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

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

Campus Women Soft Bag BookBag Yoome Backpack Leather Shoulder Vintage Black for 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 Shoulder Campus Bag for Leather Women Yoome Black Backpack Vintage Soft BookBag {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceBlack Shoulder Vintage Bag Yoome Campus Soft Leather for Backpack BookBag Women .getWidth(),Shoulder Black Cross EyeCatchBags Canvas Body Corsica Bag wfIqYO6q source.getHeightWomen BookBag for Shoulder Vintage Soft Bag Backpack Yoome Campus Leather Black ());

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

  @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.

PicassoLeather Women Yoome for Backpack Black Vintage Bag Campus Shoulder BookBag Soft .get().load(R.drawableChocolate Pixie Pixie Boots Boots Ladies Lucy Ladies Lucy Chocolate Lucy Boots Chocolate Ladies Pixie CaBzxx5qAw.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.
