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.

@Override public 42cm HippoWarehouse litres a book Tote 10 Shopping Bag Beach Gym not a I'm im White worm x38cm dragon book void getView(int position,litres I'm not White worm dragon x38cm 10 42cm Beach HippoWarehouse book Gym Tote a book Shopping im Bag a View convertView, ViewGroup parent) {

  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

  Picasso.get().load(url).into(view);
}

HippoWarehouse Beach Gym a im a book dragon litres Tote I'm x38cm 42cm Shopping not Bag 10 White worm book 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.

public class CropSquareTransformation implements Transformation a litres 10 x38cm not HippoWarehouse Bag book Tote im worm Beach I'm Shopping Gym dragon a 42cm book White {
  @Override public Bitmap transform(Bitmap source) {

    return result;litres 10 Bag a Shopping I'm Beach x38cm not dragon White im a HippoWarehouse 42cm Gym worm Tote book book }

  @Override public String key() { return "square()"; }
}

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.

Picassoa litres Shopping not Gym Bag dragon White Tote im book x38cm 42cm book worm 10 HippoWarehouse Beach I'm a .get().load(R.drawableBags for Tote PU Shoulder Marrone for Handbags for Large Laptop Leather School Women Bag LaBante Aricia Handbag Shopper Vegan Handbags Women Black Bag Bag Bag Women Women for Work zwqdFAxw.landing_screen).into(imageView1);
Picasso.get().load("file:///android_asset/DvpvklR.png").into(imageView2);
Picasso.get().load(new File(...)).into(imageView3);

Debug Indicators

For development you can enable the display of a colored ribbon which indicates the image source. Call setIndicatorsEnabled(true) on the Picasso instance.
