        rl_share=(RelativeLayout)view.findViewById(R.id.rl_share);
        rl_share.setOnClickListener(new View.OnClickListener()

                Intent intent = new Intent(context, Share.class);
                context.startActivity(intent);
            }

Try this

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<ContentAdapter.ViewHolder> implements View.OnClickListener {
        private static final int LENGTH = 50;

        public ContentAdapter() {
        }

        public class ViewHolder extends RecyclerView.ViewHolder {

            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;
        }
    }
}

The adapter now implements the onclick and not the viewholder.

Answer 3

Just change getContext() to v.getContext() like this:

        @Override
        public void onClick(View v) {
           v.getContext().startActivity(new Intent(v.getContext(), ChannelDetailActivity.class));

        }

And make your ViewHolder class an inner class of your ContentAdapter class.

Answer 4

you have to create constructor of FragmentOne like this

Activity activity;
FragmentOne(Acticity activity){ 
     this.activity = activity;
}

After that start activity with the reference of that activity like this

activity.startActivity(intent);
