I am trying to get a very basic application that will play with Material Design. I am trying to create a Listview (using the new RecyclerView) as each item is a map that has Google Maps Lite in it.
I basically stuck with this example: Creating lists and cards , for implementing Google Maps I used this example
Every thing “Works” when I have only one element in the adapter (so there is only one element to display) but when I add the second element to the adapter (so there should be two elements in the list), the application crashes:

Can someone tell me what I am doing wrong?
Besides the error, I can’t understand what would be the best way to set properties on separate cards (in the center, etc.). Help in this area will also be appreciated.
Implementation for reference:
Activities
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main, container, false); mRecyclerView = (RecyclerView) rootView.findViewById(R.id.main_recycler_view); mLayoutManager = new LinearLayoutManager(context); mRecyclerView.setLayoutManager(mLayoutManager); ArrayList<String> data = new ArrayList<>(); data.add("Toeter"); mAdapter = new MyAdapter(data, getChildFragmentManager()); mRecyclerView.setAdapter(mAdapter); return rootView; }
Myadapter
@Override public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { final View v = LayoutInflater.from(parent.getContext()) .inflate(R.layout.card, parent, false); ViewHolder vh = new ViewHolder(v); return vh; }
ViewHolder
public static class ViewHolder extends RecyclerView.ViewHolder { public ViewHolder(View v) { super(v); } }
