Ich habe Probleme damit, dass meine SearchView in der ActionBar eine Absicht auslöst, die von meiner SearchActivity empfangen wird. Ich denke, das Problem liegt irgendwo im Manifest/XML, weil das Logcat nicht einmal das Log in der onCreate-Methode der SearchActivity anzeigt. Ich habe theseresources und andere (einschließlich SO-Antworten) verwendet, um es zu versuchen und zu implementieren, aber hatte kein Glück gehabt.SearchView löst keine SearchActivity aus
manifestieren:
