Question

 

 

안녕하세요~^^ 안드로이드 입분10일차 입니다.

텝메뉴마다 웹뷰링크를걸었는데 텝메뉴이동시 엑티비티를 새로고침하고싶습니다.

자바책을사서 열씸히 공부중이지만 당장 어플을완성해야해서 거의7일째 3시간씩 잠을청하며 열공을하고있어요~

아래는 해당텝메뉴소스입니다. 해당코드부분을 자세하게  알려주시면 감사하겠습니다. 

많이고민하다 질문올립니다.~ 급하게 목적만해결하고싶은 마음은 조금도없어요 근데 주위의압박으로 당장완성을해야해서

부탁좀드릴꼐요~!!화이팅~!!

Answer 1

1. static Handler를 이용하는 방법있습니다.

각 액티비티 마다 static Handler를 만드시고

탭 액티비티에 해당 핸들러를 등록합니다.

그리고 탭 액티비티에서는 탭 호스트에 onTabChangeListener를 등록하여

탭 이동시 해당 핸들러로 새로고침하라는 메시지를 전달하면 되겠네요.

 

2. 브로드캐스트를 이용하는 방법이 있습니다.

커스텀 브로드캐스트를 만드셔서 각 액티비티마다 다른 브로드캐스트 리시버를 등록하시고

탭 이동시 그에 맞는 브로드캐스트를 날려주면 될 것 같네요.
