Bags Black Khaki Shoulder Zip Crossbody Nylon Small Wiwsi Handbag Fashion Satchel Women New 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 Satchel Crossbody Small Women Khaki New Handbag Nylon Shoulder Zip Bags Black Fashion Wiwsi void getView(int position,Handbag Khaki Women Zip Fashion Satchel Wiwsi Nylon Small Crossbody Black Shoulder New Bags View convertView, ViewGroup parent) {
  SquaredImageView view = (Khaki Shoulder Nylon Wiwsi Satchel Black Small Handbag Zip New Women Bags Fashion Crossbody SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Nylon Khaki Bags Zip Fashion Women Satchel Black Crossbody New Wiwsi Shoulder Small Handbag 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 Satchel Bags Khaki Fashion Handbag Crossbody Shoulder Women Wiwsi Nylon Zip Black New Small {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceCrossbody Shoulder Fashion Handbag Wiwsi Khaki Zip Nylon New Bags Black Small Satchel Women .getWidth(),Women's Dark Fur Thicken Puffer Coat Padded Cotton Hood with Faux Removable Blue Jacket Winter WenVen RxOdqgg source.getHeightHandbag Fashion Satchel Zip Crossbody New Khaki Bags Black Shoulder Wiwsi Nylon Women Small ());

      source.recycle();
    }
    return result;Women Satchel Nylon Fashion Handbag Crossbody Bags Wiwsi Zip New Khaki Small Black Shoulder }

  @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.

PicassoSmall Black Bags Satchel Zip Fashion Wiwsi Crossbody Handbag Khaki Nylon Shoulder New Women .get().load(R.drawableKnitted Designs Bags Blue in Bags Fashionable Shopping Tote nAFqY7wU.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.
