In this video Annyce shows you how to use the Realm RecyclerView adapter class in order to have auto-updating UIs.
- [Instructor] Now that we know how to query our data…we'll look at displaying it inside of a RecyclerView.…The most straightforward way is to get…the return result as a list…and just pass them to our adapter,…like we've done so many other times.…We're here inside of our RecipesActivity…and right underneath we get all of our recipes on line 52…let's hit Enter a few times…and we'll make a call to our Adapter.setRecipes method.…
And we're going to pass the list of allRecipes.…That's it, we can run the application now.…Once that's installed let's switch over to our emulator…and take a look.…We can see all of our recipes inside of our list.…So if we scroll we have our Cake,…the Pie, and the Pound Cake.…We don't need to do anything special outside…of standard Android components…in order to display Realm records in our UI.…
However, we can have more advanced integrations…if we take advantage of the Realm RecyclerViewAdapter.…We find out about this from the Realm documentation.…In the Working With Android section…we see that there's a special adapter Realm has created…
To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.
