사용자 지정 목록보기의 단추 사용

Question

내 안드로이드 프로젝트에서 모든 값을 서버에서 검색하여 listview에 표시하는 사용자 지정 목록보기를 사용하고 있습니다. 나는 listview 항목에있는 textview와 함께 버튼을 가지고 있습니다. 버튼을 클릭하면 같은 그룹의 textview에서 값을 가져 와서 경고 상자에 표시하는 것과 같은 버튼 기능을 원합니다. 데이터를 검색하고 성공적으로 표시하지만 목록의 textview 값을 얻기 위해 버튼을 사용하는 방법을 알아낼 수 없습니다. 사전 도움을 주셔서 감사합니다 ... 내 코드는 아래에 게시됩니다.

Answer 1

다음과 같이 몇 가지 변경 사항을 추가 할 수 있습니다.

ContactAdapter extends ArrayAdapter<Contacts> 
List<Contacts> list = new ArrayList<Contacts>(); 

그리고이 라인 :

String name,age,height,weight,symptom; 

당신은

Answer 2

name = nt.newList.get(position).getName(); 

내가 그것을 생각 다음과 같아야합니다.

name = list.get(position).getName();
