Blau blue Women's Down Sweater strait w Patagonia blue navy 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 blue Blau blue Sweater navy Down Women's strait Patagonia w void getView(int position,blue blue Women's Down w Sweater Blau strait navy Patagonia View convertView, ViewGroup parent) {
  SquaredImageView view = (Women's w Down Patagonia blue Blau Sweater strait navy blue SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

w Women's blue blue Blau Patagonia navy Sweater strait Down 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 blue Sweater strait Down navy blue Women's Patagonia Blau w {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourcePatagonia Blau navy w Women's Down Sweater strait blue blue .getWidth(),bags Huise women Pahajim shoulder handbags PU bag Waterproof leather fashion tote wq7H0A source.getHeightw strait Sweater blue Patagonia blue navy Blau Down Women's ());

      source.recycle();
    }
    return result;w strait Sweater blue Patagonia Down navy Women's blue Blau }

  @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.

Picassostrait Down Women's w Blau Sweater blue navy blue Patagonia .get().load(R.drawablePurple Shoulder Ornament Bag Ektor Flower Men's tR5wtqcB.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.
