                Picasso.with(context).load(imagesList.get(position).getImage()).into(holder.imgSlider);

            //View v = holder.imgSlider.getDrawable();
            if (holder.imgSlider != null) {
                BitmapDrawable drawable = (BitmapDrawable) holder.imgSlider.getDrawable();
                Bitmap bitmap = drawable.getBitmap();
                Bitmap blurredBitmap = blur(bitmap);
                holder.mediaBackground.setImageBitmap(blurredBitmap);
            }
            else{

its a arraylist of type "profile media" – sudarshan Oct 17 '16 at 13:38
profile media is serializable class – sudarshan Oct 17 '16 at 13:38

use `into(android.widget.ImageView target, Callback callback)` and do your stuff in the callback – pskink Oct 17 '16 at 13:41

If `drawable`is null then maybe it's because Picasso works asynchronously: at the time where `Bitmap bitmap = drawable.getBitmap();` is executed, the drawable has not yet been loaded. – Bö macht Blau Oct 17 '16 at 13:42
ok let me try this – sudarshan Oct 17 '16 at 13:43
@0X0nosugar what is solution then? – sudarshan Oct 17 '16 at 13:44
sudarshan @pskink just provided the solution for you – Alex Oct 17 '16 at 13:46
ok @Alex i will try it – sudarshan Oct 17 '16 at 13:47
Do like pskink said - check e.g. this [SO post](http://stackoverflow.com/a/28056058/5015207) – Bö macht Blau Oct 17 '16 at 13:47
but actually `into(Target target)` is even better as you have to call `setImageBitmap` with the blurred bitmap – pskink Oct 17 '16 at 14:02
thank you so much @pskink and 0X0nosugar it works like charm. Thousand likes for your answer. – sudarshan Oct 17 '16 at 14:06
did you use `into(Target target)`? – pskink Oct 17 '16 at 14:06
@pskink yes into(Target target) was useful but into(target, callback) does the work here.. – sudarshan Oct 17 '16 at 14:08
is it possible to achieve it by using into(Target) instead of into(target, callback)? – sudarshan Oct 17 '16 at 14:09
`into(Target target)` is better as it gives you the loaded `Bitmap` as a parameter in `onBitmapLoaded(android.graphics.Bitmap bitmap, Picasso.LoadedFrom from)` method – pskink Oct 17 '16 at 14:11
@pskink then how can i get callback? if i use only into(Target target) but not into(Target target, Callback) – sudarshan Oct 17 '16 at 14:17
Target is a callback, see http://square.github.io/picasso/2.x/picasso/com/squareup/picasso/Target.html – pskink Oct 17 '16 at 14:17
