imageview와 text가있는 사용자 정의 imageadapter

Question

어떻게 이미지 자체와 텍스트가 포함 된 gridview에 이미지를 추가 할 수 있습니까? 사용자 지정 이미지 어댑터를 만들려고했지만 somereason에서 작동하지 않습니다. imgView.setLayoutParams (new GridView.LayoutParams (85, 85));

새로운 질문 이미지 어댑터에서 추가하고 제거 할 수있는 방법은 무엇인가요? 하나의 사진과 같은 동작이 필요합니다. 그리고 텍스트 사진이있는 동일한 사진을 추가하여 2 개의 사진을 만들어야합니다. A를 하나 ..

Answer 2

'imgView'는 R.layout.album_image에서 부풀어 오른 ConvertView의 자식이며 LinearLayout 이외의 것입니다. 따라서 레이아웃 매개 변수를 설정하는 동안 부모 ViewGroup 유형이어야합니다. 그래서 LinearLayout.LayoutParams는 정상적으로 작동합니다.

'ConvertView'의 크기를 설정하고 싶다면 GridView.LayoutParams가 필요합니다. beConz 'ConvertView'가 GridView 인 parent에 추가됩니다.
