안드로이드 - 로그인, 회원가입 관리자모드 (삭제기능) 추가 (2)

 

이전 관리자모드를 만들어서 회원들의 리스트를 보여준 뒤 회원들을 삭제하는 기능까지 해보았는데

 

이번엔 검색기능도 추가하는 것을 따라해보았다. 

 

 

먼저 검색기능을 하는 EditText를 Activity_management.xml 화면에 추가할 것이다.

 

 

< Activity_management.xml >

 

[ 추가코드 ]

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/search"
        android:hint="검색"/>
