[안드로이드 스튜디오] Android SearchView 자동완성 검색

Android Studio SearchView 기능을 이용하면 검색처리가 좀 더 편하다.

검색어 자동완성같은 기능을 구현하기 위한 방법이라고 봐도 된다.

먼저, http://abhiandroid.com/ui/searchview 게시글을 다운로드 해서 본인 PC에서 직접 테스트한다.

다운로드 하려면 성명과 E-Mail 을 입력하고 나면 Dropbox 에 올려진 파일을 다운로드 할 수 있다.

아래 내용은 서버에 있는 자료를 ArrayList 에 저장하고 저장된 자료를 기반으로 SearchView 구현에 필요한 것만 발췌한 것이다.

앱 build.gradle 설정 내용 예시
