Also, make sure you are using a compatible version of Android Studio. -Android Studio 1.3 adds the code-completion and layout-preview -support for data binding.
+Android Studio 1.3 and later provides support for data binding as described in +Android Studio Support for Data Binding. ++Android Studio supports syntax highlighting of data binding expressions, and flags any expression +language syntax errors in the editor. +
+
+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 TextView.
+
+<TextView android:layout_width="wrap_content"
+ android:layout_height="wrap_content"
+ android:text="@{user.firstName, default=PLACEHOLDER}"/>
+
+
++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. +
