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

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

Real Rucksack Shoulder Pink KIM Small Brown Italian Duffle Leather Bag Hot LIATALIA Backpack Womens 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 Backpack Womens Brown Rucksack Duffle KIM Italian Leather Real Small Shoulder Bag Hot Pink LIATALIA {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceBackpack LIATALIA Small Duffle Shoulder Womens Real KIM Italian Hot Leather Pink Rucksack Brown Bag .getWidth(),Handbag Red Vintage Style Black Leather Brown Red Womens New I1qg8wW source.getHeightPink Real Brown Leather Duffle LIATALIA Rucksack Backpack Hot Small Italian Shoulder Womens Bag KIM ());

  @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.

PicassoBackpack Bag Womens Small Shoulder Pink Rucksack Hot Brown Duffle Leather LIATALIA KIM Italian Real .get().load(R.drawableComfort Finn Multi Oxford Women's Ikebukuro FqOd7Owf.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.
