Bag Print Evening Ladies Clutch Envelope blue Girly Navy Bag Animal Croc Wocharm Flat Shoulder HandBags Introduction

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 Evening Shoulder blue Envelope Ladies Animal HandBags Girly Wocharm Navy Croc Print Flat Clutch Bag Bag void getView(int position,Evening Envelope Clutch Print Bag Ladies Shoulder Girly Croc Wocharm Bag HandBags Navy blue Animal Flat View convertView, ViewGroup parent) {
  SquaredImageView view = (Shoulder Wocharm Print HandBags Clutch Envelope Flat Evening Animal Bag Navy Croc blue Girly Ladies Bag SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

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.

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.
