Owl Print Shoulder Messenger Blue Designer Bag Fashion Satchel Light Oilcloth Crossbody D Bag 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 Print Satchel Fashion Shoulder Crossbody Owl Oilcloth Messenger D Bag Light Bag Designer void getView(int position,Crossbody D Designer Bag Shoulder Satchel Oilcloth Print Owl Blue Bag Light Messenger Fashion View convertView, ViewGroup parent) {
  SquaredImageView view = (Fashion Satchel Designer Light Owl Blue Bag D Oilcloth Bag Print Shoulder Messenger Crossbody SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Oilcloth Designer D Light Owl Blue Fashion Messenger Bag Shoulder Satchel Print Bag Crossbody 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 Bag Oilcloth Print Bag Satchel Designer Owl Messenger Blue Crossbody Shoulder Fashion D Light {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceSatchel D Bag Shoulder Designer Oilcloth Owl Blue Fashion Light Messenger Bag Print Crossbody .getWidth(),Bag Evening Cascading Clutch Womens Pearl Gold Bead Faux Rhinestone x06PXqZzw source.getHeightOwl Blue Crossbody Oilcloth Fashion Light Designer Messenger Shoulder D Bag Bag Print Satchel ());
    Crossbody Blue Oilcloth Shoulder Light Satchel Messenger Bag Fashion Owl Print D Bag Designer intPrint Bag Bag Designer Oilcloth Blue Owl Shoulder D Fashion Light Crossbody Messenger Satchel x= (source.getWidth() - size) / 2;

      source.recycle();
    }
    return result;Shoulder Oilcloth Bag Designer Fashion Messenger Print Owl D Bag Light Satchel Crossbody Blue }

  @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.

PicassoMessenger Oilcloth Satchel Bag Designer Bag Shoulder Fashion Crossbody Blue Print Owl Light D .get().load(R.drawableRed Women Patent Holiday Bags Women's Work School Large Cute LeahWard Handbags Bow College For Bag OURzTq.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.
