Make conditional work properly when toggle it in QS

Some conditionals do not work properly when users toggle its state in
QS, the cause is that these conditionals don't have a way to monitor the
status changed. Make RecyclerView handle onWindowFocusChanged event and
make sure that conditionals can update the status when going back to
Settings from QS.
