Make Ctrl+F11 launch Android project even when on XML file

Ctrl+F11 on Eclipse is a life saver. Unfortunately, it only works when the currently selected file tab is of a .java file. It doesn't work when the currently selected file tab is of an .xml file.

I searched this great SO resource and found something very similar to what I am looking for but unfortunately the solution offered simply doesn't work for XML in an Android project.
