We're super close to having the bottom of our layout done.

There's just one more thing we need to add.

If we go back to the developer page in Dark Sky and look here in the overview.

Scroll down here to terms of service.

I'm not going to read this all, or go through it section by section.

But before you use it in your app,

you should familiarize yourself with any terms of service an API has.

The main one we need to concern ourselves with for

Stormy is this attribution section.

In a nutshell, it states that we need to display a Powered by Dark Sky message and,

if possible, make the text open a given webpage.

Let's head back over to Android Studio, add in the text view with the required

message and make the text a link to their site.

So let's grab a new text view.

We can strain it to the bottom.

To the left, or to the right.

Let's make this a little bit bigger.

We'll call this darkSkyAttribution.

For our default text we want it to be Powered by Dark Sky.

And for the text color, we want it to be our 50% white.

Okay, now we need to make this a link to open up the Dark Sky website.

It's fairly simple to do but there are some steps involved, so stick with me.

First, we need to add the URL to our text and

the best way to do that is by making this text a string resource.

So, let's go back up here.

We'll add a new resource.

We'll call it dark_sky_message, and we'll put Powered by Dark SKy in there.

Now we need to head over to the strings.xml file and

add the URL information to our resource.

So values, strings.

We see our string resource that we just named dark_sky_message in here.

We need to wrap our message text in an HTML anchor tag and

give the href value of the URL.

If you aren't familiar with HTML anchor tags and

href values, I've put some information in the teacher's notes about them.

To start with, we need to wrap our anchor tag around the text.

We'll add an anchor tag there, and our closing anchor tag.

Now we need to add the href and

url information from Dark Sky to the opening of our anchor tag.

Come in here.

Href, and their URL is

https://darksky.net/poweredby.

Great!

That wasn't too painful.

And if we go back and run our app, we should see our text as a link now.

And if we click on it, nothing happens.

Also looks like our degree symbol got out of alignment here, so we'll fix that too.

Let's tackle that degree symbol first.

There it is, there isn't a constraint.

So we'll put the left to the right of the temperature value.

Okay, so what's going on with our link?

Well, we still need to tell Android to do something when we click on it.

There are a few different ways we could go about this.

We could write an onClick listener for instance.

But let me show you a way that only takes a couple of lines of code

in main activity.

Let's head over there to set that up.

So we go over to MainActivity.

So here in our onCreate method, right after we call the setContentView,

let's define a new TextView named darkSky.

We want to find the view by the ID that we set a little bit ago, so findViewById.

I think it was darkSkyAttribution, there it is.

Now we need to tell Android to enable the links inside this text view object.

We can do that with the set movement method.

So darkSkySetMovementMethod();.

This method takes a parameter, a movement method.

There is a movement method named link movement method that supports

clicking on links, and we'll want to get that instance should we click on the link.

So LinkMovementMethod.getInstance, and that's it.

Now we can run our app.

And when we click on the link, We're taken to the Dark Sky site.

Pretty slick, eh?

Our layout is just about wrapped up.

And it's great that we have added that attribution to Dark Sky.

That'll make the attorneys happy.

We're nearing completion of our Stormy app and you're doing great.

The next step is to connect or

bind the data we are getting from the Dark Sky API to our new interface.

Let's see how to do that in the next stage.
