Connecting a dataset
Android comes equipped with the SQLite library, which is a powerful tool for creating and managing complex databases. One could easily fill an entire chapter, or even a whole book, on the subject, but as this does not really bear any relation to Material Design, we will create a very simple dataset just so that we can test out our RecyclerView.
If you would like to learn more about SQLite, comprehensive documentation can be found at http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html.
For the sake of brevity, the example here contains only three entries; however, it is very easy to expand if you choose. To add this data, create a new Java class called Contact.Java and complete like so:
public class Contact {
intprofilePic;
String name;
String status;
private List<Contact> contacts;
Contact(intprofilePic, String name, String status) {
this.profilePic = profilePic;
this.name = name;
this.status = status;
}
private void loadData...
