logcat错误:没有连接适配器; 跳过布局

我用getActivity()更改了context参数,但应用程序仍未运行.

public class FragmentActivity extends Fragment {  
    private RecyclerView mRecyclerView;
    private CountryAdapter mAdapter;
    private LinearLayoutManager layoutManager;
    public FragmentActivity(){}
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.activity_main, container, false);
        mRecyclerView = (RecyclerView) rootView.findViewById(R.id.list);
        layoutManager = new LinearLayoutManager(getActivity());
        mRecyclerView.setLayoutManager(layoutManager);
        mRecyclerView.setAdapter(mAdapter);
        mAdapter = new CountryAdapter(CountryManager.getInstance().getCountries(), R.layout.card_layout, getActivity());
        return rootView;
    }
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }
}

我是c#的新手,而且我在实施接口方面有点挣扎,如果有人帮我解决这个问题,我将非常感激.谢谢

namespace interfejsi
 interface Figura
{
  String Plostina ();
  String Perimeter ();
}
}

 class Kvadar : Figura
{
    int a,b,c;
    public  String Perimetar(int a, int b, int c)
    {
        return (a + b + c).ToString();
    }
    public String Plostina(int a, int b, int c)
    {
        return (a * b * c).ToString();
    }
}
