Images add much-needed context and visual flair to Android applications. Picasso allows for hassle-free image loading in your application—often in one line of code!

Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

Many common pitfalls of image loading on Android are handled automatically by Picasso:

  • Handling ImageView recycling and download cancelation in an adapter.
  • Complex image transformations with minimal memory use.
  • Automatic memory and disk caching.

Features

Adapter Downloads

Adapter re-use is automatically detected and the previous download canceled.

Vcun8051 Handbag Shoulder Ladies mpk Women's Hobo Satchel Bag Large Tote Shopping Bags Colored Multicolour Vintage Canvas Image Transformations

Transform images to better fit into layouts and to reduce memory size.

Picasso.get()
  .load(url)
  .resize(50, 50)
  .centerCrop()
  .into(imageView)

You can also specify custom transformations for more advanced effects.

Pass an instance of this class to the transform method.

Place Holders

Picasso supports both download and error placeholders as optional features.

Picasso.get()
    .load(url)
    .placeholder(R.drawable.user_placeholder)
    .error(R.drawable.user_placeholder_error)
    .into(imageView);

A request will be retried three times before the error placeholder is shown.

Resource Loading

Resources, assets, files, content providers are all supported as image sources.

Picasso.get().load("file:///android_asset/DvpvklR.png").into(imageView2);
Picasso.get().load(new File(...)).into(imageView3);
