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

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

Vintage BookBag Bag Backpack Leather for Women Black Soft Campus Shoulder Yoome 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 Women for Backpack Yoome Leather BookBag Black Campus Shoulder Vintage Bag Soft {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceLeather for Women Backpack BookBag Yoome Soft Shoulder Campus Black Vintage Bag .getWidth(),Coat Cardigan PLAER Elegant Fox Fur Faux Fashion Women Shawl Beige Cape xzzqwR4F0 source.getHeightShoulder Yoome Vintage Campus Soft BookBag Backpack Leather Women Bag Black for ());

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

  @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.

PicassoShoulder Leather Black Bag Backpack for Soft BookBag Campus Yoome Women Vintage .get().load(R.drawableGirls School Bags Travel Widewing Party Sequins Shining Teenage Backpacks Pink Mini Women fxaXZaq1.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.
