확장 가능 목록의 하위 목록에서 이미지보기에 액세스

Question

다음 소스 코드가 있습니다. 확장 가능한 목록에 이미지 목록, 이미지 버튼과 같은 일부보기가있는 하위 목록이 있습니다. 이벤트 처리를 원합니다. 이러한 견해들. 다음에 대한 소스 코드를 제공하십시오.

공개 클래스 ExpList extends ExpandableListActivity { ImageView imageView, heart; 보기보기; ArrayList count = new ArrayList(); // 개인 컨텍스트 컨텍스트; 확장형 목록 어댑터 데모 madapter; 정적 최종 문자열 음영 [] [] 회색 { "Episode1"의 = { // 차양, "Episode1", "Episode1", "Episode1", "Episode1"}, 블루 { "Episode2의 // 차양 ","Episode4 Episode2 ","Episode2 ","Episode2 ","Episode2 " "Episode2 "},

Answer 1

나는 당신을위한 해결책을 가지고 있습니다. 너무 간단합니다. 2 차원 배열을 사용하여 어댑터 데이터를 뷰에 표시하도록하십시오. 한 어린이의 데이터에 액세스 (예 : Textview 문자열, Imageview 이미지 리소스 등)하려는 경우 제거해야합니다. 당신의 expandablelistview에서와 같은 위치를 갖는 2 차원 배열의 요소는 그 위치에서 변경된 데이터를 가진 새로운 요소를 추가합니다. 그런 다음 adapter.notifyDataSetChanged()를 호출하십시오. 코드를 이해하기가 약간 어렵습니다. 코드는 다음과 같습니다.

 childs.get(1).remove(1); 
    childs.get(1).add(1, new ChildData("changed textview", BitmapFactory.decodeResource(getResources(), R.drawable.no_avatar))); 
    adapter.notifyDataSetChanged();
