[patjackson52]

Now that Google has announced RecyclerView in the supportLib it would be great to have use FAB with this new view.

This would be important to have before the L release, too

I`m needing this one too... I have dig a little deeper and recyclerview inherits direct from ViewGroup. Any idea on this? maybe it is easy to add support. It throws some error on focusable methods....

java.lang.NullPointerException at android.support.v7.widget.RecyclerView.addFocusables(RecyclerView.java:1486) at android.view.ViewGroup.addFocusables(ViewGroup.java:797) at android.view.ViewGroup.addFocusables(ViewGroup.java:797) at android.view.ViewGroup.addFocusables(ViewGroup.java:778) at android.view.View.getFocusables(View.java:5185) at android.view.FocusFinder.findNextFocus(FocusFinder.java:114) at android.view.FocusFinder.findNextFocus(FocusFinder.java:98) at android.widget.ScrollView.onRequestFocusInDescendants(ScrollView.java:1357) at android.view.ViewGroup.requestFocus(ViewGroup.java:2113) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2110) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2110) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2110) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2110) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2110) at android.view.ViewGroup.onRequestFocusInDescendants(ViewGroup.java:2154) at android.view.ViewGroup.requestFocus(ViewGroup.java:2113) at android.view.View.requestFocus(View.java:5323)

You need to set a layout manager to your recycler view before setting an adapter or anything else

Hello,

I tried adding recyclerview in Content area. Now parallex is not working. Can you suggestion someething please.

FadingActionBarHelper helper = new FadingActionBarHelper() .actionBarBackground(R.drawable.ab_background_light) .headerLayout(R.layout.header) .contentLayout(R.layout.content); setContentView(helper.createView(this)); helper.initActionBar(this);

    mRecyclerView = (RecyclerView)findViewById(R.id.recycler_view);
    //mRecyclerView.setHasFixedSize(true);
    mLayoutManager = new LinearLayoutManager(this);
    mRecyclerView.setLayoutManager(mLayoutManager);
    mAdapter = new CardAdapter();
    mRecyclerView.setAdapter(mAdapter);

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>
