Ich möchte mit der onClick () -Methode in eine neue Aktivität einsteigen, aber mein Code funktioniert nicht. Können Sie uns bitte einen Rat geben? Ich habe einige Probleme mit dem recyclerView, da er für mich ziemlich neu ist. Vielen Dan

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;
            }
        }

    }
