음악 응용 프로그램을 개발 중입니다. LastFM에서 아티스트의 이미지를로드하고 싶습니다. 이렇게하면됩니다. 1. 클래스 ArtistImageLoader extends BaseGlideUrlLoader을 만들었습니다. 2. getUrl 방법에서 retrofit2를 사용하여 LastFM에서 아티스트의 이미지 URL을 getArtistInfo 방법으로 가져 왔습니다.dagger2와 함께 글라이드를 사용하는 방법
내 문제는 내가 개조 서비스를 투입하는 방법을 모른다는 것입니다. ArtistImageLoader에 요청하십시오. 나는 이런 식으로했지만 NOP 예외가 발생했습니다. lastFmService은 주입되지 않았습니다.
// GlideModule
glide.register(MLocalArtist.class, InputStream.class, new ArtistImageLoader.Factory());
// Use it in onCreate method of ArtistsFragment
DaggerLastFmComponent.builder().activityModule(new ActivityModule(getActivity()))
.netComponent(getNetComponent())
.build().inject(this);
// use this code in onBindViewHolder method of artists recycler adapter
Glide.with(getContext())
.from(MLocalArtist.class)
.load(localArtist)
.into(localArtistViewHolder.ivArtwork);
ArtistImageLoader는
public class ArtistImageLoader extends BaseGlideUrlLoader<MLocalArtist> {
@Inject
LastfmService lastfmService;
public ArtistImageLoader(Context context) {
super(context);
}
@Override
protected String getUrl(MLocalArtist model, int width, int height) {
Call<List<MArtist>> call = lastfmService.getArtistInfo(model.artistName);
try {
List<MArtist> artists = call.execute().body();
if (artists != null && artists.size() > 0) {
Timber.e(artists.get(0).toString());
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
public static class Factory implements ModelLoaderFactory<MLocalArtist, InputStream> {
@Override public ModelLoader<MLocalArtist, InputStream> build(Context context, GenericLoaderFactory factories) {
return new ArtistImageLoader(context);
}
@Override public void teardown() {
}
}
}
당신은 내가 그것을 어떻게 도와 드릴까요? 정말 고맙습니다!
