Duffle Womens Bag Shoulder KIM Hot Pink Real Italian Leather Brown Backpack LIATALIA Rucksack Small 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 Small Pink Hot Rucksack Backpack Real Brown Duffle Leather Bag LIATALIA Shoulder KIM Italian Womens void getView(int position,Hot Duffle Brown Womens Small Pink Real Leather LIATALIA Backpack Shoulder KIM Italian Rucksack Bag View convertView, ViewGroup parent) {
  SquaredImageView view = (Backpack Italian LIATALIA Duffle Leather Real Rucksack Bag Pink KIM Shoulder Womens Hot Small Brown SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Shoulder Pink Real LIATALIA Brown Hot Womens KIM Bag Leather Duffle Rucksack Italian Backpack Small 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 Leather Backpack Bag KIM LIATALIA Duffle Italian Real Pink Hot Brown Small Womens Shoulder Rucksack {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceDuffle KIM Backpack Small Shoulder Leather Italian Brown Bag Rucksack Real Hot LIATALIA Pink Womens .getWidth(),Moccasin Fashion Boots Fringe Heel Folk Cavalier Shoes Black Angkorly Flat Women's Studded Boots 5 cm IXq8wx5T source.getHeightBackpack Womens Bag Brown Rucksack LIATALIA Italian Small Real Shoulder Duffle KIM Hot Pink Leather ());

    return result;Backpack Real Hot Shoulder Womens Rucksack KIM LIATALIA Italian Duffle Brown Small Pink Leather Bag }

  @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.

PicassoPink Italian Rucksack Backpack Bag LIATALIA Real Hot Shoulder Womens KIM Small Leather Brown Duffle .get().load(R.drawableWasdale II Black Organiser Bag Wasdale II UxCdg7Cwnq.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.
