내 애플리케이션의 상대 레이아웃을 동적으로 생성하는 방법을 알고 싶습니다. 나는 서버에서 얻은 각 항목에 대해 새로운 상대 레이아웃을 생성하려고합니다.안드로이드에서 상대 레이아웃을 동적으로 생성하기
다음과 같이 내가 생성 할내 XML 뷰는 다음과 같습니다

하지만 작동하지 않습니다. 내가 뭔가 잘못하고있는거야. 제발 뭔가를 제안
코드에서 작동하지 않는 것은 무엇입니까? 현재 무슨 일이 일어나고 있습니까? [재사용 가능한 레이아웃 살펴보기] (http://developer.android.com/training/improving-layouts/reusing-layouts.html)를 권장하고 필요에 따라 추가하십시오. 당신이 보여준 방향은 관리가 어려울 수있는 것처럼 보입니다. – CodeMonkey
내가 Question_Layout의 각 하위 요소로 전달하는 매개 변수를 추측합니다. 즉, textViews가 오류를 표시하고 있습니다. 또한 내가 try catch 블록을 사용할 때 ArrayIndexOutOfBound 오류라고 말합니다. –
'ArrayIndexOutOfBound'는 매우 구체적입니다. LogCat을 게시하고 오류의 원인이되는 코드 줄을 지적 할 수 있습니까? – CodeMonkey
