그래서 사용자가 WiFi 또는 4G를 사용하여 로그인 한 후 데이터를 가져올 것인지 결정할 수있는 앱을 만들고 있습니다. 누구든지 여기에 추가하고 싶지 않으면 나중에 결정하십시오.) 그래서 현재 MainActivity.java가 있는데 이것은 (아직 구현하지 않은) 로그인을 처리 할 것이고 Navigation Drawer에 NavDrawerActivity.java를 가지고 있습니다. 이제 분명히 "로그인"을하면 Nav Drawer로 이동합니다. 그러나 사용자가 로그인하기 전에 Wi-Fi 또는 데이터를 사용할 것인지 아닌지를 선택할 수 있어야하고 로그인 한 후에 선택할 수 있어야합니다. 두 부분으로 된 질문입니다. 어떻게 구현할까요? 글쎄, 로그인 화면에 넣는 것이 좋은 생각입니까? 또는 WiFi를 변경하지 않는 한 항상 WiFi를 사용하도록 기본값을 설정해야하며 WiFi가 활성화되어 있지 않으면 사용하도록 설정해야합니까?다른 활동에서 Nav Drawer 설정 사용하기
