如何使用 Glide android 工作室延遲加載圖像？

Question

我想在我的 cardview 中延遲加載圖像，但它不起作用下面是我的代碼，但我很困惑如何使用 glide 延遲加載圖像

        int width = metrics.widthPixels;
        int height = metrics.heightPixels;
        BitmapRequestBuilder builder =
                Glide.with(context)
                        .load(Constants.IMAGE_DOWNLOAD + pathName)
                        .asBitmap();
        FutureTarget futureTarget = builder.into(width, height);
        return (Bitmap) futureTarget.get();
    }

    private Bitmap loadImageForNoti(Context context, String pathName) throws ExecutionException, InterruptedException {
        DisplayMetrics metrics = mContext.getResources().getDisplayMetrics();
        int width = metrics.widthPixels;
        int height = metrics.heightPixels;
        BitmapRequestBuilder builder =
                Glide.with(context)
                        .load(pathName)
                        .asBitmap();
        FutureTarget futureTarget = builder.into(width, height);
        return (Bitmap) futureTarget.get();
    }```

使用transition效果可以流暢快速地加載圖像。

GlideApp  
.with(context)
.load(url)
.transition(DrawableTransitionOptions.withCrossFade()) //for loading image smoothly and fastly.
.placeholder(placeHolderUrl)
.error(errorImageUrl)
.fitCenter()
.into(imageView);

想要更多 animation 和順利加載圖像。 看這里https://bumptech.github.io/glide/doc/transitions.html
