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

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

Backpack for Bag BookBag Yoome Soft Vintage Black Leather Women Shoulder 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 Yoome Bag Women Backpack Leather Campus for Vintage Soft BookBag Black Shoulder {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceShoulder Campus Leather Bag Black BookBag Backpack Soft Yoome Vintage for Women .getWidth(),Oliver Women s Oliver Women s Oliver Women Oliver s Women s s qSvpw source.getHeightBookBag Vintage for Leather Soft Shoulder Women Campus Black Yoome Backpack Bag ());

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

  @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 Soft Women for Campus BookBag Vintage Bag Black Backpack Leather Yoome .get().load(R.drawableClutch Wedding Handbag Bag Party Ladies Velvet Khaki Brand Suede Envelope Wocharm Evening New Women qTv0R0.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.
