ManagementActivity 소스

 

 

 

 

 

ManagementActivity에 다음을 추가해줍니다.

 

saveList생성자를 생성해줍니다.

 

amdin계정만 saveList를 다룰수있게 해줍니다.

 

UserListAdapter로 돌아가서 다음을 추가해줍니다.

 

manageMent테이블로 돌아가서 saveList를 추가해줍니다.

 

userListAdpaper로 돌아가서 saveList또한 삭제가 가능하게 만들어줍니다.

 

ManagemetnActivity 클래스로 돌아와서

searchUser에대한 함수를 작성해줍니다.

먼저 userList를 클리어한다음

saveList 즉 전체 회원들의 크기만큼 반복합니다.

getUserID즉 내가 찾는 회원이 포함되어 있을경우에만 add하면서 추가해줍니다

그리고 adapter의 notifyDataSetChanged를 통해서 정보를 알려줍니다.

 

UserListAdapter로 돌아가서 아까의 remove를 회원검색시에도 삭제할수있도록 변경해줍니다.

현재의 회원정보가userID와 동일한 정보를 가지고 있다면 해당 회원을 삭제해줍니다.
