Android-onOptionsItemSelected método llamado dos veces
He implementado ActionBarSherlock
con el SupportMapFragment
guiado por la respuesta aceptada de esta pregunta. Todo funciona bien. Pero el único problema es que el método onOptionsItemSelected
se llama dos veces. Aquí está el código-
@Override public boolean onOptionsItemSelected( com.actionbarsherlock.view.MenuItem item) { switch (item.getItemId()) { case R.id.navigation: Log.d("tag","text"); break; } return super.onOptionsItemSelected(item); }

En su método onOptionsItemSelected
no llame al método onOptionsItemSelected
al final
return super.onOptionsItemSelected(item);
En cambio devuelve verdadero.
@Override public boolean onOptionsItemSelected( com.actionbarsherlock.view.MenuItem item) { switch (item.getItemId()) { case VIEW_PLACES_MENU_ITEM: Toast.makeText(getActivity(), EXTRA_EVENT_CATEGORY, Toast.LENGTH_SHORT).show();//This toast is displayed two times. // TODO clear markers if any clearmarkers(); // TODO put place markers PreferenceManager.getDefaultSharedPreferences(getActivity()).edit() .putInt(PREF_MAP_VIEW, VIEW_LOC).commit(); putLocationMarkers(); break; case VIEW_EVENTS_MENU_ITEM: // TODO clear markers if any clearmarkers(); // TODO put event markers PreferenceManager.getDefaultSharedPreferences(getActivity()).edit() .putInt(PREF_MAP_VIEW, VIEW_EVENT).commit(); putEventMarkers(); break; default: return super.onOptionsItemSelected(item); } return true; }
Yo tuve el mismo problema. Lo que funcionó para mí:
reemplazar
return super.onOptionsItemSelected(item);
con
return true;
Y no hacer la llamada súper en onOptionsItemSelected. Espero que esto funcione para usted también.
