title: Overscroll effect from bottom not appearing when using RecyclerView inside SwipeRefreshLayout
body: <p>I am trying to make a list with the nice pull to refresh feature but when I have a RecyclerView inside an SwipeRefreshLayout the overscroll effect only works when it is refreshing. Even for the bottom of the list. What happens is that the user don't have that visual cue that the list has ended.</p>
  
  <p>Here's my XML:</p>
  
  <pre><code>&lt;android.support.v4.widget.SwipeRefreshLayout
      android:id="@+id/swipe_refresh"
      android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
  
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/recycler_vew"
          android:layout_width="match_parent"
          android:layout_height="match_parent"/&gt;
  
  &lt;/android.support.v4.widget.SwipeRefreshLayout&gt;
  </code></pre>
  
  <p>And the Class from the Fragment:</p>
  
  <pre><code>public class MyListFragment extends Fragment implements SwipeRefreshLayout.OnRefreshListener {
      private SwipeRefreshLayout swipeRefreshLayout;
      private RecyclerView recyclerView;
  
  
      static final String[] lines = new String[]{
          "this is line #1",
          "this is line #2"
          "this is line #3"
          "this is line #4"
          "this is line #5"
          "this is line #6"
          "this is line #7"
      };
  
      @Override
      public void onRefresh() {
          Log.i("QUESTION_LIST_REFRESH", "onRefresh called from SwipeRefreshLayout");
          new Handler().postDelayed(new Runnable() {
              @Override public void run() {
                  swipeRefreshLayout.setRefreshing(false);
              }
          }, 4000);
      }
  
      @Override
      public void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setHasOptionsMenu(true);
      }
  
      @Override
      public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
          super.onViewCreated(view, savedInstanceState);
  
          recyclerView = (RecyclerView) view.findViewById(R.id.questions_list);
  
          swipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_refresh_question_list);
          swipeRefreshLayout.setOnRefreshListener(this);
          swipeRefreshLayout.setColorSchemeColors(
                  ContextCompat.getColor(getContext(),R.color.colorPrimaryDark),
                  ContextCompat.getColor(getContext(),R.color.colorAccent));
  
      }
  
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
                               Bundle savedInstanceState) {
          View view = inflater.inflate(R.layout.fragment_list, container, false);
  
          recyclerView = (RecyclerView) view.findViewById(R.id.recycler_vew);
          recyclerView.setHasFixedSize(true);
  
          RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getContext());
          recyclerView.setLayoutManager(layoutManager);
  
  
          recyclerView.setAdapter(new MyListAdapter(lines));
  
          return view;
      }
  }
  </code></pre>
