Glide和RecyclerView - 图像搞砸了

Question

我正在尝试使用ImageViews创建RecyclerView。这是我得到的：

正如你所看到的，所有的艺术家封面都搞砸了，而且顺序错了。如果我滚动或重新加载，相应的图像可能会更改。

这是我的适配器onBindViewHolder：

public class ArtistsAdapter extends RecyclerView.Adapter<ArtistViewHolder> implements ListPreloader.PreloadModelProvider 
    private static final String TAG = ArtistsAdapter.class.getSimpleName();
    private final LayoutInflater mInflater;
    private final GlideRequest<Bitmap> fullRequest;

    ArtistsAdapter(Context context) 
        this.mContext = context;
        this.artists = new ArrayList<>();
        this.mInflater = LayoutInflater.from(context);
        this.fullRequest = GlideApp.with(context).asBitmap();
    

    private final Context mContext;

    public List<CompactdArtist> getArtists() 
        return artists;
    

    void swapArtists (List<CompactdArtist> artists) 
        this.artists.clear();
        this.artists.addAll(artists);
        notifyDataSetChanged();
    

    private final List<CompactdArtist> artists;

    @Override
    public ArtistViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
        View view = mInflater.inflate(R.layout.recyclerview_artist_item, parent, false);
        return new ArtistViewHolder(view);
    

    @Override
    public void onViewRecycled(ArtistViewHolder holder) 
        super.onViewRecycled(holder);
        Log.d(TAG, "onViewRecycled: ");
        GlideApp.with(mContext).clear(holder.artistImageView);
        holder.artistImageView.setImageDrawable(null);
    

    @Override
    public void onBindViewHolder(final ArtistViewHolder holder, final int position) 
        Log.d(TAG, "onBindViewHolder: " + position);
        final CompactdArtist current = artists.get(position);

        // holder.setIsRecyclable(false);

        holder.artistImageView.setImageDrawable(null);
        try 
            fullRequest.load(new MediaCover(current))
                .fallback(ImageUtils.getFallback(mContext))
                .into(new ImageViewTarget<Bitmap>(holder.artistImageView) 
                    @Override
                    protected void setResource(@Nullable Bitmap resource) 
                        if (resource == null) 
                            // holder.setIsRecyclable(true);
                            return;
                        

                        holder.artistImageView.setImageBitmap(resource);
                        int color = Palette.from(resource).generate().getMutedColor(0xFFFFFF);
                        try 
                            current.fetch();
                         catch (CouchbaseLiteException e) 
                            e.printStackTrace();
                            holder.artistNameText.setText(R.string.unknown_artist_name);
                        
                        holder.artistBackground.setBackgroundColor(color);
                        holder.bindArtist(current);
                        holder.artistSub.setText(current.getAlbumCount() + " albums");
                        holder.artistNameText.setText(current.getName());

                        // holder.setIsRecyclable(true);
                    

                    @Override
                    public void onLoadCleared(@Nullable Drawable placeholder) 
                        super.onLoadCleared(placeholder);
                        // holder.setIsRecyclable(true);
                    
                );
         catch (IOException e) 
            e.printStackTrace();
        
    

    @Override
    public long getItemId(int position) 
        return artists.get(position).getId().hashCode();
    

    @Override
    public int getItemCount() 
        return this.artists.size();
    

    @NonNull
    @Override
    public List getPreloadItems(int position) 
        return this.artists.subList(position, position + 1);
    

    @Nullable
    @Override
    public RequestBuilder<?> getPreloadRequestBuilder(Object item) 
        MediaCover cover = (MediaCover) item;
        return fullRequest.clone().thumbnail(0.2f).load(cover);

这是我的片段容器中的代码：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) 

    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.fragment_artists, container, false);

    mArtistRecyclerView = rootView.findViewById(R.id.artists_recyclerview);

    LinearLayoutManager layoutManager = new GridLayoutManager(getContext(), 3);
    mArtistRecyclerView.setLayoutManager(layoutManager);

    mArtistsAdapter = new ArtistsAdapter(getActivity());
    mArtistRecyclerView.setAdapter(mArtistsAdapter);
    mArtistRecyclerView.setRecyclerListener(new RecyclerView.RecyclerListener() 
        @Override
        public void onViewRecycled(RecyclerView.ViewHolder holder) 
            ArtistViewHolder artistViewHolder = (ArtistViewHolder) holder;
            GlideApp.with(holder.itemView).clear(artistViewHolder.getArtistImage());
        
    );
    FixedPreloadSizeProvider<MediaCover> coverSizeProvider = new FixedPreloadSizeProvider<>(64, 64);
    RecyclerViewPreloader<MediaCover> preloader = new RecyclerViewPreloader<MediaCover>(GlideApp.with(this), mArtistsAdapter, coverSizeProvider, 2);

    return rootView;

作为奖励，我为我的MediaCover添加了抓取器：

/**

public class MediaCoverFetcher implements DataFetcher<InputStream> 
    private final MediaCover mediaCover;
    private boolean cancelled = false;
    private InputStream stream;

    public MediaCoverFetcher(MediaCover mediaCover) 
        this.mediaCover = mediaCover;
    

    @Override
    public void loadData(Priority priority, DataCallback<? super InputStream> callback) 
        CompactdArtwork artwork = mediaCover.getArtwork();
        try 
            stream = artwork.getImage(ArtworkSize.LARGE);
            if (cancelled) 
                callback.onLoadFailed(new RuntimeException("Cancelled"));
             else 
                callback.onDataReady(stream);
            
         catch (NullPointerException e) 
            callback.onLoadFailed(e);
        
    

    @Override
    public void cleanup() 
        if (stream != null) 
            try 
                stream.close();
             catch (IOException e) 
                e.printStackTrace();
            
        
    

    @Override
    public void cancel() 
        cancelled = true;
    

    @NonNull
    @Override
    public Class<InputStream> getDataClass() 
        return InputStream.class;
    

    @NonNull
    @Override
    public DataSource getDataSource() 
        return DataSource.LOCAL;

我想它来自回收部分，但我不知道如何解决这个问题。正如您在代码中看到的那样，我尝试了setIsRecyclable，但是我会收到错误，说出无法匹配的调用，而且它无法修复它
