Now that we've finished our adapter,
0:00
let's head over to our list
fragment's layout file.
0:02
And give our adapter
something it can work with.
0:04
Let's head over to the Text tab and
start by deleting the TextView.
0:07
Then, let's add in
a RecyclerView to hold our list.
0:13
And since we waned to take up the whole
screen, let set its width and
0:20
height to match parent.
0:24
We also wanna be able to
access this view from code.
0:27
So let's give it an ID,
Of listRecyclerView.
0:30
Then I'll add a backslash here and
that will end the tag.
0:40
Great job.
0:45
Now it's a jump to our list fragment
class and hook up a recycler view.
0:46
First we'll need to get
a reference to our recycler view.
0:52
Let's add some space
below the inflater and
0:55
create a new recycler
view named recyclerView.
0:59
And let's set it equal to
view.findViewById.ListRecyclerView.
1:04
And then use ALT enter to add the cast.
1:15
Next, let's create a new variable for
our ListAdapter as well.
1:20
But first I'm going to give myself
a little more room on the right.
1:24
Back to the List Adapter.
1:29
ListAdapter, let's name it ListAdapter and
set it equal to new ListAdapter.
1:35
Now that we have our ListAdapter let's
attach it to a recyclerView by calling
1:42
recyclerView.setAdapter and
passing it on our listAdapter.
1:46
Next we need to set a layout manager for
our recyclerView.
1:54
Remember the layout manager is responsible
for determining where to place the views,
1:58
as well as when to reuse a view
that's no longer visible.
2:03
To make our recyclerView
act like a vertical list,
2:08
we can use the built in
linear layout manager class.
2:11
Let's create a new variable for
our layout manager named LayoutManager.
2:15
And let's set it equal to
new LinearLayoutManager.
2:23
And for
the context let's pass in getActivity.
2:29
Fragments always have access to their
activity through the getActivity method.
2:33
We also could have used to get context.
2:38
Now that we've got our layout manager.
2:41
Let's attach it to our
recyclerView By calling recycler
2:44
view.setlayoutmanager and
passing it in our layout manager.
2:47
That should do it.
2:56
Let's test the app and see what happens.
2:57
Nice.
3:07
We've got a list of all our recipes
including pictures, and it scrolls up and
3:07
down too.
3:11
Perfect.
3:14
But this white background
is awfully bright.
3:15
Let's change this By opening
our styles.xml file and
3:18
the resources directory,
under the values directory and
3:23
changing the parent theme to just
the standard, theme.appcompat.
3:28
Now if we run the app again.
3:35
Welcome to the dark side.
