Here you load res/layout/mainmenu.xml.

Here you try to find recommendationList in res/layout/mainmenu.xml.

Here you say the layout you're aiming for is res/layout/Recommendation.xml.

Here is a recommendationList in res/layout/Recommendation.xml.
If all those are correct, then you may be loading the wrong layout,
which would make your recommendationList variable null after the
findViewById() call.
Also, I recommend all resources (layouts, etc.) be named in all
lowercase, since on some platforms you can have a Recommendation.xml and
a recommendation.xml, but Android ignores case in the R.java generation,
which may cause confusion.
