[안드로이드] javascript 의 window.open , window.close 연동하기

우리가 웹브라우저에 이미 탑재된 기능이라 지나칠수 있는데, 새창 띄우기 기능인 javascript 의 window.open 함수도 안드로이상에서는 따로 만들어 주어야 한다.

 

아래의 소스중에 WebChromeClient 상속받은 MyWebChromeClient 클래스내에 onCreateWindow 함수가 바로 이놈인데 이를 오바라이딩 해주도록 하자.

 

아래 소스는 window.open 창이 Dialog 형태로 그안에  newView 형태로 열리는데,

필자가 엄청 삽질했던 부분이 open 은 잘되는데, close 가 안되어 한참 애먹었었다.

 

결국, 64라인, 65라인이 핵심이다.

 

                        dialog.dismiss();
                        newWebView.loadUrl("javascript:self.close();");

 

dialog 를 닫고,

javascript:self.close() 를 돌려서, 77라인의 onCloseWindow 함수가 돌아가도록 하는것이다.
