The ContentValues class is used as a proxy for your application's data. Explore its usage in this video.
- [Instructor] In order to insert data into your…SQLite database, you will need to use the…ContentValues class.…Let's add a new method to our data source class…that will handle inserting records in our database.…Let's add it underneath the close method,…and we're going to call this createRecipe.…So I'm going to type public…void…createRecipe.…It's going to accept a recipe object as its input,…so we can type Recipe here,…and let's name the variable recipe.…
I'm going to type Alt Enter to make sure I…accept that import.…Great.…Now we're going to add our curly braces,…and then we can start to work on this method.…What we ultimately want is to execute the database's…insert method in order to store this recipe.…So we'll start by typing database.insert.…If we take a look at the required parameters…for this method, we can see that we need to pass…the table name, the null column hack value,…and finally, a content values object.…
Let's add these one at a time.…So first we need to pass the table name.…Since we want this inserted in the recipe table,…
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.
