私は音楽アプリケーションを開発しています。私はLastFMからアーティストのイメージをロードして、このようにします。 1.私はクラスArtistImageLoader extends BaseGlideUrlLoaderを作成しました。 2. getUrlメソッドではretrofit2を使ってlastFMからアーティストの画像URLをgetArtistInfoメソッドで取得しました。glide with dagger2の使用方法
私の問題は、修理のサービスを注入する方法を知らずに、ArtistImageLoaderにリクエストを行うことです。私はこのようにしましたが、私はNOP例外があります。 lastFmServiceは注射されなかった。
// 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);
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() {
}
}
}
ArtistImageLoaderあなたは私がそれを行うのを助けることができますか？どうもありがとうございます！
