Bunun için sonsuza dek mücadele ediyordum ve sonunda bir miktar yardımla anlamaya çalışıyorum. Uygulamamın ana ekranındaki (Ana Etkinlik) araç çubuğuna bir gezinme çubuğu eklemeyi deniyorum. Şu anda, araç çubuğum, XML'imdeki DrawerLayout ve nav çekmecesi simgesiyle birlikte gösterilmiyor. çekmeceyi açmak için sağa kaydırmam gerekiyor. Sonra çekmecedeki bir öğeye tıkladığımda görünüm değişmez. Çekmecelerde bulunan 2 parçanın her ikisi de parçalardır. Kodumda XML'imin yanı sıra bir sorun olduğuna inanıyorum ama android XML dosyaları ile iyi değilim.Gezinme çubuğu gösterilmiyor ve çalışmıyor üzerinde çalışıyor

Android studio kullanıyor musunuz? Dahili şablonla demo oluştur ve bu kodu seninkiyle karşılaştır. bunu da tutulmadan yapabilirsin. – Harry
Evet android stüdyosu kullanıyorum. Sanırım büyük sorun benim xml'im ve ayrıca çekmecede tıklanan parçanın yeni ekran olarak nasıl ayarlandığını –
