[Android] Intent 예제

MainActivity에서 Join IN 버튼을 누르면

정보를 입력하는 JoinActivity를 보여주고

JoinActivity에서 정보입력 완료후 Join 버튼을 누르면

MainActivity의 텍스트 뷰에 정보들을 보여줍니다.

체크되어 있지 않으면, product layout을

체크되어 있으면 advertise layout을 inflate 하는 예 입니다.

추가로 activity_join.xml과 JoinActivity.java가 필요합니다.

또한 Manifist.xml에서 JoinActivyt에 대한 내용을 추가해야 합니다.

마지막으로

아래의 내용을 Manifist의 application안에 추가해줍니다.

 <activity
