Navigation Drawer에 대해서 쉽고, 알고 싶은 것을 속 시원히 알려드릴게요. 우선 기본적인 프로젝트를 이클립스로 생성했다면 아래와 같은 소스를 확인할 수 있습니다.

어디를 손대야 내가 원하는데로 화면 전환이 될지가 궁금해 질텐데요. Navigation Drawer 프로젝트는 살펴보면 Fragment라는 녀석이 있습니다. 그래서 우리는 Activity를 사용하지 않고 Fragment를 사용할 거에요.
보여주고 싶은 화면을 두 개만 만들어 보겠습니다. 우선은 액티비티를 두개 추가해 줍니다. 그리고 소스를 수정할거에요.

많이 보던 소스입니다. 여기서 아래와 같이 수정 할게요.

Activity를 Fragment로 수정했습니다. 이렇게 더 추가할 화면을 액티비티로 생성한 다음 위와 같이 Fragment로 수정합니다. 다시 메인 액티비티로 넘어가보도록 하겠습니다. 이제 거의 다 됐어요~

50번 째 줄 부터 처음 MainActivity와 변경된 부분을 확인하면 되요. Fragment를 사용하여 Activity위에서 그려지는 부분을 변경하는 거에요. Fragment에 대한 이해가 없는 분이라면 Fragment에 대한 이해부터 하시고 이것을 보시면 더 쉽게 이해할 수 있어요.
화면을 꾸며주고 싶은 부분은 Fragment에서 추가하면됩니다. Activity와 생명주기도 조금 다르고, 사용하는 방법도 조금 다르니 꼭 Fragment에 대해 이해하도록 해요~
「 Tip!! 」
1. 안드로이드에서 제공하는 기본 Navigation Drawer 프로젝트를 생성한다.
2. 구성하고 싶은 화면을 Activity로 생성한다.
3. Activity 를 Fragment 로 변경한다.
4. MainActivity에서 Fragment를 replace 한다. 그러면 원하는 화면으로 휙휙 전환된다.
