Picasso load drawable resources from their URI

Found the answer. Unfortunately, Picasso do not allow drawable loading via URI. It is an incoming feature.

If the images is in your drawable folder then you can just load it.

Picasso.with(context).load(R.drawable.drawableName).into(imageView);

and picasso will load it no need for an Uri.

From picasso v2+ here is a big modification. The new version is very helpful in order to manage image cache data. It's using Singleton Instance.

GRADLE

implementation 'com.squareup.picasso:picasso:2.71828'

Set drawable image

Picasso.get()
    .load(url)
    .placeholder(R.drawable.user_placeholder)
    .error(R.drawable.user_placeholder_error)
    .into(imageView);

Bonus, get drawable by name:

public static int getDrawableIdFromFileName(Context context, String nameOfDrawable) {
        return context.getResources().getIdentifier(nameOfDrawable, "drawable", context.getPackageName());
}

• This is if you don't want to hardcode the image that you are going to load...

You can load local image files from your drawable folder lazily if you know the integer value of the image that you want to be loaded.

Then you can just do:

Picasso.with(getContext()).load(imageResourceId)
.error(R.drawable.ic_launcher)
.into(imageView);

Where

imageView

is the view you wish to display the image. For example:

imageView = (ImageView) convertView
.findViewById(R.id.itemImage);

And where

imageResourceId

is the integer value of the drawable. You can retrieve this integer value by:

int productImageId = resources.getIdentifier(
productImageName, "drawable", context.getPackageName());

as well as

productImageName

is the name of the drawable you want to draw (i.e. "ic_launcher")

THIS CAN ALL BE DONE INSIDE FROM THE ADAPTER
