Nothing happens on re selecting the menu item in dropdown

Question

I'm using the below code in onCreate to display a dropdown menu in the actionbar. The code works fine, it shows the dropdown menu and performs the tasks that i've added in onNavigationItemSelected. But his happens only once i.e if i select Menu Item 2 for the first time the Toast shows "Selected" message and the asynctask is executed. When i reselect Menu Item 2 nothing happens! Why this problem occurs and how can i get rid of this it?

getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
        final LinearLayout mainLayout = (LinearLayout) this
                .findViewById(R.id.linearLayout1);

        ActionBar.OnNavigationListener navigationListener = new OnNavigationListener() {

            @Override
            public boolean onNavigationItemSelected(int itemPosition,
                    long itemId) {

                if (actions[itemPosition].toString().equals("exit")) {

                    System.exit(0);
                }
                if (actions[itemPosition].toString().equals(
                        "Menu Item 2")) {

                    Toast.makeText(getApplicationContext(),"Selected" ,Toast.LENGTH_LONG).show();
                    code="2";
                    //call to an asynctask

                }
                return false;
            }
        };

    getActionBar().setListNavigationCallbacks(adapter, navigationListener);

you have need to read these links then your problem will solve out your strategy of calling menu items are not correct so follow these links

http://developer.android.com/reference/android/view/MenuItem.html
http://developer.android.com/guide/topics/ui/menus.html
http://www.androidhive.info/2011/09/how-to-create-android-menus/
Handling a Menu Item Click Event - Android
Creating an Options Menu in Android

These codes are more useful to make drop down item selection items

code are above :- go to Project and res folder then menu/then your .xml file for menu items

  <menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
      android:icon="@drawable/menu_addnew"
      android:title="new_game"
      android:showAsAction="ifRoom"/>
<item android:id="@+id/help"
      android:icon="@drawable/menu_addnew"
      android:title="help" />
 </menu>


  and then in java file you have use this code

   public class AndroidMenusActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

// Initiating Menu XML file (menu.xml)
  @Override
public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.layout.menu, menu);
    return true;
}
 @Override
public boolean onOptionsItemSelected(MenuItem item)
{

    switch (item.getItemId())
    {
    case R.id.new_game:
        // Single menu item is selected do something
        // Ex: launching new activity/screen or show alert message
        Toast.makeText(AndroidMenusActivity.this, "Bookmark is Selected", Toast.LENGTH_SHORT).show();
        return true;

    case R.id.help:
        Toast.makeText(AndroidMenusActivity.this, "Save is Selected", Toast.LENGTH_SHORT).show();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
