여기서 메뉴 버튼을 이용해서 리니어레이아웃을 두칸 아니면 세칸 으로 자바코드로 구현할려고해요 그런데

여기서 계속 막히더라구요

llLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT,8));
            llLayout1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT,1));
            llLayout2.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT,1));
            llLayout3.removeAllViews();
            llLayout4.removeAllViews();

이렇게 구현하는게 아닌가요..? 이렇게하면 3번이랑 4번만 안에 내용만 없어져요

저는 아예레이아웃 통째로 없애버리고 싶은데 부탁드립니다

Answer 1

무슨 내용인지 이해하기가 약간 어려우나..

리니어를 생성하는것은 별로 어려운것이 아닐테고..

생성한 리니어를 부모뷰에 붙이는것은 부모뷰.addview()로 자식들을 생성하면되고,

뷰들을 전부 삭제 하고싶으면 부모뷰.removeAllViews(); 로 하시면 됩니다.

removeAllviews는 해당하는 뷰의 자식뷰를 모두 삭제하는 것이기때문에

 llLayout3.removeAllViews();
 llLayout4.removeAllViews();

이 두가지를 사용하면 당연히 3,4번안의 내용만 없어지죠..

저 두가지 뷰를 가지고있는 뷰를 remove해야 합니다..
