How to get Bitmap from SimpleDraweeView?

I want to get Bitmap from SimpleDraweeView of Fresco lib, and save it to SD Card. SimpleDraweeView is child class of ImageView so it should support getDrawable() but calling this method throws ClassCastException

BitmapDrawable bitmapDrawable = (BitmapDrawable) viewHolder.drawee.getDrawable();

ClassCastException: com.facebook.drawee.generic.RootDrawable cannot be cast to android.graphics.drawable.BitmapDrawable

What is the wayout for this?

Solution

  • s1rius's answer mentioned by Morrison helped me. Here's the code that I used.

    ImageRequest downloadRequest = ImageRequest.fromUri(uri);

CacheKey cacheKey = DefaultCacheKeyFactory.getInstance().getEncodedCacheKey(downloadRequest, context);

if (ImagePipelineFactory.getInstance().getMainFileCache().hasKey(cacheKey)) {
     BinaryResource resource = ImagePipelineFactory.getInstance().getMainFileCache().getResource(cacheKey);
     File cacheFile = ((FileBinaryResource) resource).getFile();
     File savedImageFile = new File(Constants.APP_PATH_SAVED_QUOTES, "M1iS1" + "_" + currentPosition + ".jpg");
}

    Then I copied cacheFile into savedImageFile.
