Android SearchView weder durchsuchbare Aktivität gestartet noch onNewIntent() genannt

Question

Also versuche ich eine Suchfunktion in meiner App zu implementieren. Ich habe der Anwendungsleiste ein SearchView hinzugefügt und mein Manifest so konfiguriert, dass es die Absichten auf die richtigen Aktivitäten zeigt. Aber ich habe eine spezielle Situation: Ich möchte zusätzliche Informationen in die Absicht setzen, die das SearchView generiert, um es an meine SuchableActivity zu übergeben (in meinem Fall die SearchEventsActivity-Klasse). Um dies zu erreichen, wollte ich meine MainActivity-Klasse durchsuchbar machen, die Absicht mit onNewIntent() erfassen, die zusätzlichen Informationen in eine neue Absicht einfügen und diese verwenden, um meine eigentliche Suchaktivität zu starten. Aber aus irgendeinem Grund, obwohl ich ziemlich sicher bin, mein manifest ist richtig, onNewIntent() wird nie in MainActivity genannt

Answer 1

Ich glaube, mein Problem ist, dass das SDK nicht meine durchsuchbare Konfiguration auf die Suche in meiner Tätigkeit instanziiert einen Anknüpfungspunkt. Ich habe keine Ahnung, warum das so ist, aber ich habe eine Abhilfe, nämlich tun, diese Kopplung programmatisch im onCreateOptionsMenu (Menü Menü) -Methode von MainActivity.java wie so:

SearchView searchView = (SearchView) menu.findItem (R.id.action_search).item.getActionView (); 
SearchManager searchManager = (SearchManager) getSystemService (Context.SEARCH_SERVICE); 
searchView.setSearchableInfo (searchManager.getSearchableInfo (getComponentName ())); 

Ich hoffe, das jemand in der Zukunft hilft:)
