Example App: RecyclerView with Kotlin on Android

Finished source code for the blog article introducing RecyclerView with Kotlin support on Android. Follow the instructions to go from a new project in Android Studio to a fully-working RecyclerView list.

• Part 1: Kotlin & RecyclerView for High Performance Lists in Android
• Part 2: How To: RecyclerView with a Kotlin-Style Click Listener in Android
• Part 3: How-To: Retrofit, Moshi, Coroutines & Recycler View for REST Web Service Operations with Kotlin for Android

Example projects

• 01 Offline variant: The finished solution for Part 1 + 2 is in the 01-RecyclerView directory. This contains a fully working Recycler View project with a click listener written in Kotlin. It uses test data added during onCreate().
• 02 + 03 Web Service variant: Part 3 of the article series added dynamically retrieving and updating data through a REST web service. Find the starter project in 02-Retrofit-Start; the article walks you through the implementation steps. The final solution of the recycler view project with added web access is in 03-Retrofit-Solution.

Mock Server for examples 02/03: find details how to install and run the local mock server for parts 2 + 3. Short summary:

1. Install Node.js
2. Install the json-server module globally: npm install -g json-server
3. Run the server from the root directory of this repository, which contains the sample database (db.json): json-server --watch db.json. Note: to access the web server from your phone instead of the emulator, run it with your computer's local IP address, e.g.: json-server --watch db.json --host <yourIp>

Updates

December 15th, 2020: Updated project to use Jetpack View Binding instead of the Kotlin synthetics.

partslist's Issues

Data load slow

Hy
I would like to use your solution for simple onclick with 90.000 row database. When I search in my db and trying to show result list in recyclerview it is very slow with this solution . With normal recycleradapter is fast so it isn't the db or query problem.
