Checking It Twice3:42 with Ben Deitch
In this video we finally get to see our list!
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. 3:40
