Question

我正在使用 palette-v7：23.2.1 与滑翔：3.7.0 ，如下所述，但有时深色鲜艳的颜色未成功提取，我得到默认颜色。

在我清除滑动缓存并再次尝试使用相同的图像后，我得到了正确的颜色。奇怪的是，总是提取明亮的鲜艳色彩，而不是暗色。

可能是什么问题以及如何解决？

在onCreateView（）中：

Glide.with(mContext)
    .load(artworkUrl)
    .asBitmap()
    .into(new BitmapImageViewTarget(mArtworkInToolbar) {
        @Override
        public void onResourceReady(Bitmap bitmap, GlideAnimation anim) {
            new Palette.Builder(bitmap).generate(paletteAsyncListener);
            super.onResourceReady(bitmap, anim);
        }
    });

监听器：

public final Palette.PaletteAsyncListener paletteAsyncListener =
    new Palette.PaletteAsyncListener() {

    @Override
    public void onGenerated(Palette palette) {
        if (palette == null) return;

        int default = ContextCompat.getColor(mContext, R.color.colorPrimary);
        int color = palette.getVibrantColor(default); //always ok
        int colorDark = palette.getDarkVibrantColor(default); //not always

        // --- Setting the color --
    }
};

***Here this is worked for me*** 
make a class name PaletteBitmap.java

public class PaletteBitmap {
    public final Palette palette;
    public final Bitmap bitmap;

    public PaletteBitmap(@NonNull Bitmap bitmap, @NonNull Palette palette) {
        this.bitmap = bitmap;
        this.palette = palette;
    }
    Bitmap getBitmap()
    {
        return bitmap;
    }
}
class PaletteBitmapResource implements Resource<PaletteBitmap> {
    private final PaletteBitmap paletteBitmap;
    private final BitmapPool bitmapPool;

    public PaletteBitmapResource(@NonNull PaletteBitmap paletteBitmap, @NonNull BitmapPool bitmapPool) {
        this.paletteBitmap = paletteBitmap;
        this.bitmapPool = bitmapPool;
    }

    @Override public PaletteBitmap get() {
        return paletteBitmap;
    }

    @Override public int getSize() {
        return Util.getBitmapByteSize(paletteBitmap.bitmap);
    }

    @Override public void recycle() {
        if (!bitmapPool.put(paletteBitmap.bitmap)) {
            paletteBitmap.bitmap.recycle();
        }
    }
}
class PaletteBitmapTranscoder implements ResourceTranscoder<Bitmap,  PaletteBitmap> {
    private final BitmapPool bitmapPool;

    public PaletteBitmapTranscoder(@NonNull Context context) {
        this.bitmapPool = Glide.get(context).getBitmapPool();
    }

    @Override public Resource<PaletteBitmap> transcode(Resource<Bitmap> toTranscode) {
        Bitmap bitmap = toTranscode.get();
        Palette palette = new Palette.Builder(bitmap).generate();
        PaletteBitmap result = new PaletteBitmap(bitmap, palette);
        return new PaletteBitmapResource(result, bitmapPool);
    }

    @Override public String getId() {
        return PaletteBitmapTranscoder.class.getName();
    }
}


**Now in Your onCreateView() do like this**
Glide.with(this).fromUri().asBitmap()
                .transcode(new  PaletteBitmapTranscoder(this),PaletteBitmap.class)
                .fitCenter()load(uri).into(new  ImageViewTarget<PaletteBitmap>(imageView){

        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        @Override
        protected void setResource(PaletteBitmap resource) {
            imageView.setImageBitmap(resource.getBitmap());
            int colorP =  resource.palette.getMutedColor(ContextCompat.getColor(context, R.color.colorPrimary));
        int   colorD=resource.palette.getDarkMutedColor(ContextCompat.getColor(context,R.color .colorPrimaryDark));
           // dowhatever you want
        }
    });;

使用Glide的调色板有时无法加载深色鲜艳的颜色
