android:load image from sdcard with picasso

问题

is it possible to use picasso library to load image from sdcard to imageView ?

回答1:

As picasso doc provided,

Resources, assets, files, content providers are all supported as image sources.

You can simply do like it

String filename = "YOURIMAGE.png";
String path = "/mnt/sdcard/" + filename;
Picasso.with(context).load(new File(path)).into(imageView);

Edit

As @Budius suggested, the better way to access file from disk path, use Enviroment class.

String filename = "YOURIMAGE.png";
String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
Picasso.with(context).load(new File(baseDir + File.separator + filename)).into(imageView);

Hope it will work for you.

You need to first convert your image to a Uri, and then load it using Picasso the same way you did for any images.
