Lab $2$: Firebase RecyclerView

Ini$$al Set$-$up:

$1.$ Open your Lab $1$ Project you created last week

$2.$ Make sure you$$re logged into your google account in your browser

$3.$ Open Build.gradle $($Module$)$ and add the following to dependencies $($or the most recent version$)$:

Coding $$ MainAc$$vity$.$kt:

HINT: See KotlinReal$$meDB$.$zip in Week $3$ on eConestoga for help, the app is similar to this lab $4.$

$5.$ Inside onCreate add the following:

a val query: A query object searching the $$products$$ document

b val op$$ons: An op$$on object that connects the query with your Kotlin data class

c adapter: construct using ProductAdapter and passing op$$ons into the constructor

d val rView: A RecyclerView object which uses findViewById to connect to the

RecyclerView in ac$$vity$\_$main.XML file

e Set the adapter and layoutmanager proper$$es of rView $($it should use a

LinearLayoutManager$)$

$6.$ Add the onStart below onCreate with the following code:

Coding $$ ProductAdapter.kt:

$7.$ Set up your ProductAdapter class declara$$on like the PhoneAdapter class we covered in the Week $4$

lecture.

$8.$ Inside MyViewHolder: get references to the TextView widgets inside row$\_$layout.xml using findViewById

$9.$ Inside onBindViewHolder: display the name and price using the model$$s proper$$es

Zip your project and upload a screenshot of the device emulator displaying the data from Real$$me Database.

Do not zip the screenshot in the project folder, upload the screenshot separately.

The end result should be a RecyclerView displaying all the names and roles you put inside the products

database created in Firebase last week.

This is part $2$ of a $3$ part lab, so make sure you$$ve completed it correctly. Ask your professor if you have

any issues.
