片段中的可点击卡片视图

Question

我有一个连接到片段的侧边导航抽屉。在一个片段中，我有三个 CardView 需要将我带到其他片段。我见过的所有示例都使用带有 ViewHolder 的 RecyclerView 来实现这一点，但我不想在这个上使用 RecyclerView。我已经为其中一个 CardViews 尝试了以下方法，但它似乎不起作用：

  public class Dashboard extends Fragment implements View.OnClickListener  {
    View view;
    CardView cardview1;


        @Nullable
        @Override
        public View onCreateView  (LayoutInflater inflater, @Nullable ViewGroup
                container, @Nullable Bundle savedInstanceState) {
            view = inflater.inflate(R.layout.dashboard_fragment, container, false);
            cardview1 = (CardView) view.findViewById(R.id.cardview_a);
            cardview1.setOnClickListener(this);
            return view;
        }

        @Override
        public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
            super.onViewCreated(view, savedInstanceState);
            getActivity().setTitle("Title");
        }


        @Override
        public void onClick(View v) {
        Fragment fragment;
            switch (v.getId()) {
                case R.id.cardview_a:
                fragment FragmentA();
                    break;
            }
        }
        }

    @Override
    public void onClick(View v) {
    Fragment fragment;
        switch (v.getId()) {
            case R.id.cardview_a:

            fragment = new FragmentA();     
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();  
            transaction.replace(R.id.container,fragment);
            transaction.commit();

          break;
        }
    }
