commit(); 

     } 
     catch(Exception e) 
     { 
      e.printStackTrace(); 
     } 

    } 

    private class MyAsynckTask extends AsyncTask { 

     private String stringMensaje; 
     public List<OrderRequest> orderRequestArray; 
     private OrderRequestParser orderRequestParser; 
     private Request request; 
     private Settings settings; 
     private InboxHandler inboxHandler; 

     public MyAsynckTask(InboxHandler inboxHandler){ 
      this.inboxHandler = inboxHandler; 
     } 

     @Override 
     protected Object doInBackground(Object... params) { 

      List<OrderRequest> array = this.getOrderRequests(); 
      settings = Settings.getInstance(); 


      if(array != null){ 
       settings.setOrderRequestArray(array); 
       orderRequestArray = array; 
       Log.e("orderRequestArray", "Me trajo el orderRequestArray en doInBackground!"); 
      } else { 
       Log.e("orderRequestArray", "No me trajo el orderRequestArray en doInBackground!"); 
      } 

      return array; 

     } 

     @Override 
     protected void onPostExecute(Object result) { 
      super.onPostExecute(result); 

      List<OrderRequest> array = (List<OrderRequest>) result; 

      this.setOrderRequestArray(array); 

      if(orderRequestArray != null){ 
       inboxHandler.setOrderRequestArray(orderRequestArray); 
       Log.e("orderRequestArray", "is not null en onPostExecute!"); 
      } else { 
       Log.e("orderRequestArray", "is null en onPostExecute!"); 
      } 


      if(inboxHandler.getOrderRequestArray() != null){ 
       Log.e("inboxHandler.getOrderRequestArray()", "is not null en onPostExecute!"); 
      } 
      else { 
       Log.e("orderRequestArray", "is null en onPostExecute!"); 
      } 
     } 


     public List<OrderRequest> getOrderRequests() { 

      orderRequestParser = new OrderRequestParser(); 
      orderRequestArray = new ArrayList<OrderRequest>(); 
      List<OrderRequest> orderRequestArray = orderRequestParser.listOrderRequest(); 

      Settings.getInstance().setOrderRequestArray(orderRequestArray); 
      if(orderRequestArray != null){ 
       Log.e("orderRequestArray", "Me trajo el orderRequestArray en getOrderRequestArray!"); 
      } else { 
       Log.e("orderRequestArray", "No me trajo el orderRequestArray en getOrderRequestArray!"); 
      } 

      return orderRequestArray; 

     } 

     public void setOrderRequestArray(List<OrderRequest> orderRequestArray) { 
      this.orderRequestArray = orderRequestArray; 
     } 

     public List<OrderRequest> getOrderRequestArray() { 
      return orderRequestArray; 
     } 
    } 

Answer 1

protected void onPostExecute(Object result) 

se está ejecutando en hilo de interfaz gráfica de usuario, puede acceder a elementos de la GUI allí.

y sólo debería ser el:

 try{ 
      Log.e("e", ""+this.getOrderRequestArray().get(0).getDocNumber()); 
     } catch(Exception e){ 
      e.printStackTrace(); 
     } 

y

Bundle bundle = new Bundle(); 
    bundle.putSerializable("arrayPedidos", (Serializable) orderRequestArray); 
    bottomPanel.setArguments(bundle); 

no puedo ver ninguna razón, ¿por qué es esta pregunta abajo votó.
