私は、マテリアル デザインをいじる非常に基本的なアプリを取得しようとしています。私はリストビューを作成しようとしています (新しい RecyclerView を使用)。すべてのアイテムはカードの魔女であり、Google マップ ライトが含まれています。
私は基本的にこの例に従っています:リストとカードの作成 、Google マップの実装では、この例を使用しています
アダプターに項目が 1 つしかない場合 (つまり、表示する項目が 1 つしかない場合) はすべて「動作」しますが、アダプターに 2 つ目の項目を追加すると (リストに項目が 2 つあるはずです)、アプリがクラッシュします。例外：

誰が私が間違っているのか教えてもらえますか?
エラーに加えて、個々のマップ（中心など）にプロパティを設定する最良の方法が何であるかを理解できないようです。その分野での助けも本当にありがたいです。
参照用の実装:
アクティビティ
@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;
}
マイアダプター
@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;
}
ビューホルダー
public static class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View v) {
super(v);
}
}
