ListView 내의 ListView는 하나의 항목 만 표시합니다.

-2

저는 빚진 사람이나 돈을 추가 할 수있는 부채 관리자 앱을 개발하고 있습니다. 해당 인물은 ListView에 표시되어야하고 채무는 해당 인물 내의 ListView에 표시되어야합니다. 현재 나는 더미 데이터로 각 두 부채 항목과 함께 두 사람을 추가하고 있습니다. 두 사람 모두 바깥 ListView에 표시되지만 각각 하나의 부채 항목 만 표시됩니다.ListView 내의 ListView는 하나의 항목 만 표시합니다.

아이디어가 있으십니까?

요는 확장 ListView에을 시도해야는 here는 확장 목록보기의 예입니다.

그룹에 속한 사람의 이름과 부채를 해당 그룹의 하위 그룹에 추가하십시오.
