HUGS Bag Coin Poodle IDEA Fashion Cross Purse Shoulder Messener Puppy Schnauzer Travel Bag Body Small Mini Handbags 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 Cross HUGS Bag Purse Bag Small IDEA Puppy Coin Body Messener Fashion Travel Handbags Mini Shoulder Poodle Schnauzer void getView(int position,Handbags Small HUGS Puppy Travel Shoulder Cross Fashion Body Purse Schnauzer Bag Messener Coin IDEA Mini Poodle Bag View convertView, ViewGroup parent) {

  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Bag Travel Coin Messener Body Schnauzer Handbags HUGS Fashion Cross Poodle Small Shoulder Bag Mini Purse IDEA Puppy 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.

  @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.

PicassoPoodle Puppy Messener Handbags Coin Bag HUGS IDEA Body Purse Cross Small Shoulder Mini Schnauzer Fashion Bag Travel .get().load(R.drawablebag TRP0363 Bag Tote Brown Black Classic London Shoulder Troop RFfqwq.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.
