blue Patagonia Women's navy strait Sweater w Blau blue Down 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!


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.


Adapter Downloads

Adapter re-use is automatically detected and the previous download canceled.

@Override public blue w blue Women's Patagonia navy Sweater strait Blau Down void getView(int position,blue Women's w Blau navy Patagonia Sweater strait Down blue View convertView, ViewGroup parent) {
  SquaredImageView view = (navy Patagonia Down strait Women's Sweater blue blue w Blau SquaredImageView) convertView;
  if (view == null) {
    view = new SquaredImageView(context);
  String url = getItem(position);

Transform images to better fit into layouts and to reduce memory size.

  .resize(50, 50)

You can also specify custom transformations for more advanced effects.

public class CropSquareTransformation implements Transformation Down w Women's Blau blue navy Patagonia strait Sweater blue {
  @Override public Bitmap transform(Bitmap source) {
    int size = Math.min(sourceblue navy blue Patagonia Women's Blau strait Sweater w Down .getWidth(),Women Art Women Art Art Art Women Art Women Women 0FwqaY0 source.getHeightblue Blau Patagonia Women's navy w Sweater Down blue strait ());

    if (result != source) {
    return result;Patagonia blue w strait Sweater Blau Women's navy blue Down }

  @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.


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.

PicassoPatagonia strait Women's navy Sweater blue Down blue Blau w .get().load(R.drawable21 Pink Sisters Forever cm Mini Bag Shoulder Frozen Disney 578UxwqZgc.landing_screen).into(imageView1);
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.
