While you CAN fall back on Java for GUI components, you don't have to.
Most of my games have GUI widgets rendered in OpenGL, and every one of
the Lua-based frameworks mentioned have options for doing a basic GUI in
Lua without resorting to XML or Android-native controls. Any time to use
too much XML or too many native control features you lose a bit of
cross-platform portability.
The only time you HAVE to fall back to Java is when you're using a
third-party SDK (like Flurry) where it's supplied as a .JAR file. And
even then you CAN use JNI directly, or auto-binding code like luajava or
jnlua to call the Java APIs from your NDK-based app.

Well, Lua is an interpreter (though LuaJIT gets you JIT compilation on
Android). Most of the frameworks I'm familiar with either give you a
WebKit view and let you run JavaScript or they supply an interpreter
(Lua) or a VM (Mono). Not sure what Unity's doing, but it might compile
to Java.
