Quero entrar em uma nova atividade com o método onClick (), mas meu código não está funcionando. Você pode, por favor, oferecer alguns conselhos. Estou com alguns problemas com o recyclerView, pois é relativamente novo para mim. Obrigado

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;
            }
        }

    }
