Goals
The goal here is to code an item-layout file to display information about a restaurant (name and rating).
This file will eventually be used by your adapter to display an item inside your RecyclerView
.
Required assets
The provided Resources folder for this part contains a subfolder named Completed with a solution you can use to check your work. There is also a folder named Assets which contains some pre-written code you will utilize. Please make sure you have these folders before you begin. This lab is a continuation of the previous one. If you did not complete the previous exercise, you can use the Completed solution from the previous part as starter code for this part.
Steps
Below are the step-by-step instructions to implement the exercise.
Sample data
- Add the provided file Assets/Restaurant.cs to your project.
- Open Restaurant.cs.
-
Take a moment to examine the code. Note that it contains a simple
Restaurant
class and a method to create some sample data.
Layout file
- Add a new Android layout file to your Resources/layout folder. Name it Restaurant.axml
-
Use a horizontal
LinearLayout
for the root of your layout file. (If your new file already includes a LinearLayout, make sure to set orientation to `horizontal` and the height to `wrap_content`.) -
Add the code shown below to the root layout. Notice how it matches
the sample restaurant data: a
TextView
for the name and aRatingBar
for the rating.<TextView android:id ="@+id/nameTextView" android:layout_alignParentBottom="true" android:textAppearance ="?android:attr/textAppearanceLarge" android:layout_marginLeft ="16dp" android:layout_marginRight ="16dp" android:layout_width ="200dp" android:layout_height ="wrap_content" /> <RatingBar android:id ="@+id/ratingBar" android:layout_alignParentRight="true" android:layout_width ="wrap_content" android:layout_height ="wrap_content" style ="?android:attr/ratingBarStyleSmall" android:numStars ="5" />
- Compile your app. You do not need to run it since it will not display any output.
Summary
In this exercise, you created a layout file to display information about a Restaurant object. This file defines the item UI
that RecyclerView
will display for you.
