fun ImageView.load(imageUrl: String, picasso: Picasa) {...}

and inject Picasa in your activity

[Jorge R]

You can also create your own component that will contain Picasa already

[Jorge R]

but that requires a bit more work

[Jorge R]

I see it a bit ugly to continuously send picasa, but there is no other way with a function extension

[Paul Woitaschek]

Use Picasso as a default parameter

[Paul Woitaschek]

fun ImageView.load(imageUrl: String, @VisibleForTesting picasso: Picasso = Picasso.get())

[Jorge R]

true

[Jorge R]

mmm previously i was using Picasso.with(context).load(URL).into(imageView)

[Jorge R]

is the context not needed anymore?

[Paul Woitaschek]

Correct

[Jorge R]

ah ok, then that could be the reason why i didnt consider a default parameter

[Jorge R]

but now it works like a charm

[Paul Woitaschek]

Btw if you go fancy you could pass a function 😉

[Paul Woitaschek]

fun ImageView.load(imageUrl: String, picasso: (Context) -> Picasso = { Picasso.with(it) }) {
  if (imageUrl.isNotEmpty()) {
    picasso(context).load(imageUrl).into(this)
  }
}

[Jorge R]

nice

[Jorge R]

I will give this a try

[Abdul Kadir]

@Paul Woitaschek is that a default value for the function? I'm not familiar with that syntax. Sorry if it's stupid, I'm still learning :p

[Paul Woitaschek]

Yes it is

[Paul Woitaschek]

picasso: (Context) -> Picasso

[Paul Woitaschek]

the parameter picasso is a function that takes a Context and returns an instance of Picasso.

[Paul Woitaschek]

= { Picasso.with(it) }

[Paul Woitaschek]

By default this function is a lambda and returns Picasso.with(it) when called (where it is a context)
