listview api에 이미지로드

Question

현재 이미지를 listview에로드하려고합니다. 설정 방법은 이름 위치 등과 같은 객체의 모든 속성을 설정하는 중입니다. 그 중 하나가 이미지 일 수 있습니다. 현재 URL로 이동하는 메서드를 호출하는 이미지를 설정할 때마다 이미지를 검색하기 위해 토큰을 사용해야합니다. 일단 내가 가져온 이미지가 변수 비트 맵 이미지를 검색합니다.

이것은 매우 느리고 끔찍한 것처럼 보입니다. 일부 제 3자를 보았지만 직접 이미지 뷰에로드합니다. 이미지 뷰를 사용하기 위해 객체를 설정해야하며, 이미지를 재사용 할 필요가 있기 때문에 어떻게 든 이미지를 볼 필요가 있습니다.

Answer 1

이 해방 Android-Universal-Image-Loader 시도 그것의 GIF입니다.

1. 그리고 메모리와 거시기에 캐시 된 것으로 설정합니다. Configuration Linked

2. 사용법 :

ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleton instance // Load image, decode it to Bitmap and display Bitmap in ImageView (or any other view // which implements ImageAware interface) imageLoader.displayImage(imageUri, imageView);
