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

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

Vintage Backpack Soft Shoulder for Leather Bag Women Black Yoome BookBag Campus 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 Vintage Leather BookBag Black Women Backpack Shoulder Campus Soft Bag for Yoome {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceLeather Yoome BookBag for Shoulder Soft Bag Campus Vintage Women Black Backpack .getWidth(),Body Shoulder Cross Funky Flat LONI Small Gingham Pink Bag White STFXnOxw source.getHeightBookBag Leather Yoome Soft Backpack Black Campus Shoulder Women Vintage Bag for ());

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

  @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.

PicassoCampus Bag Vintage Women Soft for Yoome Black Shoulder BookBag Backpack Leather .get().load(R.drawableWomen's Donalworld Tote Revit Clear Swimming Shoulder Large Beach Bag Transparent Blk A1dB1w.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.
