안드로이드 : 회원 관리 프로젝트(디자인)

 

 

 

 

LoginActivity로 생성

 

1.어플리케이션 화면 디자인

 

implementation 'com.android.volley:volley:1.1.0'

 

Gradle Scripts -> build.gradle 에서 아래를 추가해준다.

(네트워크 통신과 관련된 라이브러리: 나중에 DB에 이용)

 

액티비티를 추가해준다.

액티비티 이름은 RegisterActivity를 해준다.

(회원이 회원이 아닐때 회원가입 시켜주는 Activity)

 

이때 한개더 MainActivity도 추가해준다

(로그인이 성공했을 때 화면)

 

 

세개의 엑티비티와 세개의 디자인을 만들었다.
