Added instructions for RecyclerAdapter cleanup & corrected method names

Somebody that wants to jump right in and use the `RecyclerAdapter`, might just skip through the `ListAdapter` example and forget to call `cleanup()` on it.

Also, the method name seemed to be incorrect in the instructions but right in the code: instead of `release()` the correct method is `cleanup()` just like above.

Make sure that the click listener gets attached to the login buttons

Changed setListAdapter to setAdapter

setListAdapter only exists for ListActivities, but this example seems to be using ListViews

Rename layout to view

Buttons are not layouts, so let's use the name of the top-level class
they share View.
