안녕하세요~ viewpager로 webview 화면을 구성하였습니다.
webview 안에 url만 바뀌는 거라 이렇게 구현했는데요,,
제가 슬라이드로 TAB3을 선택하고 다른메뉴 갔다가 다시 이 화면으로 오면 초기화가 안되어 바로 TAB3번 화면부터 띄워집니다.
TAB1 화면으로 띄우고자 onPageChangeListener.onPageSelected(0); 도 넣어봣는데 소용이 없네요..
제가 원하는것은 다른화면으로 갔을때 모든화면이 다 remove 되고 이 메뉴를 선택했을때 초기화면부터 다시 띄우는건데.. 몇일째 도돌이표입니다 ㅠㅠ
방법이나 힌트좀 부탁드립니다~
