Downloading Images With Picasso Android Disck

I'm using the Picasso library to download and display images in a listview, I'm using the following code: Picasso.with(mContext).load(listItem.getMainPhoto()).into(holder.image)

Solution 1:

i know this is a old question but maybe someone can find this useful.

you can download an image with picasso using a target:

Picasso.with(mContext)
    .load(listItem.getMainPhoto())
    .into(target);

privateTarget target = newTarget() {
    @OverridepublicvoidonBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
        newThread(newRunnable() {
            @Overridepublicvoidrun() {               

                File file = newFile(Environment.getExternalStorageDirectory().getPath() +"/imagename.jpg");
                try
                {
                    file.createNewFile();
                    FileOutputStream ostream = newFileOutputStream(file);
                    bitmap.compress(CompressFormat.JPEG, 75, ostream);
                    ostream.close();
                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }

            }
        }).start();
    }
    @OverridepublicvoidonBitmapFailed(Drawable errorDrawable) {
    }

    @OverridepublicvoidonPrepareLoad(Drawable placeHolderDrawable) {
        if (placeHolderDrawable != null) {
        }
    }
};

To clean the cache you can add this class to the picasso package:

package com.squareup.picasso;

publicclassPicassoTools {

    publicstaticvoidclearCache(Picasso p) {
        p.cache.clear();
    }
}
