@f.babic: Under the hood, it just uses a SparseArray to cache the views. When you reference my_view, it compiles to a call to a synthetic function, _$_findCachedViewById, which checks the sparsearray if the ID is already in the mapping... if so, it returns the view. Otherwise, it calls findViewById, adds the view to the cache, and returns the view. You can clear the cache with clearFindViewByIdCache()
