이제 그리드보기에서 이미지를 표시하고 있습니다. 정상적으로 작동합니다. 그 그리드보기에서 몇 가지 이미지를 선택하려고 해요, 배열 변수 (예 : 위치를 선택하면 여러 이미지 위치를 원하는 위치 1, 4, 10. 내가 그 특정 위치 ID를 원한다면 나는 그것을 배열을 저장하고 싶습니다 1,4,10,15 등). 아래에 활동 및 어댑터 코드를 입력하겠습니다. 미리 감사드립니다.gridview 여러 위치를 가져 와서 배열 변수에 저장하는 방법

시간이 Recyclerview –
에 이동왔다 목록에서 선택한 위치를 추가 할 수 있습니다. –
네, 그냥 Recyclerview가 더 강력하다고 말할 수 있습니다 ... 당신의 그리드 아이템에 체크 박스 나 다른 것들이있어서 그들을 선택하기 위해서입니까? –
