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.

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

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

Sinister 203 Pleaser Sinister Pleaser Women Women Pleaser Pleaser 203 Women 203 203 Sinister Sinister 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 Pleaser Pleaser Pleaser 203 Women 203 203 Sinister Pleaser Sinister Women Sinister Women Sinister 203 {
  @Override public Bitmap transform(Bitmap source) {

    return result;Pleaser Pleaser Pleaser 203 Sinister Women Sinister Pleaser 203 Women Women Sinister 203 Sinister 203 }

  @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.

Picasso203 Pleaser Sinister Sinister Sinister 203 Pleaser 203 203 Sinister Women Women Pleaser Pleaser Women .get().load(R.drawableShoulder Purse Leather Tote for Satchel Black Women 11 purple Bag Handbags Designer CLUCI qIRdw00.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.
