панель действий с прядильщиком Android (простой ответ для кого-то)

Question

У меня возникли проблемы с добавлением спиннера вместо имени приложения в моей панели действий. Имейте в виду, что этот вопрос задан раньше, но все ответы в значительной степени одинаковы либо с простой коррекцией одной строки, а затем ссылкой на thiers прекрасный пример на сайте google dev: http://developer.android.com/guide/topics/ui/actionbar.html#Dropdown андроидных документов, но для новичков I находят его в сухарях и оставляют крошечные кусочки ключевой информации.

public class MainProgram extends Activity implements OnNavigationListener { 

    /** 
    * Mobile Service Client reference 
    */ 
    private MobileServiceClient mClient;  
    private ConnectWithService service; 

    /** 
    * Progress spinner to use for table operations 
    */ 
    private ProgressBar mProgressBar; 

    /** 
    * Sensor stuff 
    */ 
    SensorManager mSensor; 
    Detection orientation; 

    //Spinner Listener 
    mOnNavigationListener = new OnNavigationListener() { 
      // Get the same strings provided for the drop-down's ArrayAdapter 
      String[] strings = getResources().getStringArray(R.array.action_list); 

      @Override 
      public boolean onNavigationItemSelected(int position, long itemId) { 
      //toast 
       Toast toast = Toast.makeText(this, "whoop whoop!", toast.LENGTH_SHORT); 
       toast.show(); 
      }

        android.R.layout.simple_spinner_dropdown_item); 


     //innitialize Sensor Manager 
     mSensor = (SensorManager)getSystemService(SENSOR_SERVICE); 


     //signin 
     try {

      // Mobile Service URL and key 
      mClient = new MobileServiceClient(

        "secret", 
        this).withFilter(new ProgressFilter());   

     } catch (MalformedURLException e) { 
      createAndShowDialog(new Exception("There was an error creating the Mobile Service. Verify the URL"), "Error");

     } 
    } 

    private void authenticate() { 

      // Login using the Google provider. 
      mClient.login(MobileServiceAuthenticationProvider.MicrosoftAccount, 
       new UserAuthenticationCallback() { 

        @Override 
        public void onCompleted(MobileServiceUser user, 
          Exception exception, ServiceFilterResponse response) { 

         if (exception == null) { 
          createAndShowDialog(String.format(
              "You are now logged in - %1$2s", 
              user.getUserId()), "Success"); 
          service = new ConnectWithService(mClient,user.getUserId()); 
          orientation = new Detection(mSensor); 
         } else { 
          createAndShowDialog("You must log in. Login Required", "Error"); 
         } 
        } 
       }); 
     } 

    //start sensors camera etc if needed 
     protected void onResume() { 
      super.onResume(); 

      if(orientation!=null) 
       orientation.startSensorsListening(); 
     } 

     // stop sensors etc 
     protected void onPause() { 
      super.onPause(); 
      orientation.stopSensorListening(); 
     } 

} 

Theres по крайней мере, две ошибки я думаю, mOnNavigationListener должен быть где-то еще setnavigationMode() имеет ошибку

Answer 1

не используют OnNavigationListener с (ActionBar.NAVIGATION_MODE_LIST) использования:

final ActionBar bar = getActionBar(); 
    bar.setDisplayShowCustomEnabled(true); 
    bar.setCustomView(R.layout.action_bar_custom); 
then all as normal. 

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?>....
