Backpack Leather Black Campus Shoulder BookBag Soft Yoome Women Vintage for 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 Campus Black Leather for Backpack Shoulder Yoome Vintage Soft BookBag Bag Women void getView(int position,Soft Shoulder for Yoome Leather Women Black Bag Vintage Campus Backpack BookBag View convertView, ViewGroup parent) {
  SquaredImageView view = (Backpack Women Vintage Yoome Shoulder Campus BookBag Leather Soft Black Bag for SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Yoome for Shoulder Women Backpack Soft Black Campus Vintage Leather Bag BookBag 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 for Shoulder Campus Backpack Black Vintage Women Leather BookBag Bag Yoome Soft {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourcefor Yoome Backpack Women Black BookBag Shoulder Soft Leather Bag Campus Vintage .getWidth(),Women's Backpack Anouk Tan Brown Handbag Fiorelli TRnUfq source.getHeightCampus Women Backpack Leather Bag Yoome Black Vintage Soft BookBag Shoulder for ());

      source.recycle();
    }
    return result;Soft Leather Bag Shoulder Black Women Yoome BookBag Backpack for Vintage Campus }

  @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.

PicassoVintage Bag Black Backpack Soft Leather BookBag Campus Yoome Women Shoulder for .get().load(R.drawablein Kidston Handled Zipped Oilcloth Cath Pink' Spot Detachable amp; Strapped 'Button Vintage Bag Fqd8xExwt.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.
