 must configure data binding in its <code>build.gradle</code> file as well.</p>

<p>

Android Studio supports syntax highlighting of data binding expressions, and flags any expression

language syntax errors in the editor.

</p>

<p>

The Preview pane displays default values for data binding expressions if provided. In the following

example excerpt of an element from a layout XML file, the Preview pane displays the

{@code PLACEHOLDER} default text value in the <code>TextView</code>.

</p>

<pre>

<TextView android:layout_width="wrap_content"

   android:layout_height="wrap_content"

   android:text="@{user.firstName, default=PLACEHOLDER}"/>

</pre>

<p>

If you need to display a default value during the design phase of your project, you

can also use tools attributes instead of default expression values, as described in

Designtime Layout Attributes</a>.
