Data Binding
Data binding allows you to connect your model (data) to your view with just a few lines of code. To demonstrate data binding, we’ll modify the Events example to use a ListView that’s bound to the result of a database query. First, we need to make the MainActivity class extend ListActivity instead of Activity:
| eventsv2/src/main/java/org/example/events/MainActivity.java | |
| | import android.app.ListActivity; |
| | // ... |
| | public class MainActivity extends ListActivity { |
| | // ... |
| | } |
Next, we need to change how the events are displayed in the MainActivity.showEvents method:
| eventsv2/src/main/java/org/example/events/MainActivity.java | |
| | import android.widget.SimpleCursorAdapter; |
| | // ... |
| | private static int[] TO = { R.id.rowid, ... |
