이제 거의 다 왔다. 프레그먼트 패키지 몇개와 포토뷰 패키지쪽만 손보면된다.
먼저 ViewPagerActivity를 변환해보자.
1. activity_view_pager.xml 를 복사해준다.
xml에 보면 gujc.directtalk9.photoview.HackyViewPager... 부분이 있는데, 이를 처리하기위해 포토뷰 패키지에서
HackyViewPager를 복사하고 변환해준다. 그것은 아래와 같다.
위를 가지고 xml 젤 아래쪽 코드를 이와 같이 수정했다.
툴바도 androidx용 툴바로 바꾸어주었다.
그동안 변환하는 방식과 마찬가지로 이것저것 처리를 해주면
ViewPagerActivity는 아래와 같이 변환 할 수 있다.

그 다음 다시 ChatActivity로 돌아와서, 아래 UserListInRoomFragment 부분을 추가해보자.
UserListinRoomFragment를 변환하다보니 필요한 것들은
아래와 같았다.
drawble에서 shape_rectangle.xml
아래는 변환한 코드 전체이다.

드디어 ChatModule부분을 어느정도 완성했다. 다시 메인액티비티로 돌아와서 다시 한번 체크를 해보면, 추가가 안되있는 부분들은 아래와 같다.
먼저 R.menu 부분은 Resources부분의 메뉴 패키지를 의미하므로 기반 앱에서 복사를 해오면 된다.
그러면 action logout 부분도 추가된다.
이제 드디어 위의 Fragment들을 추가해볼때이다. 이것만 추가하면 대부분의 변환이 끝난다.
일단 UserListFragment 를 추가하면 아래와 같이 변환할 수 있다.

아래는
ChatRoomFragment 를 변환한 것이다. 이에 관련 xml을 추가해주고... 변환한 kt 는 아래와 같다.
변환하기에 앞서 ChatRoomModel이 필요해서 이를 추가하였다.
혹시 Fragment xml에 대한 id가 찾아지지않는다면
import com.google.firebase.firestore.* 를 지워보자.
item_chatroom도 필요해서 추가하였다.
