Use string format arguments in Android layout xml file

I have a string defined in my String.xml file that uses format arguments, i.e.:

<string name="myString">Hello %1$s.</string>

Is there a way to assign a value to the format argument in a layout xml file? I have something like:

<TextView android:text="@string/myString"/>

I know I can do it in java, but is there a way to do it here?

Thanks!
