현재지도에서 다른 것들을 보여주는 Android 앱을 개발 중입니다. 나는 완벽하게 작동하는 내비게이션 서랍과 음식점 및 먹을 장소와 같은 가까운 장소를 반환하는 일부 Google지도 활동이 있습니다. 문제는지도 활동을 열기위한 탐색 창 항목을 클릭하면 기본지도 만로드된다는 것입니다. 맵 액티비티가 별도의 프로젝트에서 완벽하게 작동한다고 덧붙이고 싶습니다. 아래에서 내 코드를 찾을 수 있습니다. NavigationActivity의 코드 :안드로이드 내비게이션 서랍 빈 Google지도 표시

내가 탐색 서랍 조각으로 잘 작동하는지 알고 있지만 내가 나오지 않았어에 대한 코드 기능을 잃지 않고 내지도 활동을 조각으로 바꾸는 올바른 방법을 찾지 못했습니다. 조언이 도움이됩니다. 미리 감사드립니다.
가 대단히 감사합니다! –
