Is there any way from which we can detect images are loading from cache in picasso?

问题

as title suggest I want to check whether images are loading from cache or not.

I've done something like this but couldn't succeeded.

Picasso.with(getApplicationContext())
                .load(data.get(position).get("product_image"))
                .into(viewHolder.imgViewIcon, new Callback() {

                    @Override
                    public void onSuccess() {
                        viewHolder.imgViewIcon.setVisibility(View.VISIBLE);
                        if (Picasso.LoadedFrom.NETWORK != null)
                            YoYo.with(Techniques.ZoomIn).duration(1200)
                                    .playOn(viewHolder.imgViewIcon);
                        viewHolder.placeholder.setVisibility(View.GONE);
                    }

                    @Override
                    public void onError() {

                    }
                });

Please anyone have batter option then tell me. Thanks.

Use Picasso's setIndicatorEnabled(true) to detect where the image is loaded from.

Picasso picasso = Picasso.with(context);
picasso.setIndicatorsEnabled(true);

//...
picasso.load("http://example.com/image.jpg").into(myImageView);

A colored ribbon will appear in the top left corner.
