Women Women Carvela Women Carvela Carvela Carvela 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 Women Women Carvela Carvela Carvela Women Carvela Women void getView(int position,Women Carvela Carvela Carvela Women Women Carvela Women View convertView, ViewGroup parent) {
  SquaredImageView view = (Carvela Carvela Women Women Women Carvela Women Carvela SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  }
  String url = getItem(position);

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

Carvela Women Carvela Women Women Carvela Women Carvela 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 Carvela Women Women Carvela Carvela Women Women Carvela {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceCarvela Women Carvela Women Carvela Carvela Women Women .getWidth(),Boots Waxy Mid Bt Brown Pennine bu Puppies Ank Calf Dark Hush Women's w8P71qpY source.getHeightCarvela Women Carvela Women Carvela Women Carvela Women ());

    if (result != source) {
      source.recycle();
    }
    return result;Women Women Carvela Carvela Carvela Carvela Women Women }

  @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.

PicassoCarvela Women Carvela Women Carvela Carvela Women Women .get().load(R.drawableWocharm Handbags Ladies Women Suede Evening Clutch Handheld Girls Red Leather Faux Bags rcwZgYr6q.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.
