Quiero entrar en una nueva actividad con el método onClick () pero mi código no funciona. ¿Puedes por favor ofrecer algún consejo? Tengo algunos problemas con el recyclerView, ya que es bastante nuevo para mí. Gracias

public class FragmentOne extends Fragment {

        @Nullable
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            RecyclerView recyclerView = (RecyclerView) inflater.inflate(
                    R.layout.recycleview, container, false);
            ContentAdapter adapter = new ContentAdapter();
            recyclerView.setAdapter(adapter);

            recyclerView.setHasFixedSize(true);
            recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
            return recyclerView;
        }

        public class ContentAdapter extends RecyclerView.Adapter<Content,Adapter.ViewHolder> {
            private static final int LENGTH = 50;

            public ContentAdapter() {
            }

            public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

                public ViewHolder(LayoutInflater inflater, ViewGroup parent) {
                    super(inflater.inflate(R.layout.fragment_channel, parent, false));
                }

                @Override
                public void onClick(View v) {
                    Intent intent = new Intent(getActivity(), ChannelDetailActivity.class);
                    startActivity(intent);
                }
            }

            @Override
            public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

                ViewHolder viewHolder = new ViewHolder (LayoutInflater.from(parent.getContext()), parent);
                return viewHolder;

            }

            @Override
            public void onBindViewHolder(ViewHolder holder, int position) {
            }

            @Override
            public int getItemCount() {
                return LENGTH;
            }
        }

    }
