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.
