Android Tutorial => Built-in two-way Data Binding

Example

Two-way Data-Binding supports the following attributes:

Element	Properties
`AbsListView`	`android:selectedItemPosition`
`CalendarView`	`android:date`
`CompoundButton`	`android:checked`
`DatePicker`	`android:year` `android:month` `android:day`
`EditText`	`android:text`
`NumberPicker`	`android:value`
`RadioGroup`	`android:checkedButton`
`RatingBar`	`android:rating`
`SeekBar`	`android:progress`
`TabHost`	`android:currentTab`
`TextView`	`android:text`
`TimePicker`	`android:hour` `android:minute`
`ToggleButton`	`android:checked`
`Switch`	`android:checked`

Usage

<layout ...>
    <data>
        <variable type="com.example.myapp.User" name="user"/>
    </data>
    <RelativeLayout ...>
        <EditText android:text="@={user.firstName}" .../>
    </RelativeLayout>
</layout>

Notice that the Binding expression @={} has an additional =, which is necessary for the two-way Binding. It is not possible to use methods in two-way Binding expressions.
