Problémáim vannak az akciósáv megvalósítása során (amit azt hiszem, most az eszköztár váltotta fel). Amit szeretnék, egy kis legördülő menü 3 ponttal, ahol megadhatok néhány lehetőséget, például beállításokat és krediteket. Megpróbáltam úgy beállítani, hogy a menü megjelenjen a homelistview.java oldalon. Úgy érzem, körbejártam a különböző megoldásokat, és minden alkalommal új hibaüzenetet kaptam, és mindig ugyanarra a helyre mutat, amelyet alább említettünk.
setSupportActionBar(toolbar);
Eredetileg azt hittem, hogy azért, mert nem tartalmaztam a setContentView(R.layout.activity_main); de nem volt boldog, beleértve a 2 tartalommegtekintést is. Bármilyen segítséget szívesen vennénk.
Itt a kódom.

Az Eszköztár eszköztár csak az onCreate-ben van deklarálva/inicializálva, ezért a hatókör kimaradt ebből a metódusból...
