Of course you can. Its actually pretty straight forward:
File f = new File("path-to-file/file.png");
or
File f = new File(uri);
Picasso.get().load(f).into(imageView);
also
Picasso.get().load(uri).into(imageView);
works
Pregunta
Can I use Picasso library to load images from the filesystem?
I'm using startActivityForResult
to let the user pick a photo from his gallery, and then want to show the selected image.
I already have working code to get the image filesystem Uri
, but can't get the Picasso.load()
method to work.

Yes you can.
Try:
Picasso.with(context).load(new File(YOUR_FILE_PATH)).into(imageView);
EDIT
You can also call .load(YOUR_URI)
instead as well.
Looking in the source code I also discover that you can load the image from filesystem adding file:
string prefix to your image path. For example:
file:path/to/your/image
Also, when using startActivityForResult, you will get something like this:
Uri imageContent = data.getData();
Then, you can call Picasso.with(getContext()).load(imageContent.toString).into(imageView);
directly without need to create a Cursor
and querying for the image path.
Try this:
Picasso.with(context)
.load("file://"+path) // Add this
.config(Bitmap.Config.RGB_565)
.fit().centerCrop()
.into(imageView);
It work perfect for me.
> Picasso.get().load(R.drawable.landing_screen).into(imageView1);
> Picasso.get().load("file:///android_asset/DvpvklR.png").into(imageView2);
> Picasso.get().load(new File(...)).into(imageView3);
Basically we need three things, Context
, image´s path
and the ImageView
Container
Old version of Picasso:
Picasso.with(context).load("/files/my_image.jpg").into(myImageView);
Newer version of Picasso:
Picasso.get().load("/files/my_image.jpg").into(myImageView);
but we can make use of more options:
.resize(20, 20)
.centerCrop()
.placeholder(R.drawable.user_placeholder)
.error(R.drawable.user_placeholder_error)
etc...

If anyone trying to do this with Kotlin then here it is...
//variables
private lateinit var addImage: ImageView // set the id of your ImageView
private lateinit var imageUri: Uri
//open gallery to select an image
val gallery = Intent()
gallery.type = "image/*"
gallery.action = Intent.ACTION_GET_CONTENT
startActivityForResult(Intent.createChooser(gallery, "Select picture"), PICK_IMAGE)
//next
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PICK_IMAGE && resultCode == RESULT_OK) {
imageUri = data?.data!!
try {
Picasso.get()
.load(imageUri)
.into(addImage)
} catch (e: Throwable) {
e.printStackTrace()
}
}
}
That's all you need.
