recyclerview 항목에서 이미지를로드하기 전에 스피너를 추가하는 방법

Question

데이터 바인딩을 사용하여 레이아웃 및 글라이드 라이브러리를 사용하여 어댑터 클래스에서 이미지를로드합니다. 이제는 각 행에 이미지를로드하기 전에 진행률 회 전자를 첨부하고 싶지만 현재는로드하는 방법을 모르겠습니다. ??

감사

여기에 어쩌면 당신은 회 전자의 진행 상황을 보여주는에 리스너를 추가 할 수 있습니다 내 어댑터 클래스

입니다.

Glide.with(imageView.getContext()) 
     .load(ApiHelper.BASE_URL + url) 
.listener(new RequestListener<String, GlideDrawable>() { 
    @Override 
    public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) { 
     yourSpinnerProgress.setVisibility(View.GONE); 
     return false; 
    } 

    @Override 
    public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) { 
     yourSpinnerProgress.setVisibility(View.GONE); 
     return false; 
    } 
}) 
.into(imageView); 

을 그리고 레이아웃에 yourSpinnerProgress를 추가 배치 &의 루트에 대한 RelativeLayout의를 사용하는 것을 잊지 마세요 :

이 당신의 코드를 변경할 수 있습니다.
